I have a really cool dog, his name is Bo. He's 3 and he's half lab half pitbull. I love him to pieces, but I have some problems with him. He was potty trained very quickly when we got him and learned all the basic tricks within weeks, and he was only 10 weeks old when we got him! Now, I've ended up with a very intelligent dog who prefers the indoors and is terrible at walking on a leash and he pulls. I want to be able to train him to the point where I can take him to a trail in the woods and not have him run too far from me. As soon as he sees another living thing outside, he wants to go play with it and he just yanks you with him. Does anyone have a similar problem and is there anyone with dog training experience who can help?
