Puppy Mouthing and Play Biting: How to Stop It

Those razor-sharp teeth aren't weapons. They're learning tools.

🐶Why Puppies Mouth and Bite

• ●Exploring the world (like toddlers touch everything)
• ●Learning bite pressure (what hurts, what doesn't)
• ●Playing (this is how puppies play with each other)
• ●Teething discomfort (chewing helps soothe gums)
• ●Overstimulation or overtiredness

📖This Is Normal

Every puppy bites. It's not a sign of aggression, dominance, or a "bad" puppy. It's developmentally necessary.

👄The Goal Isn't to Stop All Mouthing

It's to teach "bite inhibition" - controlling jaw pressure. A dog that never learned this can cause serious damage if they ever bite in fear or pain.

📖The Dangerous Misunderstanding

Some people punish puppy biting harshly. This suppresses the behaviour but doesn't teach control. Those dogs may give a full-force bite as adults because they never learned to moderate pressure.

This is the most important thing your puppy learns from biting.

🐶What Puppies Learn from Littermates

When puppies play-bite siblings, they get feedback: - Bite too hard → sibling yelps and stops playing - Lesson learned: hard bites end fun

This happens hundreds of times before you get your puppy. But it continues with you.

📖The Stages

1. First: Stop the hard bites (the ones that break skin) 2. Then: Reduce pressure of remaining bites 3. Then: Reduce frequency of mouthing 4. Finally: Redirect to toys

📖Don't Skip to the End

If you immediately suppress all mouthing without teaching pressure control, you skip the crucial lesson.

📖Timeline

• ●8-12 weeks: Lots of biting, working on pressure
• ●12-16 weeks: Less intense biting, redirecting to toys
• ●4-6 months: Occasional mouthing, should be gentle
• ●6+ months: Should be rare, very controlled

First, address the painful bites.

🐶When Puppy Bites Hard

1. Make a high-pitched "OW!" or yelp 2. Turn away, end interaction for 3-5 seconds 3. Resume play 4. Repeat as needed

Does the Yelp Work? For many puppies, yes. But some puppies get MORE excited by yelping. If yours does:

• ●Skip the yelp
• ●Simply freeze, turn away, disengage
• ●Leave the room if needed

📖The Leaving Method

1. Puppy bites hard 2. Stand up calmly, step over baby gate, leave room 3. Wait 10-30 seconds 4. Return and resume 5. Repeat

📖Consistency is Critical

Every person in household must respond the same way to hard bites.

🐶Puppies Learn

Hard bites = fun ends. They start moderating pressure.

Once bites are softer, work on reducing frequency.

📖Redirect to Toys

• ●Always have a toy handy
• ●When puppy goes for hands, offer toy instead
• ●Make the toy exciting (wiggle, drag, toss)
• ●Praise when they take the toy

🐶Good Toys for Mouthy Puppies

• ●Rope toys (great for tugging)
• ●Soft squeaky toys
• ●Stuffed Kongs
• ●Rubber chew toys
• ●Anything they can sink teeth into

📖Teach "Leave It"

1. Hold treat in closed fist 2. Puppy will lick, paw, mouth 3. The moment they back off, "Yes!" and give treat 4. Build up to open hand 5. Use on hands: when they mouth, "leave it" then redirect to toy

📖The "Oops, Wrong Choice" Method

• ●Hands approach puppy for nice petting
• ●Puppy bites → hands withdraw → no attention
• ●Puppy doesn't bite → petting and praise continue
• ●Teaches: gentle mouth = good things happen

Most biting spikes happen when puppies are wound up.

📖The "Witching Hours"

Most puppies have crazy times (often evening). Biting increases when: - Overtired (puppies need 18-20 hours sleep) - Overstimulated - Hasn't been to toilet recently - Hungry

📖Enforced Naps

• ●Puppies don't always know they're tired
• ●If going crazy: crate for a nap
• ●Not punishment - meeting a need
• ●Wake calmer, bite less

😌Calm Play

• ●Avoid games that rev up (rough wrestling)
• ●Tug is fine IF rules are followed
• ●Reward calm behaviour heavily

📖When to End Play

• ●Before puppy gets too wild
• ●Quit while you're ahead
• ●If biting escalates despite redirection → nap time

Tired puppies bite less. Here's how to wear them out safely.

💪Physical Exercise

• ●Multiple short play sessions (not one long one)
• ●Avoid over-exercising (joints are developing)
• ●Rule of thumb: 5 mins per month of age, twice daily
• ●Swimming and controlled play are gentle on joints

💪Mental Exercise

• ●Puzzle feeders
• ●Snuffle mats
• ●Training sessions
• ●Scatter feeding in grass
• ●Lick mats with frozen food

🦴Chewing

Appropriate chewing = less inappropriate mouthing - Frozen Kongs (stuff with food, freeze overnight) - Safe chews (avoid cooked bones, rawhide from unknown sources) - Rotate chew toys to keep interesting

📖Sniffing

Sniffing is mentally tiring. Let puppy sniff on walks.

Teething puppies bite more. Prepare for it.

📖When It Happens

• ●Baby teeth fall out from about 3-4 months
• ●Adult teeth come in between 4-7 months
• ●Molars cause most discomfort

📖Signs of Teething

• ●Increased chewing on everything
• ●Blood spots on toys
• ●Finding tiny teeth
• ●Increased biting/mouthing

📖How to Help

• ●Frozen washcloths to chew
• ●Frozen Kongs
• ●Ice cubes
• ●Rubber teething toys (Nylabone puppy)
• ●Carrot sticks from freezer

📖During This Time

• ●Expect some regression in bite inhibition
• ●Be patient but consistent
• ●Provide lots of appropriate outlets
• ●This too shall pass

Some common advice makes things worse.

📖Don't

📖Hold their mouth shut

• ●Scary and doesn't teach anything
• ●They'll bite harder when released
• ●Damages trust

📖Alpha roll / scruff shake

• ●Dominance theory is outdated nonsense
• ●Creates fear and defensiveness
• ●Can make biting worse

📖Spray water / citronella

• ●Punishes but doesn't teach
• ●Creates anxiety around hands
• ●Damages relationship

📖Flick or tap their nose

• ●See above
• ●Also, puppies think fast hands = play

📖Yell or intimidate

• ●Fear is not a training tool
• ●May suppress biting temporarily but causes fallout
• ●Puppy learns to fear you, not to control their mouth

📖These methods often "work" initially but

• ●Create fear-related behaviours
• ●Puppy becomes hand-shy
• ●May redirect to other family members
• ●Can create an adult dog that bites without warning (because warning was punished out)

Most puppy biting is normal. But some isn't.

🦷Normal Puppy Biting

• ●During play
• ●When overstimulated
• ●Releases when redirected (eventually)
• ●No other aggression signs
• ●Responding to training over time

📖Concerning Signs

• ●Stiff body, hard stare before biting
• ●Growling with hackles up
• ●Snapping at face/neck with intent
• ●Resource guarding (biting when near food/toys)
• ●Biting without any apparent trigger
• ●No improvement despite consistent training

📖If You See These

Contact a qualified behaviourist (APBC or ABTC registered in UK). Not a trainer - a behaviourist.

🛡️Resource Guarding in Puppies

This is manageable but needs professional guidance. Don't try to "train it out" by taking things away. You'll make it worse.

Everyone needs to be consistent.

👶Children and Puppies

• ●Supervise ALL interactions
• ●Teach children to "be a tree" when puppy bites (stand still, arms folded)
• ●Running and squealing excites puppies
• ●Children should not play tug unsupervised
• ●Separate when overwhelmed

👶Teaching Children

• ●Show them how to redirect to toys
• ●Explain why we don't yell at puppy
• ●Have them practice calm interactions
• ●Praise gentle play

🐕Visitors

• ●Warn them puppy is mouthy
• ●Provide toy to redirect
• ●Can use lead to prevent jumping/biting
• ●Remove puppy if too excited

👨‍👩‍👧Elderly or Frail Family Members

• ●Careful supervision
• ●May need to keep puppy contained during visits
• ●Puppy teeth can break thin skin
• ●Safety first

When will this end? Here's what's realistic.

📖8-12 Weeks

• ●Lots of biting
• ●Focus on pressure, not frequency
• ●Many daily redirections

📖12-16 Weeks

• ●Pressure should be reducing
• ●Mouthing still frequent
• ●Redirecting to toys should work faster

📖4-6 Months

• ●Teething regression (more chewing)
• ●Much less biting at hands
• ●Should take a toy readily

📖6-9 Months

• ●Occasional mouthing
• ●Should be very gentle
• ●Adolescent "forgetting" may occur

📖12+ Months

• ●Rare mouthing
• ●Very soft mouth
• ●Takes toy instead automatically

📖Remember

Progress isn't linear. There will be bad days. What matters is the overall trend.

Every puppy is different. Some breeds are mouthier (retrievers, spaniels). Some individual puppies just take longer. Consistency and patience always win in the end.
