While other universities focused on the social connection of dogs with humans.  In this task, the dog was given a problem-solving test, which included trying to reach the food.  The length of time the dogs looked at the scientists was measured.

 The dogs were separated into two groups depending on their breed - the first group consisting of breeds that are genetically closer to wolves such as "Akita" and "Husky", and the second group consisting of other breeds genetically far from wolves (Rott, Pitbull).

 According to the results, the dogs in the first group looked at the scientists less often than the dogs in the second group during the problem-solving task;  This indicates that they were less closely related to 

humans.
