Being very comfortable wearing an appropriate and well-fitted muzzle is a good training goal for any dog—particularly in situations where the dog may become worried or uncomfortable (think vet visits!). However, if a dog has never worn a muzzle or been made to feel comfortable with one, having one placed on her face abruptly could cause her to feel even more fearful.You can help prepare your (or your clients') pets to love the muzzle by building a positive association with it. In this video, the trainer is teaching the puppy that sticking his snout in the muzzle means cheese!
