When Do Puppies Stop Biting? Teething Phase
It is the #1 complaint of new owners: "My puppy is aggressive!" Rest assured, your 10-week-old Golden Retriever is not aggressive. The AKC confirms this is completely normal—they are Teething.
The Timeline of Pain
8-12 Weeks: Needle Teeth
Puppies have 28 deciduous (milk) teeth. They are razor-sharp.
- Behavior: They explore the world with their mouth. Since they don't have hands, they "grab" your arm to play.
- The Reaction: If you pull away and scream, they think it's a game.
12-16 Weeks: The Fallout
The baby teeth start falling out. You might find rice-sized teeth in the carpet.
- Pain Level: High. Their gums are sore. They need to chew to relieve pressure.
6 Months: The Adult Set
By 6 months, all 42 adult teeth should be in. The biting should stop—IF you trained them.
How to Stop Biting (Bite Inhibition)
You cannot stop a puppy from biting, but you can teach them Soft Mouth.
The "Ouch" Method
- Play with the puppy.
- When teeth touch skin (even lightly), say "OUCH!" sharply and go limp.
- Stop moving. Be boring.
- Resume play.
- Lesson: Skin is fragile. Teeth end the game.
Redirect
Always have a toy in hand. Shove a rope toy in their mouth before they grab your ankle.
Best Teething Toys and Relief
Providing the right chew items during teething makes a massive difference. Frozen washcloths soaked in low-sodium chicken broth offer soothing cold relief on sore gums. Rubber Kongs stuffed with frozen peanut butter give them a productive outlet for their chewing urge. Avoid antlers, hooves, and hard nylon bones for puppies under 6 months, as their baby teeth can crack on these materials. Rope toys and braided fleece are excellent because the fibers act like dental floss between teeth.
What NOT to Do During the Biting Phase
Never hit a puppy's nose or hold their mouth shut as punishment for biting. These methods create fear, not learning, and can lead to genuine aggression later. Avoid playing tug-of-war with your hands or wrestling, as this teaches them that human skin is a toy. If children are involved, teach them to stand still and "be a tree" when the puppy gets mouthy rather than running and screaming, which triggers the puppy's chase instinct and makes biting worse.
Frequently Asked Questions
Is it normal for a 5-month-old puppy to still bite hard?
Yes, 5 months is still within the teething window since adult teeth are actively pushing through the gums. The biting should decrease significantly by 6-7 months once all 42 adult teeth are in place. If hard biting persists past 7 months, consult a certified dog trainer to address the behavior before it becomes a habit.
Should I use bitter apple spray to stop puppy biting?
Bitter apple spray works well on furniture and shoes, but it is not effective for teaching bite inhibition with human skin. The goal is not to make your hands taste bad but to teach the puppy that biting ends the fun. The "Ouch" method and redirection are far more effective long-term strategies.
Do some breeds bite more than others during teething?
Herding breeds like Border Collies and Australian Shepherds tend to be mouthier because they are genetically wired to nip at heels. Retrievers also have very oral tendencies since they were bred to carry things in their mouths. The biting itself is not worse, but these breeds may need more consistent redirection and a bigger supply of appropriate chew toys.
