Hard to say. I trained my last one to walk at heel but he would always start pulling as we started to get home. As soon as he could see it he wanted to pull.
But I did have him trained to stop and sit any time we had to cross a street. The few times he would get out, he wouldnt cross the streets and we’d find him around the block.
He had zero interest in other dogs. Whenever I took him anywhere, he just wanted to be a complete lap dog. He’d whine if he wasn’t on lap sitting. That said, whenever we walked past other people or dogs, I’d keep him on an extra short leash incase the other dog might try to do anything.
