The original protocol was created by Dr. Karen Overall. I have modified it to be terrier-specific, quicker to train, and more fun for everyone! If you google “Dr. Karen Overall Protocol for Relaxation” her original will come up.
When treating on the bed, move towards your pup with a treat in your hand. Your goal will be to feed them a treat with almost no movement on their part. If they move, freeze (don’t jerk away) and if necessary, slowly move the treat away. Then try again. Repeat this until you can get the treat to the dog’s mouth with no moving around or jerking for the treat.
Do this consciously anytime they act too excited about the treats. Don’t add in the taking steps back etc. until this is going well.
