Hi I'm new here. I'm the proud owner of an American Bulldog named Tug. My husband bought him from a private breeder. His father was pure AB, but the mom was not on site at the time. We are now believing that it's possible the mom was an AB/Pit mix because though Tug has some AB features, he as Pit features as well such as his coloring. He's black with white chest and socks. Though i've read articles about there being black AB's and that they are a rare breed i have my doubts. He has many many AB personality traits and is an amazing dog. My only problem is getting him leash trained, he loves to walk but as his name suggests, he loves to tug and being 70 pounds of pure muscle he can be a handful. I want to be able to take him out to parks and such but sooo many people are scared of him. He's extremely loving but also extremely high strung when he's out in public and likes to jump. How do i deal with these things?
