When leaving the kennel, the puppy will transfer the vital attachment that he had for his mother, to a member of the family.
This is usually the one who spends the most time with the puppy right out of the kennel. This bond will evolve and be influenced, after detachment and puberty, by sexuality and the hierarchical order that will be established. In adulthood, the dog will be attached to people who dominate him. They are his guides, those on whom he can rely, because they will take care of his needs.
The dog is programmed to follow these people because they are best able to ensure its survival, so some dogs may want to follow and go with people other than their owner. It depends on their sensitivity but above all on their hierarchical position.
The dog is above all "faithful" to the dominant.
