Snuggle Puppy is not intended to be chewed on. When your dog is initially exposed to Snuggle Puppy, keep a tight eye on him. Please remove Snuggle Puppy away from your dog if you see them nibbling on it or attempting to open the Velcro pouch in the tummy. Remove the heat pack and heartbeat from Snuggle Puppy and reintroduce it to your dog without them. Continue doing this until your puppy understands that if they attempt to chew on Snuggle Puppy, their companion will be taken away. If your pet ingests the contents of the heat pack by mistake, contact your veterinarian right once.
