Teach “let go.” If the key to teaching a dog to like a toy is to make it exciting, then the key to teaching her to let go of the item is to make it uninteresting. Keep the toy in your hand but make sure it’s absolutely still, as though it’s in a vise. Also, act bored and dull, as though you couldn’t care less that your dog is pulling on the toy. Don’t look at her, and certainly don’t move the toy in any way. This may take a few seconds or minutes. Be patient. Eventually, your dog will become bored with the toy and let go of it; the split second she does, tell her “Yes!” and give the toy back to her as a reward for proper behavior.
