Eyes – ‘Shortening of the Eye’ or Squinting – Dog Body Language

‘Shortening of the eye’ is a dog body language term used to describe when a dog squints his eyes slightly to deliberately soften them when interacting with another individual. It is used as a non-confrontational signal to indicate peaceful intentions in situations were there may be direct eye contact. In dog body language, direct eye contact or staring could be seen as confrontational; a hard stare in combination with a freeze of body is used as a warning. When a dog is relaxed, the eyes appear almond shaped and soft. To clearly indicate peaceful intentions, the dog may accentuate the eyes even further by squinting.

Depending on the context, body language signals, and what the rest of the dog’s body position is conveying at the time, squinting may also be used when a dog is displaying appeasement. In the case of appeasement, the eye may be squinted almost totally shut, which is different to the subtle slight squint involved in ‘shortening of the eye’. A dog that is showing appeasement signals may also be feeling some fear and may either freeze or crouch. It is best not to approach a fearful dog. There is a big difference in body language between a dog showing appeasement and a dog squinting his eyes to be polite. A dog that is comfortable and squinting his eyes to be polite might approach, whereas a fearful dog will keep his distance. There will be further differences with regard to body movement, as the comfortable dog will have a looser body and move with ease, whereas the fearful dog may seem frozen or stiff, showing little movement.

When interacting with a dog, you can squint your eyes ever so slightly to be polite; a slow blink can also be used. It is best to avoid direct eye contact by using peripheral vision and turning your head away slightly. A combination of this body language may be used to show polite intentions, especially towards a dog that is not at ease. It is always best to give any dog space and not approach. Read more about social interactions with dogs in this article: ‘How do you greet a dog politely?’

Since this article pertains to one area of the body, bear in mind the importance of observing the dog’s full body language and signals, as well as the context in which they appear, before attempting an interpretation. There may be different interpretations, depending on the combination of full body language observed.

Here are a few examples of situations where a dog may offer shortening of the eye:

A person is sitting on the ground and taking photos of the dogs in the park. One of the dogs, a retriever, is familiar with the person. The retriever spots the person with the camera and decides to approach them, as all the dogs he has been socializing with have moved on. He approaches with a loose flowing body, trotting up with his tail at about level with his back, giving a slow, sweeping wag. There is a slight curve in his body on approach. He lowers his head ever so slightly; he gently squints his eyes slightly on approach. His ears are relaxed and at the side, and his mouth is open and relaxed with a slight panting tongue. The retriever is at ease and trying to be polite by approaching with the slight curve of his body and shortening of the eye.
While sitting on the ground, a dog is being scolded by a person. As the person raises her voice, he pushes his ears back tightly against his head and squints his eyes shut. His mouth is closed and he gives a few careful lip licks. He remains still and occasionally opens his eyes slightly, giving a few blinks before squinting his eyes again. As the scolding tone of the person’s voice eases off, the dog wags his tail low to the ground, quickly from side to side. The dog is offering appeasement in response to his guardian’s raised voice and is trying to communicate he means no harm.
A dog is sitting near a group of people on the grass in a park. One person, who is sitting quite close, is looking at the dog and giving direct eye contact. The dog averts the gaze of the person by turning her head ever so slightly away and softening her eyes by squinting. The dog is trying to give a non-confrontational response to the direct eye contact.

These are just a few examples; there may be many more. Start observing to see if you can notice any squinting or shortening of the eye in different contexts. As discussed below, interpretations such as the above examples should not be attempted without careful observation and consideration of all aspects of the situation.

A few notes to consider when observing dog body language:

Observation before interpretation

Interpretations should be offered only once you have observed the complete interaction and taken note of the wider picture. To offer an unbiased interpretation of the body language, observe and take note of the situation, taking into account the dog’s whole body, the body language signals and environment first before offering an interpretation. List all the body language you see in the order that it occurs; try to be descriptive as possible without adding any emotional language. For instance, saying a dog looks happy is not descriptive and would be seen as an interpretation rather than an observation.

You could however list what you observe: ears to the side, eyes almond shaped, slight shortening of the eye, mouth open, long lips, tongue out, body moving loosely, body facing side-on, tail wagging at a slow, even pace at body level.

From the observation I could interpret that the dog seems relaxed or comfortable. I still prefer to say relaxed rather than happy, as I feel you will truly never know exactly what the dog may be feeling on the inside emotionally. It is quite likely the dog may be feeling happy, but I prefer to comment on how the dog is behaving in response to the situation rather than presuming internal emotional states.

The importance of viewing body language within context

Interpretations can vary depending on the context. It is possible for certain body language to be used in different contexts and have subtle differences in meaning within those contexts. Individual body language signals should not be observed in isolation; the wider picture should be considered. Take note of what the dog’s body as a whole is saying. Keep in mind each dog is an individual with varying skills and experiences. What may be typical for one individual may not be for another. In order to observe body language in context, consider the following: the situation, body language signals, the body language expressed by all parts of the dog’s body, the environment, and the individuals involved. It is worth noting how the body language changes with feedback from the environment or the other individuals interacting.

My vision is to create a community of dog guardians who share their observations and interpretations of their dogs’ silent conversations. Hopefully, these experiences and stories will provide some insight into dog communication, which is often overlooked by the untrained eye because it is unfamiliar to humans. We are accustomed to communicating mainly with sound, so we are not attuned to the silent subtle gestures and body language used by dogs to communicate. If you take the time to observe, you will start to see these 'silent conversations' going on around you. My dream is for dog communication to become common knowledge with all dog guardians and as many people as possible. Surprisingly, there are still some professionals working in various dog-related careers who are uneducated about dog body language. Greater awareness of how dogs communicate will help to provide better understanding and improve the mutual relationship between dogs and humans. This will promote safer interactions between our two species and hopefully remove some of the expectations placed on dogs within human society. I would like dog guardians to feel empowered with their knowledge of dog communication so that they can be their dogs’ advocates and stand up for themselves and their dogs when it really matters.

Eyes – Pupils Dilated – Dog Body Language

Eyes – Pupils Dilated – Dog Body Language

With regard to observing dog body language, pupil dilation can provide vital clues as to the dog’s emotional state. Dilation of pupils can occur in low light conditions to assist with vision by allowing more light into the eyes. In other instances it occurs as an involuntary response due to the sympathetic nervous system being activated. Dilated pupils can indicate the dog is feeling some form of stress*, fear or arousal.

Pupil dilation can be a subtle change in size, and at other times it is overt, with the pupils appearing so large that hardly any iris eye colour is visible. One cannot just observe one body part, such as dilated pupils in isolation; the whole body, including body language and signals, should be observed in their totality in order to offer a complete interpretation. Sometimes the body language signals, paired with dilated pupils, can be very subtle, so I like to pay attention to the dog’s body movements as part of the observation. The movement seems to be at two ends of the spectrum: At one end, the dog may appear frozen or still and not move much. At the other end, the dog may seem jittery and unable to be still, to the extent that he reveals noticeably tense muscles and muscle twitches, which may be caused by a build up of adrenaline in the system, activated by the sympathetic nervous system.

Caution is advised when trying to observe a dog’s eyes. It is worth paying attention to being polite by avoiding direct eye contact and any prolonged staring, especially if a dog is already experiencing some discomfort. Give the dog space, and use your peripheral vision to observe without giving direct eye contact. You can squint your eyes and blink if giving short amounts of eye contact. It is also advisable to turn your head away ever so slightly and keep your body turned side-on to the dog, so that you are not adding to the pressure the dog may be experiencing with your body language.

Here are a few examples of situations where a dog’s pupils may appear dilated:

This is an observation of a dog showing fear in a vet’s examination room. The dog is panting heavily, with the tongue starting to look spatulate. The eyes are wide, the pupils dilated, and he keeps scanning the environment. As he pants, his mouth is wide open, and there are quite a few deep creases forming around the corners of the mouth, under the eyes, and on the brow area. The ears are held to the side; on occasion they move from the side to the front to listen to sounds in the veterinary rooms. He seems restless and sits on the floor before pacing around the room with tail tucked and body slightly lowered. With his tail still tucked, he walks over to the door and sniffs underneath it. Then he paces back near to his guardian. After stopping for a while, he continues pacing around the room whilst panting.

On her blog, Eileen has shared informative examples of her dog, Clara’s, facial expressions when visiting a vet. The photos illustrate clearly how stress is displayed in the facial features. There is also a comparison of Clara’s facial expressions when relaxed, as opposed to stressed. In the photos that illustrate the stressed expressions, the pupils appear dilated. For excellent photographic examples of dilated pupils click here.

A dog is very excited to go out for a walk. When the guardian walks into the room with the leash in hand, the dog starts running around the room, wagging his tail very fast, and jumps up at the person. The dog is now panting and his pupils are heavily dilated. He jumps up some more, making it difficult for the guardian to clip the leash on. With his eyes wide, the dog briefly runs around the room again, and then he does a quick shake off. The dilated pupils, panting, fast movement, and inability to stay still indicate the dog is over aroused due to excitement.
At a shelter, a volunteer returns to the room with a dog. The dog starts panting the minute she is back in her room. Her pupils become heavily dilated, and her eyes appear wide. The areas under her eyes look puffy, and muscle tension causes deep furrows start to show on her face. She paces around the room for a few moments, then chooses to sit. Her ears are held to the side but move slightly forward, and her mouth closes for a moment as she listens to the sounds coming from the shelter corridors. She continues to pant and then gives a big yawn. This is an observation of a dog at a shelter becoming stressed when she returns to her room and is left there on her own.

These are just a few examples; there may be many more. Start observing to see if you can notice pupil dilation in different contexts. As discussed below, interpretations such as the above examples should not be attempted without careful observation and consideration of all aspects of the situation.

What is meant by stress*?

When I mention stress, this does not necessarily imply negative emotion. I mean stress in the physiological sense. So certain body language signals can mean the dog is feeling some sort of emotional discourse. This discourse could range from positive to negative emotion. Both excitement and fear could have similar effects on the body, with various hormones being released and activating the sympathetic nervous system. The dog may be feeling uncomfortable/fearful or it could also be excited about something. When analyzing stress in body language, it is worth noting the frequency and intensity of the various body language signals.

Eyes – Hard Eye – Dog Body Language

by Martha Knowles | Nov 11, 2018 | Dog Body Language, Eyes - Dog Body Language

Eyes – Hard Eye – Dog Body Language

The term ‘hard eye’ in dog body language refers to situations where a dog gives direct eye contact, characterized by an intense hardened, fixed, glassy stare. Eye contact is not polite in dog communication and is used for the purpose of a warning or as a direct threat to another party, with intent of further action should the party not heed the warning by moving away.

Hard eye can be difficult to describe; there is a lack of analytical language to convey precisely how the eyes appear. If you have been on the receiving end of ‘hard eye’, it is something that you will sense, however difficult it is to put in words. The eyes seem to glaze over and become colder, and there is a definite change in their appearance, as well as a lack of warmth.

Hard eye is normally displayed along with other body language: the eyes will appear large and wide, the dog’s mouth may close, or the dog may already be displaying an agonistic pucker (showing teeth). Tense areas may be apparent on the face, with the skin pulled back or deep furrows showing in areas. The ears may be positioned slightly to the side or moved forward with tension, while the whiskers may look flared or appear to be pushed forward. The dog’s body might orient towards the party receiving the stare, and the whole body could seem tense. Most commonly, the dog will appear still and frozen. A hard stare and freeze may be the last warning before further escalation or even a bite.

The hard stare and freeze can be prolonged in some instances, but in other situations it may occur so quickly that it is missed, with people not realizing a warning was given before a bite. There is a quick glaze, along with a freeze of the body, and, within seconds, a fracas breaks out between two dogs, with the human not realizing which dog instigated it with a stare.

This is why it is important to consider how you use eye contact when interacting with a dog, especially one that is unknown to you. If you wish to be polite, it is crucial to try to build trust by avoiding direct eye contact – especially in the first interactions. As well as being aware of your eye contact, make sure your body is positioned in a non-confrontational manner by turning your shoulder away, with your body facing side-on to the dog. It is polite to avoid staring by turning your head away slightly, using your peripheral vision to observe the dog. If you do give a little selected eye contact, do so for short periods with slightly squinted eyes, and you can also include some slow blinking. Most dogs have grown accustomed to receiving direct eye contact from humans, especially from family members with whom they may feel comfortable. Some dogs may not respond to direct eye contact favorably, especially from strangers, and may display their fear by barking or lunging at the person.

Here are a few examples of situations where a dog may display a hard eye:

An adult dog is lying down on the ground, chewing on a toy. An adolescent dog is playing around with another toy across from the older dog. He throws his toy around clumsily, dropping it near the adult dog’s feet. The adolescent dog playfully stumbles over towards his dropped toy. The adult dog is wary of the younger dog coming closer and possibly attempting to take his toy instead of the one dropped, so he keeps the toy in his mouth, quickly stops chewing, and freezes. His ears go ever so slightly forward, his eyes become wider, and he gives a direct stare towards the adolescent dog, whilst keeping very still. The adolescent playfully paws in the direction of the adult and lets out a playful huff. Remaining frozen, the adult continues to give eye contact. His nose creases and he shows some of his front teeth. The adolescent averts his head slightly, does a lip lick, and turns away to pick up another toy, which is on the floor a little further away.
A person is standing between a couple of dogs and giving each of them attention. Another dog approaches the group. One of the dogs receiving attention freezes for a second. Whilst orienting towards the approaching dog, he gives direct eye contact with a hard stare. This happens in an instant. The person giving attention to the dogs is standing behind the dog that is giving the stare, and she does not realize this is occurring. Unfortunately, by engaging with the approaching dog, she continues to encourage him to come closer. The dog that is giving the stare lunges and snaps at the approaching dog, which reacts and snaps back. All of this happens so quickly. The person shouts at the approaching dog, whereupon both dogs move away and do a shake off.
There are a few dogs hanging out in a dog park. One of the dogs, a small terrier mix, prefers to not interact with the dogs running around and chooses to lie down in the shade near where the people are sitting. After a few minutes, a poodle mix decides to walk towards the terrier, which is still lying in the shade. He approaches the terrier from behind and gently scents his rear end and back. Although the terrier remains lying down, his body stiffens, his head rises slightly, and his ears move a little to the side. He becomes very still and his eyes seem wide. The terrier does not turn to look at the dog sniffing him but remains still. The poodle now carefully walks in a slight curve to the front of the terrier. With eyes somewhat squinted, and ears a little back, he stretches out to carefully sniff the terrier around the face. The terrier turns his head away slightly; his eyes remain wide and have a hard appearance, and a bit of ‘whale eye’ is visible. The reason for the appearance of ‘whale eye’ (the sclera or whites of the eyes becoming pronounced) is that the dog is trying not to give direct eye contact but does not feel comfortable taking his eye off the subject that is causing him concern. The poodle continues to air sniff near the terrier’s face. The terrier still frozen, and revealing hard eyes, now lifts his lip, showing some teeth. The poodle does a head turn and lifts his paw, then decides to carefully turn and walk away from the terrier.

These are just a few examples; there may be many more. Start observing to see if you can notice ‘hard eye’ in different contexts. As discussed below, interpretations such as the above examples should not be attempted without careful observation and consideration of all aspects of the situation.

Eyes – Almond shaped – Dog Body Language

Eyes – Almond shaped – Dog Body Language

‘Almond-shaped eyes’ is a term used to describe the eyes of a dog in a relaxed and neutral position. The term ‘soft eyes’ may also be used and implies almond-shaped eyes. Both terms are quite self-explanatory. For instance, if a dog is alert, anxious or uncomfortable, the eyes will appear larger and rounder due to muscular tension in the face pulling the eyes open wider. If there is no tension in the face, the eyes naturally should appear slightly squinted and almond shaped. The gaze of the eyes should appear soft.

Along with soft/almond-shaped eyes, other parts of the dog’s body will indicate that the dog is relaxed. There should not be any tension around the eyes or on the face. The eyes may blink. The dog’s mouth may be slightly open, the ears could be slightly to the side and neutral, the body should be loose and moving fluidly.

Here are a few examples of situations where a dog eyes may appear almond shaped:

A dog is lying on the grass in the park. There is no tension in his body; he seems relaxed and his tail lies loosely on the ground, following the curve of his back. His eyes are neutral and almond shaped, and his mouth is slightly open at times. His ears are relaxed and to the side, and occasionally they move around to listen to the sounds in the park. He slowly dips down his head and sniffs some of the grass in front of him. As his guardian approaches, the dog looks up at him, slightly squinting his eyes. His ears move back slightly, and he thumps his tail on the ground in a slow, circular pattern.
A dog is walking around in the park, off leash. His body looks loose, and he moves easily as he strolls around. His eyes are almond shaped and his ears are to the side. His mouth is open, his lips look long, and his tongue is hanging out, as it is a warm day. Occasionally, he curves and dips his head down to sniff the grass, his mouth closing as he does so. He curves round to watch some dogs greeting each other in the distance. Stopping, he lifts his head a bit higher and closes his mouth. His ears go slightly forward, and his tail pauses and is held level with his back. The dogs in the distance greet curve around each other and go their separate ways. The dog curves away, moving in a loose flowing manner, with his tail wagging slightly from side to side. He continues to walk in the opposite direction and occasionally dips his head down to sniff.

These are just a few examples; there may be many more. Start observing to see if you can notice almond-shaped eyes in different contexts. As discussed below, interpretations such as the above examples should not be attempted without careful observation and consideration of all aspects of the situation.

Importance of allowing your dog to sniff

by Martha Knowles | May 14, 2018 | Thoughts & Reads

Importance of allowing your dog to sniff

I peek out the front door to check on my dog, who is sunning himself in his favourite spot in the sun. He is lying on an old moving trolley, since repurposed to give him a boost up to the sunrays, which don’t reach the ground at this time of morning. As I stick my head out the door, he lifts his nose, and I can see his nostrils gently flare in and out as he recognizes I am close. He does not see me with his eyes, as they are squinted shut due to the sun, but he sees me with his nose.

There are many more examples of my dog using his nose to see. When I return from the shops, and we greet enthusiastically, my human tendency is to reach out and touch to say hello, but he ducks away, preferring to sniff my hands first to see where I have been. (If you have not already read about the human as opposed to canine perspective of greeting, it is worth reading ‘How do you greet a dog politely’). When I return from volunteering at the dog shelter, he sniffs my shoes and clothes carefully. I get the full pat down with the nose. If I offer him something, whether it is an object or food, he does not use his eyes to examine the item further; he sniffs it.

On one occasion, when out on a walk with my dog, he stopped, hesitant to go further. I surveyed the pavement ahead. It seemed clear. I thought he was being overly sensitive and encouraged him to continue. As we passed the parked cars ahead, hiding behind the wheel of the last car was a cat. I felt very foolish. My dog was right – there was something ahead! He had seen it with his nose. I should have listened. Being human, I had immediately dismissed what I could not see with my eyes. On another occasion, he started sniffing the ground very attentively, seemingly following a trail back and forth, as he narrowed in on the direction of the scent trail. Looking ahead to see what had taken his interest, it was easy for me to quickly spot a scattering of nacho chips that had been discarded on the pavement. This time my eyesight won out against my dog’s nose, and I was able to divert him away.

Even with these simple observations, it is apparent how often my dog uses his nose and scent to make sense of and navigate his environment.

It is understandable why the use of olfaction may be the predominant sense for dogs. It is estimated that dogs have 300 million olfactory receptor cells; in comparison humans have about 5 million. Dogs have the ability of smelling with each nostril on an individual basis, allowing them to distinguish the direction of the scent. The slits on the side of the nose allow for the old air to exit at the same time as the dog is breathing in new air through the nostrils, allowing the dog to take in scent continuously. The air is separated and passes through an area at the back of the nose that has a labyrinth of scroll-like bony structures called turbinates. The air is filtered through the turbinates for olfaction, while some of the air follows a separate route down the pharynx for respiration. The air that humans take in for respiration and scent is not separated, going in and out with the air that we smell. Additionally, dogs have a secondary olfactory organ called the vomeronasal organ that allows dogs to detect pheromones and non-volatile chemicals. There are times where you can spot the dog using his vomeronasal organ, as he will display a tonguing response. The dog may chatter his teeth or drool a bit at the mouth as he deciphers the components of the scent. To interpret all this information, a larger percentage of the dog’s brain is used to process scent, with the olfactory bulb taking up more area of the brain than it does in humans. The dog can detect smells at concentrations of 100 million times less than our noses can detect.

In Alexandra Horowitz’s book, ‘Being a Dog: Following the Dog Into a World of Smell’, she gives an example of scientific research to test scent thresholds of detection dogs. One of the tests was how diluted an odour could become before the dog would struggle to detect the odour. The scent of amyl acetate (smell of banana) had to be distinguished from non amyl acetate canisters. The dog kept finding the scent until it was diluted to the equivalent of a couple of drops of amyl acetate to one trillion drops of water.

It is estimated that dogs have 300 million olfactory receptor cells; in comparison humans have about 5 million.

The following Ted-Ed video lesson by Alexandra Horowitz gives a good summary of the dog’s sense of smell and why dogs are physically able to process scent so efficiently. For an in-depth look at how dogs perceive the world with their noses, it is well worth reading Alexandra Horowitz’s book, ‘Being a Dog: Following the Dog Into a World of Smell’.

Imagine visiting an art gallery if every time you attempted to look at a painting, you were forced to move along and had your eyes covered, missing the chance to get a glimpse of the painting. How frustrating an experience would that be? As humans, we do not have the same level of perception and therefore discount dogs’ levels of sensory perception far too many times, especially when giving them opportunities to interact with the environment. Too often I have seen guardians impatiently yanking their dogs away if the dog stops to sniff even for a moment. I have observed dogs that are walked obediently to heel and not permitted to stray to sniff, dogs walked with equipment that does not allow them to dip their noses down or move their heads or bodies with ease, or walks that are carefully curated from a human perspective, where the walk is a quick march for exercise purposes and stopping is not tolerated. The mental stimulation from sniffing and exploring can be just as tiring as physical exercise.

If my dog responds to an environment in a manner in which he is comfortable to investigate it – in an in-depth manner with calm sniffing – this indicates that the walk is going well and the environment is suitable for him. If my dog is pulling, moving erratically and choosing not to engage with the environment by sniffing, this is a telltale sign that he is not coping for some reason. So sniffing calmly and engaging with the environment can give clues as to the internal state of your dog. A good walk for my dog would be one in which he meanders with a calm, loose, slow-moving body, taking his time to stop at various spots to sniff and investigate. To do so, the leash needs to be long enough for him to move comfortably, and the equipment he is wearing should not hinder him from being able to reach the ground with his nose easily. The choice of walk should be individual for each dog; certain environments or times or the duration of a walk can be too stimulating for some dogs. A dog may not have the appropriate skill level or coping skills for a particular environment, or the dog’s stress level may be too high to cope with a particular walk.

How your dog engages with the environment by sniffing, and in which context he does so, can give vital clues as to how comfortable your dog is feeling and if he is coping within an environment.

There is another important reason to pay attention to your dog’s sniffing. On certain occasions, sniffing plays a part in how dogs communicate. If you have not already read the dog body language article about sniffing, you can read about it here.

The dog may stop to sniff as a calming signal or negotiation. For example, a dog may use sniffing the ground at a distance in the beginning stages of approaching another dog. A slow non-direct approach is polite, and it gives each party the opportunity to negotiate at a distance. In another context, sniffing could be used as a way to defuse a situation; one dog may walk away sniffing the ground, encouraging the other dog to mirror him, defusing the interaction.

Depending on context, sniffing the ground could also be displacement behaviour or a stress response. If the dog is unsure of something ahead, he may slow and start sniffing the ground, showing he may be feeling conflicted. It is vital to allow your dog to express himself and to observe your dog’s body language so you can offer support in such situations.

I mentioned an example of when my dog chooses to sniff the ground as displacement when he feels uncomfortable, in this article: ‘Considering the effects of walking or running straight towards a dog’.

The body language that occurs when a dog starts sniffing due to displacement can be subtle. It is crucial to observe changes in the environment, noting the dog’s whole body and body posture, as well as movement and body language signals. For instance, a dog may see something ahead, pause, and then subtly curve his body away from the object that is causing discomfort. He may then do some displacement sniffing. It is worth observing how he sniffs; some displacement sniffing may seem less focused than when a dog is actively investigating a scent. In other instances, it can seem out of place, as the dog suddenly finds a spot to sniff intently. The dog may use the moment of sniffing as a surreptitious way of surveying the environment, so it is important to observe where the gaze of the eyes falls. The dog may also move his ears, perhaps to the side slightly, in order to use his other senses to gather further information. One should pay attention to the subtleties.

Scent is the predominant way in which dogs make sense of their world. Sniffing is vital to the way dogs gather information and interact with their environment. At times, depending on the context, a dog is not just sniffing a scent; he is communicating. What he is communicating can vary according to the circumstances, so it is worth paying attention in order to be a supportive partner. Allowing your dog to interact fully with his environment and express himself with ease ensures a stronger, mutually connected relationship between dog guardian and dog.

My vision is to create a community of dog guardians who share their observations and interpretations of their dogs’ silent conversations. Hopefully, these experiences and stories will provide some insight into dog communication, which is often overlooked by the untrained eye because it is unfamiliar to humans. We are accustomed to communicating mainly with sound, so we are not attuned to the silent subtle gestures and body language used by dogs to communicate. If you take the time to observe, you will start to see these 'silent conversations' going on around you. My dream is for dog communication to become common knowledge with all dog guardians and as many people as possible. Surprisingly, there are still some professionals working in various dog-related careers who are uneducated about dog body language. Greater awareness of how dogs communicate will help to provide better understanding and improve the mutual relationship between dogs and humans. This will promote safer interactions between our two species and hopefully remove some of the expectations placed on dogs within human society. I would like dog guardians to feel empowered with their knowledge of dog communication so that they can be their dogs’ advocates and stand up for themselves and their dogs when it really matters.
