When out walking with your dog off the lead, keep a small plastic pot containing cat biscuits. As you call your dog to return, shake the pot, when your dog returns to you, reward him/her by feeding a couple of biscuits. This really helps the dog focus their mind on returning to you.

How can I teach my pitbull\chow puppy to come when I call him?
How do I call my dog and get her to come? Sometimes she comes, but other times she just runs away.
