Redirect biting to an appropriate chew toy immediately
Stop play and withdraw attention when biting starts
Use a firm, calm “no bite” or “ouch” once, then disengage
Avoid rough play that encourages biting
Reward gentle mouth behavior with praise and treats
Provide plenty of age-appropriate chew toys
Make sure your puppy gets enough exercise and mental stimulation
Use short, consistent training sessions every day
Teach and reinforce “leave it” and “drop it”
Socialize your puppy with other well-mannered dogs
Avoid using hands or feet as toys
Stay consistent with everyone in the household
Crate or pen your puppy for short calm breaks if overstimulated
Seek help from a professional trainer if biting is severe or not improving
