live with my mom. There is this guy with a pit bull who does work on our house sometimes. It usually sits in his car, but the dog wanted out today. So the dog was running around, and I noticed it had a pronged collar on. I acted like I didn't know what it was. I said "what kind of collar is that?". He said it's a pronged collar. He said that its usually just used for training, but he keeps it on because when they go in public, the dog pulls a lot, and the collar makes him not want to pull. I dont know if he keeps it on him 24/7 or not. I really didn't want to get on his ass, because his son and mother recently died, and he's been going through a lot.
