Ok so I have a 11 week old American Bully named Boats that I got when he was about 6 weeks old. The first 2 weeks I got him we would go on walks and jogs and he would have the same style harness and exact same leash I TRY to walk him on now. But after the 1st two weeks he all of a sudden stopped wanting to walk, and now he just holds his ground, I was told by my vet just keep trying which it's weird he will walk anywhere else with nervousness and a little hesitation but at the house he basically has to be drug to leave the front yard. My vet said let him drag the leash around the house which I do now and he doesn't even bother it nor seem like he even notices it, but he won't walk out of the house and off the front lawn. Idk what is causing the behaivor, a neighbor who also has a Bully said hers did the same and she got him a choke collar and forced him to walk and it helps with the training, I don't want to do that unless I have to, I love my Puppy I don't want him to be in pain. Any suggestions?? On Monday he will be 3 Months
