To begin, arm yourself with a VERY tasty treat. Gently open your dog’s mouth and place the treat inside. Immediately, close your dog’s mouth and walk away. Your dog’s reaction might be “What the—-” and then a sudden “Oooooh, yummm!!” This will make the next gator-mouth a little easier to do. With time and repetitions, your dog should be happy to have you open their mouth. For greatest impact, the treat needs to be high-value and novel. Dogs generally appreciate a chunk of stinky old cheddar or a hunk of meat but experiment to find your own dog’s favourite.
