Aggressive St.Bernard pup
(Winnipeg, Manitoba )
I have a 7 month old St Bernard pup that has become very aggressive to other dogs and some people like children. He is a puppy but he is over 85 pounds so he is not the size of a puppy just the brain of one. He is very good aggressive and toy aggressive. I have 4 other dogs that he feels he can attack when he wants and unfornately they surrender to him. He was in puppy class since he was 4 months old and then went to the second level and that is when he started attacking other dogs in the class. I was told to put him on a gentle lead but when the trainer went to adjust it he lunged to bite her. I am scared and annoyed at what to do. Please if you have any help I would greatly appreciate it.
