I recently took in an adult bull terrier about 4 days ago, he seems over weight. He was chained too a wall and was feed but wasn't walked. His previous owner only de wormed him once a month and has no vaccines ( dont worry we plan to vaccinate him) Up until now he only barks at night and has shown no sign of aggression ( thank god) only too another male bull terrier and my pit bull puppy. Kids have petted him and seems too tolerate kids. He doesn't mind strangers petting him. He even let me bathe him only haven meet for a few hours. His testicles are abnormally big since he was bitten by a spider before he was brought home. I have too give an antibiotic injection but im afraid of him. I took him in because i felt that he needed a better home, instead of where he was previously living and walking on his own feces. The previous owner said he was a very calm dog and even played with his kids and up until now like i said he has shown no sign of aggression he may bark at you, but my brother says its because his seeking attention, once you get near him and start petting him he doesn't bark. My brother is the one that walks him and plays with him. Advice on how too act and win him over if possible ? Im working with my fear of dogs, since i also just recently adopted a blue nose pit bull puppy that was living in a 2 room apartment.
