Redirect biting to an appropriate chew toy immediately
Stop play as soon as teeth touch skin
Use a firm, calm “ouch” or “no” once, then disengage
Turn away or leave the room briefly after a bite
Reward gentle mouth behavior with praise and treats
Keep training sessions short and consistent
Avoid rough play that encourages biting
Provide plenty of chew toys and rotate them regularly
Make sure the puppy gets enough exercise and mental stimulation
Teach and reinforce basic commands like sit, leave it, and drop it
Socialize the puppy with other vaccinated, well-behaved dogs
Do not use hands or feet as toys
Supervise interactions with children closely
Crate or separate the puppy when overstimulated or tired
Seek help from a professional trainer if biting persists
