my toy poodle mix pulled too. she obviously didn't pull ME (lol) but just like carrieB's dog, she chokes herself. we got her a harness and the first day it worked great! she still pulls a little but not nearly as much. it was a cheaper harness, but it still works. i would go out and get a puller harness. he may still pull a little so then you can teach him like orangutango does. i think that will work well. Good Luck!!
