Justin Silver Says: "What I usually do is grab a 30-foot leash for this, and I work on my come commands. I work on it outside and I start small. I start with a few feet and have the dog come with treats and toys that it likes.
I'll repeat the process. I'll have the dog come to me, have it sit and take a few steps back. Have it run to me, ask it to sit again and have it run to me, each time extending it further and further. Having a long leash is a really good way to do that. Using a long training leash is really the way to go."
