Why do puppies bite and chew? Top tips to help!


Puppies are one big bundle of fun and energy with their happy smiles and wagging tails.

But when a wagging tail is accompanied by 40 kilos of leaping, bounding energy that doesn’t know when to stop, it can soon become less fun and much more of a problem.

Unfortunately, as owners of puppies, we tend to reinforce the behaviour that we think is “fun” by playing and encouraging them to do it when they are young, allowing our

This includes rough play, allowing them to nibble and bite at our hair and hands and jump up on us as they please. Whilst it might be okay when they weigh just a few kilos, when they grow up to weigh more and have a full set of teeth and a powerful jaws, we no longer want them to do this and so we start to tell them off or even punish them for the unwanted behaviour.

This is very confronting and confusing for your dog as you may have actually ‘taught’ them this behaviour and rewarded them for it, by allowing it to happen and continue when they were a puppy. Then suddenly they are being punished for something that they thought was perfectly acceptable behaviour.

This is what we refer to in training as setting your dog up to fail and is why it is so important to address any potential future behaviour problems as soon as they begin.

Biting and mouthing is one of the most common complaints of new puppy owners and is the issue we will focus on here.

Why does my puppy bite and mouth me?

Puppies explore their environment with their mouths and also use their mouths in play and when teething, so it is important that we allow them to do this, but direct in the right way.

One way that puppies learn to inhibit their biting is by playing with other puppies. When one puppy bites the other puppy too hard, the play stops. This is no longer fun for either puppy so they learn instinctively that if they want the play to continue, they must control their bite. We can teach our puppies the same thing.

Ways to divert your puppy mouthing and biting

You can encourage your puppy to chew on safe, durable and appropriate sized toys that can’t be swallowed.

Interactive treat dispensing toys like Aussie Dog or KONG toys are great for keeping their interest as well. Rotate two to three toys daily.

Fresh raw bones are good to exercise their jaw and clean teeth. Check with your Vet about what size and type is best for your puppy.

Do not encourage it!

Never allow your puppy to bite, chew or mouth you, even if it seems to be in play, as this reinforces the behaviour.

Definitely do not encourage rough play and biting. Often kids will get down on the ground with the puppy and roll around letting them jump all over them and bite their hair etc. which encourages the puppy to do it more and sets them up to fail.

Encourage interactive play using a ball, frisbee or tug toy instead.

If your puppy does bite walk away or fold your arms and ignore it. We do not want to give in to their attention seeking behaviour so no eye contact or verbal responses either.

Do not punish them!!!  Your puppy is still learning about the world through chewing and biting, so it’s important to instead just ignore them and remove access.

If your puppy goes to mouth or bite you could also gently offer a toy to redirect it. You do need to be very careful with timing so that the toy connects with their mouth before they have connected with your hand or body, otherwise it could be seen as a reward for the biting behaviour if they have managed to make contact with you and then receive the toy.

Try not to overexcite your puppy by waving your hands around and if they are biting it is also best not to use your hands to correct the behaviour. Slapping your puppy can make things worse. It can make some puppies hand shy or for others it might actually encourage aggression and more biting.

If they are chewing on plants or furniture you can make up a spray of chilli or vinegar in water to spray onto the plants or areas they chew, or there are a number of ‘chew stopper’ sprays available in shops.

Always put away items that they tend to chew like shoes, socks, kids toys etc.

Digging is also a common puppy behaviour, so sandpits are great to redirect digging and can help with boredom too when dogs are left alone at home. You can hide treats or toys in the sandpit to help direct any digging to this area.

Remember, dogs don’t grow out of problem behaviour, they grow into it, so we need to make sure we set a puppy up for life by teaching it the behaviour we will expect of it as an adult.

Puppy school is a great way to start. Or if you’re having a few issues, get the help of a qualified trainer before the problem gets too bad.
