Use redirection and yelps to teach your puppy that mouthing is never acceptable, even in play. Offer chew toys instead.
Biting and Mouthing
Ignore jumping puppies completely. Only give attention and treats when all four paws are on the floor to reinforce good manners.
Jumping
Ensure your puppy's needs are met to reduce barking demands. Reward quiet moments and disregard barking.
Demand Barking
Teach your puppy "place" and don't share food from the table or give in to begging behaviors.
Begging
Say "ouch!" dramatically and ignore nippy puppies briefly. Redirect their energy into a toy to chew instead of hands.
Puppy Biting
Prevent separation anxiety by gradually increasing alone time and keeping arrivals/departures low-key.
Separation Anxiety
Stick to a consistent potty schedule and always praise and reward desired elimination outdoors. Never punish accidents.
