As we know, dogs show different behavior patterns among themselves, often showing different reactions to the same stimulus. This is what happens with TV; while some dogs completely ignore his presence, others remain attentive to every image he projects. This curious fact arouses all kinds of opinions among experts.
An example is the study carried out last year by a group of scientists from the Lyon Veterinary School, in France. Led by Dr. Dominique Autier-Dérian, this experiment demonstrated that dogs are capable of identifying other members of the same species, human beings, and even other animals, through the screen of the TV. For this, nine dogs were trained and presented with a series of images of different mammals, among which they recognized and regrouped other dogs within the same category.
And it is that as the professor of Canine Psychology indicated to the BBC Stanley Coren, from the University of British Columbia, all dogs are capable of watching television, although this is conditioned by certain factors. One of them is the way they assimilate the movement of the screen; their eyes detect up to 75Hz, while for humans a frequency of 60Hz is sufficient to capture movement. That is why dogs do not capture continuous movement on the television, but still images.
Also keep in mind the character of each dog. Not everyone is attracted to the same things. For example, they may pay particular attention to images of other animals on the screen and ignore all the rest. The same happens with the sounds that the television emits: they tend to respond to loud noises, barking, crying, ringing, etc. It all depends on the behavior and education of our pet.
