Given the lack of words, on many occasions we use the facial expressions that our furry friends give us in search of understanding what they want to communicate to us in order to meet their expectations and make their life more peaceful in our home.

In this sense, you have surely come across having perceived a slight smile from your dog, which we see as an unmistakable sign of happiness, but far from it, a trainer wanted to warn us about it so that we take care of our pet from best possible way.

According to the trainer Pol Grau in his Tiktok profile, the “smile” that we perceive as a facial expression in our dog is usually the opposite, he may try to calm down or relax, which may mean that he is overwhelmed, stressed or has received some emotional impact. .

Despite the dog trainer’s explanation, social networks do not quite accept what he says and have opened the debate on whether everything he says is true, with statements such as “the facial structure of dogs does not allow them to change their expression” or that it could be “positive emotional impact, my dog ??gets like this when she hasn’t seen me in a while.”

Yes, there are also those who appreciate this explanation in order to better take care of their canine companions, who are interested in canine psychology, and notice this type of behavior in moments of sleep, punishment or illness, in some cases.

Be that as it may, the video with the trainer’s explanation has gone viral and proof of this is the number of comments, which reach even more than the likes, and the fact is that the debate, far from being closed, gives the sensation of being more open than never.
