My boy is eight months old and, we have attempted two training classes, the first one he was too young for, the second one was age appropriate but within a half hour at the first off leash puppy play my boy tried to start a fight with ten puppies.
He has a boxer brother at home and a Chessie neighbor and has never show any signs of aggression.
This weekend a little mini schnauzer came to visit and my dog immediately tried to pin him, he pinned him about 50 times in a few hours span. I use a gentle leader and it does help.
What makes him want to do this?
