Scientists continue to study dogs and their owners: this time they evaluated the expressiveness of the pets’ muzzles

In addition, mature – 2 to 7 years old – dogs seemed more expressive than older dogs. It also depended on the animal’s trainability.

According to the scientists, it is necessary to take into account the results of the study, as the relationship between humans and dogs continues to develop both from an evolutionary point of view and in the context of training and welfare of our brothers of the least.
