Chewing, Biting and Digging in Dogs

Chewing, mouthing, puppy biting and digging are normal dog behaviours that land in inconvenient places. They usually come from a real need, like teething, play, boredom, heat or big excitement with nowhere to go. The approach that tends to help is the same across all four. Block access so the wrong choice cannot be practised, give the urge a legal outlet that genuinely satisfies it, and reward the behaviour you want instead.

Which part of chewing and destruction is it?

Somewhere else to start

Why these four problems belong in one group

Teeth and paws are how dogs interact with the world. A puppy mouths your hand for the same reason it mouths a table leg, because that is how it explores and plays. A dog digs because the ground is cool, or something smells interesting under it, or because digging is simply a great activity when nothing else is happening. None of this is your dog being naughty. It is normal behaviour showing up somewhere that costs you a shoe, a skirting board or a flower bed.

Your dog also does not share your labels. A chair leg and a rubber chew are both just chewable objects, and one of them is right there. The flower bed and the sandbox are both diggable, and the flower bed has better smells. So instead of trying to switch the urge off, you make the right option the easy, obvious, well paid one, and you make the wrong option hard to reach while the new habit is still fragile.

One more thing ties these problems together. Every repetition makes the habit stronger. A dog that has chewed the sofa arm three times is more likely to chew it a fourth. A dog left alone in the yard to dig is rehearsing digging. That is why management is not cheating. It buys you the quiet weeks you need for the training to take hold.

  1. Watch for three daysWrite down when the chewing, biting or digging happens, who is there, and what was going on just before. Most dogs have two or three predictable trigger situations. You cannot fix a fog, but you can fix a pattern.
  2. Close the buffetDo a sweep at dog height. Shoes away, remotes up, laundry lidded, cords covered. Use gates or a pen for rooms you cannot supervise, and block the favourite dig spots with stones or planters for now.
  3. Offer a real outletGive the urge somewhere legal to go. That means a rotating menu of chews with different textures, a dig pit of loose soil or sand, and structured toy play where the toy stays between your hands and those teeth.
  4. Pay the behaviour you wantReward the thing that cannot happen at the same time as the problem. Feet on the floor at greetings, a mouth full of toy during play, a settle on the mat with a chew during the evening spike.
  5. Trade, never chaseIf your dog grabs something forbidden, chasing turns it into the best game in the house. Scatter a few treats a step away and pick the item up while your dog eats, or swap in something better.
  6. Give freedom back slowlyOpen up one room, or one solo yard session, at a time. If something gets chewed or a fresh hole appears, that is information, not failure. Shrink back a step for a week and try again.

Sleep, boredom and excitement sit underneath all of it

A lot of what looks like a training problem is really an unmet need. Puppies need a huge amount of sleep, roughly sixteen to twenty hours a day, and many are not getting close to that. The frantic evening biting that owners call demon mode is very often an overtired puppy, not a defiant one. A nap before the usual witching hour fixes what training cannot.

Boredom does the same job in older dogs. A dog left in the yard alone as a form of babysitting will find something to do, and digging is excellent entertainment. A dog with an empty afternoon will go shopping in your living room. Sniffing walks, food puzzles, scatter feeding and a daily chew session are not extras. They are the reason the rest of the plan sticks.

Excitement is the third piece. Mouthing that spikes at homecomings or in the evening is energy looking for an exit. Give it a scheduled one, like a short tug game with clear rules, and the random ambushes usually shrink.

Which problem fits your dog

Puppy biting and nipping is the version you get with a young dog and a mouth full of new teeth. Puppies bite their littermates too, and when they bite too hard the game stops. You can copy that lesson at home. Teeth on a toy keeps the fun going, teeth on skin makes you go still and boring for a few seconds. Do not yelp or jerk away, because fast movement makes you a better toy. Long, soft toys and something frozen for sore gums do a lot of the work.

Mouthing hands during play is the adolescent and adult version, and it is usually doing a job. It gets attention, it starts a game, or it lets off steam. Pushing your dog away still counts as attention and often reads as wrestling. The fix is changing what pays, and it only works if every person in the house plays by the same rules. The family member who secretly enjoys hand wrestling is the single most common reason this one stalls.

Chewing furniture or shoes needs both ends handled at once, management so the wrong items are out of reach and a chew menu good enough to compete. Variety matters more than expense, so think rubbery, edible, shreddable under supervision, and something cold if teeth are coming through. Read why dogs chew furniture and shoes and what helps for the full approach, including how to trade instead of chase.

Digging up the garden is the outdoor cousin. Fence line holes usually mean critters or interest in what is outside. Shady holes on warm days are climate control. Random holes when your dog is out alone are boredom. Work out the reason first, fix what you can, then hand over one legal dig zone that pays better than the flower bed.

When to pause and get more help

Some things in this group are worth a vet conversation before you train. If your dog repeatedly eats non food items like rocks, fabric or sticks rather than just chewing them, talk to your vet, because that deserves a medical look before it becomes an emergency. The same goes for a sudden change in behaviour, like frantic digging that appears out of nowhere alongside other new habits.

Watch the character of the mouthing too. Playful mouthing comes with a loose, wiggly body and softens quickly. If your dog stiffens, freezes or growls, if the mouthing has suddenly got harder, or if it happens when you touch a particular spot, treat that as information rather than disobedience. Stop the situation that triggers it and book a vet check to rule out pain.

Guarding is another one to take seriously. If your dog goes stiff or growls when you approach a chew, do not take it away to prove a point, and do not punish the growl, because the growl is your warning system. Give chews in a quiet spot and let your dog finish in peace. If it continues, or if children are involved, work with a qualified professional in person. Chewing that only happens when nobody is home may also be separation distress rather than boredom, and chews alone will not solve that.

Questions owners ask

Is chewing and digging normal, or is something wrong with my dog?

Both are normal. Chewing is a need rather than a behaviour problem, and it is strongest in puppies, teething adolescents, and bored or stressed dogs of any age. Digging is wired into many breeds and serves real purposes, like making a cool bed on a hot day, following an interesting smell, or burying something valuable. The problem is not the urge, it is the location. That is why trying to stamp it out usually fails, and why giving the urge an approved outlet tends to work better than trying to switch it off.

When should I involve a vet in a chewing or biting problem?

Speak to your vet if your dog swallows non food items like rocks, fabric or sticks rather than simply chewing them, since persistent non food eating deserves a medical look. Also book a check if mouthing suddenly changes character, becoming harder or stiffer, or if it happens when you touch a certain part of the body, because pain can look like behaviour. Sudden frantic digging alongside other new behaviours is worth mentioning too. Big behaviour shifts sometimes have a physical cause underneath them.

Will my puppy grow out of biting on its own?

Puppy biting does fade as teething ends and as your puppy learns to control its jaws, but what you do while it lasts shapes what comes next. Puppies learn softness because play pauses when they bite too hard, and you can copy that at home. If hands stay part of the game, some dogs simply carry hand mouthing into adolescence in a much bigger body. Dogs are individuals, so timelines vary, but teaching toy play and protecting sleep usually helps more than waiting it out.

Does more exercise stop destructive chewing and digging?

Exercise helps, but on its own it rarely settles these behaviours. A tired body with a bored brain will still go looking for a project. What tends to work better is a mix, so sniffing walks, food puzzles, scatter feeding and a daily chew session at the time of day your dog usually gets restless. For digging, that also means not using the yard as a dog sitter, since solo yard time is exactly when old habits get rehearsed and turn into strong routines.

My dog only chews when I am out, is that the same problem?

It might not be. Set up a phone camera and watch a short absence before you decide. A dog that wanders around, then settles down to chew, generally looks bored, and a sniffy walk before you leave plus a frozen chew project and a smaller dog proofed space often helps. Pacing, whining, scratching at doors, or chewing focused on exits looks more like distress about being left alone, and chew toys will not resolve that. That situation needs a different approach built around absences.
