A man blows on a puppy. A common cause of dog aggression — dominant nature and desire to take a leading position. The victims of such dogs often become family members, which she believes in the hierarchy below them. Usually such a dog considers only one person to be the leader or there is no authority among family members for it at all.
Innocent attempts to push the dog off the couch, step over a dog lying in the doorway, try to get her if she does not “sit” command, and the dog shows teeth, growls or bites. The dog considers herself the head of the pack and I’m sure that people do not deserve the status of leaders, to obey them.
