This is a video of Kora, Aly's dog who is reacting to a piece of ham as a treat. She is a Great Pyrenees puppy that was surrendered to my clinic after being hit by a car. I repaired her fracture leg and adopted her myself. She started doing this chattering behavior only over treats she really enjoys. We gave her a piece of meat and she went absolutely crazy and foaming at the mouth. She has become viral over this behavior.
