I'm really hoping for some hints on getting my collieXkelpie to walk nicely on the lead
She is probably around 1 now, she was a rescue so we're not 100% sure how old she is. She is eager to learn; can sit, stay, drop, fetch and has good recall but pulls a lot whenever she's on the lead. We have a shortish lead as we were told she had a habit of chasing wheels but we've curbed that habit, and I wonder whether a long or extending lead would be better? I've read Positive Dog Training and one of the Cesar Milan books but she seems too excited to remember not to pull, we stop and she stands next to me but as soon as we move off she pulls. Help...please
