Hello, This is my first post and glad to find a forum like this to discuss doggy issues.
Three year old mastiff (180 lbs), who in the last few months has become aggressive with people coming home and while on walks around the block
. Otherwise on trips to public places like Petsmart (where he has gone for training before), he is the sweetest mastiff ever
Need a trainer to come home to train. Can anyone recommend one in the Mississauga area?
