Hello. I was wondering if Any one else has to deal with a situation were the sweetest people loving dog totally freaks out with aggression towards other dogs? Our Olde English Bulldog is 4 years old. He went through obedience training but it was done in private lessons — beginner and intermediate!  I think private lessons where we made a mistake. I have had two rotor cuff surgeries and cannot walk him anymore by myself as he pulls badly and acts crazy. We walks along great until he sees another dog and then goes stupid.  Any suggestions? Please!
