Dogs will use eyes to express moods, and we love dog's squinting, this is usually a positive sign of contentment, joy and happiness. A confident socialised dog, during dog to dog induction will squint whilst gazing elsewhere.
Some dogs display a "submissive grin" or "smile". This is also a gesture where a dog shows his front teeth, but a smiling dog is doing just that. He usually shows a lowered head, wagging tail, flattened ears, a soft body posture, and soft, squinty eyes along with those teeth.
Most experts agree dogs smile in response to the human smile. Dogs seem to smile more when relaxing, playing, feeling content or greeting someone they know. Dogs don't smile in response to a joke, but they may smile in response to you. Usually, when a dog smiles it is known as a submissive grin.
Dogs may also smile when they're feeling guilty, or when you're trying to get them to do something they don't want to do, like take a bath. If they're doing this submissive grin when they've done something wrong, it's because they want to avoid getting in trouble or a hostile confrontation with their owners, Haug says.
A stressed smile is another way to show a tempered version of the submissive grin. Usually, a closed-mouth smile shows that the dog is apprehensive and stressed in their current situation, especially if they cower away or flatten their ears.
Warning About Dog Smiles
You may think that their grin is a sign that they are happy but in fact they are trying to indicate that they don't like something and are feeling stressed. The worrying thing is that stress in dogs can very quickly escalate into aggression and biting.
Can Dogs Really Smile? Most behaviorists don't really consider a dog “smiling” to be a true grin in the way we think about a human smile. Many canine expressions can be seen as a “smile,” including wide-mouth panting, relaxing with their tongues out, and submissive grins.
Possibly the most common “grin” from a dog, is the submissive grin, so named because dogs do it when trying to “appease” another dog or person. In this pose, the dog lifts his upper lip up to reveal his front teeth with a closed mouth.
The open-mouth smile is often used by celebrities to invoke a sense of closeness with others. This smile conveys a care-free and happy attitude and mimics the facial expression of a person laughing.
Experts in dog behavior believe that, in general, dogs do not like being embraced. However, every dog has a unique personality. Some may dislike hugs more strongly than others, and some may actually adore them. The closest thing our furry family members do to a hug is something referred to as 'standing over'.
Both tooth displays and smiles reveal the upper teeth (and sometimes the lower teeth), but in contrast to tooth displays, smiles happen quickly and are subtle. The upward movement of the lips away from the teeth is often slight, and the retraction rarely lasts more than a second.
Has your dog suddenly begun squinting, but only on one side? This is probably not a wink of affection. It may have developed an open sore on the clear protective layer covering its eye. These types of wounds are called corneal ulcers, and are a very common cause for squinting and discomfort in dogs.
But it is unmistakeably doggy. Canines don't sweat from skin pores like humans do, but they do perspire from their paws and hair follicles. They also produce oils that are essential for their skin and hair. Then there are the glands in their ears, which release a lightly yeasty scent.
If the other dog is on his back, the dominant dog might stand over him. In direct contrast, submissive body language broadcasts, “Don't hurt me!” or “I am not a threat!” The dog wants to make himself appear as small as possible. The body may be lowered, even to the ground. Ears are back.
Often the submissive grin invites interaction from others, but it's also possible that your dog is trying to increase distance between herself and others if she feels threatened. It's likely that your dog has continued “smiling” at you and your family because it's gotten her a lot of attention in the past.
Instead, they're smiling because they are calm and relaxed and, because of that, one could venture that your pet is happy. Similarly, some dogs will appear to smile if they are showing submission to their human counterparts. This relates to the dog being in a relaxed muscular state.
The television affects every dog differently.
While it's generally OK for dogs to watch television, the colors, sounds and content can make some dogs feel anxious.
Licking is a natural and instinctive behaviour to dogs. For them it's a way of grooming, bonding, and expressing themselves. Your dog may lick you to say they love you, to get your attention, to help soothe themselves if they're stressed, to show empathy or because you taste good to them!
Good news: dogs can be ticklish! Many dogs enjoy a good tickle on their paws, ears, and back. However, it's important to remember to tickle gently and that your dog might not enjoy themselves as much as you.
So if you catch yourself grinning from ear to ear thanks to all the benefits you get from your pup, rest assured that Fido is feeling the love, too—literally! Studies show that smiling at your dog can boost his or her levels of oxytocin, also called “the love hormone” for its role in building attachment and trust.
Science proves that part of the canine brain is associated with positive emotions and they do, indeed, feel love for their human companions.
If your dog follows you around it means they love your company, and you could also have a stage five clinger on your hands. ;) Likewise, leaning on you, wanting to sleep in your bed or in the same room as you, or snuggling with you are all good indicators of your dog's affection for you.
