What you need before you start

  • Alcuni oggetti da masticare adatti alla taglia e all'età del cucciolo, di durezza diversa
  • La pazienza di reindirizzare il morso ogni volta, con costanza, invece di punire
  • Un ambiente già messo in sicurezza, con cavi e piccoli oggetti fuori portata

A puppy explores the world with its mouth, and during teething another need is added to that one: chewing eases the discomfort of the gums as the milk teeth give way to the adult ones. Mouthing hands, furniture and shoes is therefore not spite or a sign of aggression, but normal behaviour to be guided, not suppressed. The point is not to stop the puppy biting, which is impossible, but to teach it what it may bite and what it may not, offering good alternatives and removing the wrong opportunities. This guide explains why it happens, how to redirect the bite consistently, which chew objects to choose safely, and which signals during teething deserve a vet visit.

Understand why the puppy mouths

Before correcting a behaviour it helps to understand it, otherwise you fight the symptom and not the cause. Puppy mouthing comes from several needs that often overlap, and recognising which one prevails at a given moment changes the right response.

  • Exploration: the mouth is its way of getting to know objects and materials in the first months.
  • Teething: between roughly three and six months the milk teeth fall out and the gums are sore, and chewing eases it.
  • Play: biting is part of play between puppies, and needs redirecting when it lands on hands.
  • Overexcitement and tiredness: an overstimulated puppy or one that needs to sleep bites more, not less.
  • Attention seeking: if biting makes people react, the behaviour is reinforced even unintentionally.

Redirect the bite without punishing

  1. Always keep a chew object to hand

    When the puppy goes for a hand or a piece of furniture, the quickest and most effective thing is to put a legitimate chew object in front of it. Redirecting works only if the alternative is immediately available, not to be fetched from another room.

  2. End play when the bite lands on skin

    If during play the teeth touch skin, stop the game for a few moments while staying calm and neutral. The puppy learns that biting the hand ends the fun, while biting the toy keeps it going.

  3. Do not turn hands into a game

    Never use your hands as an object to chase and bite, not even in jest. A puppy does not tell the playing hand from the stroking one, and what is cute at two months becomes a problem at six.

  4. Reward the right choice

    When the puppy chooses on its own to bite its toy instead of the hand or the furniture, acknowledge it with a warm voice or a treat. Reinforcing the right behaviour is more effective than suppressing the wrong one.

  5. Handle overexcitement with a break

    If the puppy enters a frantic biting phase and will not stop, do not raise the level of play: offer it a moment of calm in a quiet spot. Often it just needs to release the tension by sleeping.

  6. Apply the same rule with everyone

    Everyone in the home must respond the same way. If one person allows hand biting, the puppy gets contradictory messages and learning slows or stalls.

Choose chew objects safely

Not everything sold as a chew is suitable, and some are too hard or break into dangerous pieces. The choice should fit the puppy's size, age and way of chewing, and the objects should be checked often and replaced when they give way.

How to assess a chew object
CriterionWhat to preferWhat to avoid
HardnessGives slightly under a nail, not too rigidObjects that do not deform at all, which risk breaking teeth
SizeLarge enough not to be swallowed wholeSmall objects or ones that reduce to swallowable pieces
IntegrityMaterial that wears down without shedding hard fragmentsToys that crumble or lose detachable parts
Gum reliefSome objects can be chilled to soothe the discomfortFrozen, rock hard objects, too aggressive on the teeth
SuitabilityDesigned for puppies, in keeping with size and ageHousehold objects, old shoes, sticks picked up outdoors

Teething and when the vet is needed

The loss of milk teeth and the arrival of the adult ones are normal processes that usually need no intervention. You may find a little tooth on the floor or a small trace of blood on a toy, and in most cases there is nothing to worry about. Some signals, though, deserve a check.

  • A milk tooth that does not fall out while the adult one has already come through beside it, which the vet should assess.
  • Very swollen, painful gums or ones that bleed persistently, beyond the occasional small trace.
  • Very bad breath, marked refusal of food or obvious difficulty chewing.
  • A broken or chipped tooth or a mouth injury after biting something too hard.
  • Adult teeth growing misaligned or that seem to injure the gums.

Frequently asked questions

Until what age does a puppy mouth because of teething?
The most intense teething related phase is generally between roughly three and six months, when the milk teeth fall out and the adult ones arrive, but the need to chew and playful mouthing can continue beyond that. With consistent redirection the behaviour eases as the puppy grows and learns self control. If biting stays intense well past this phase, it is worth reviewing management and stimulation, and possibly working with a trainer.
My puppy bites my hands when it plays: is that aggression?
Almost never. In a puppy, biting during play is normal behaviour it uses to explore and interact, not a sign of aggression. Your job is to teach self control by redirecting the bite onto objects and ending play when the teeth reach skin. If instead you notice stiffening, growling outside play, or bites that seem defensive, it is worth getting help from a behaviour professional.
Can I give ice cubes to soothe the gums?
Cold can bring relief, but an ice cube is very hard and some puppies chew it eagerly, risking damage to their teeth. Better to use chew objects designed to be chilled, which stay slightly yielding. Either way watch how it chews: if it is too aggressive on something too hard, take the object away. When in doubt about what is suitable, ask the vet.
What if it always chews the same furniture?
Act on two fronts together: remove the opportunity and offer the alternative. Make the furniture less accessible or less appealing and make sure there is always a legitimate chew object to hand, redirecting each time with patience. Also check the puppy is not bored or tired, because furniture chewing often increases when there is no suitable outlet or when it needs to rest.

What to do next

Treat mouthing as a normal need to guide, not spite to punish: always keep a legitimate chew object to hand, redirect consistently every time, and end play when the teeth reach skin. Never use your hands as a game and apply the same rule with everyone in the home. Choose chew objects suited to size and age, checking them often, and take to the vet any milk teeth that do not fall out, gums that bleed for a long time, broken teeth or marked difficulty chewing.
