You hand your dog a lovely new chew, and instead of tucking in, they trot off to hide it behind the sofa cushion or bury it in the flowerbed, complete with a careful little nose-tamp of imaginary soil over the top. It looks comical, but it is one of the oldest and most natural behaviours a dog has. So why does your dog bury things? In short, it is a deeply wired survival instinct: the urge to save valuable resources, especially food, for later. It is almost always completely normal and nothing to worry about.
Wild ancestors of the dog could not rely on a full bowl twice a day. When they had more food than they could eat, hiding the surplus, out of sight of rivals and scavengers, meant a meal in leaner times. This is known as caching, and it is common right across the animal kingdom, from squirrels and foxes to many bird species. Wikipedia has a clear overview of food hoarding and caching in animals if you fancy the science.
It is a food-caching instinct
Even though your dog knows dinner is coming, the ancient "save it for later" programme still fires. When they are given more than they need, or something too precious to eat all at once, the instinct kicks in to stash it somewhere safe. Bones, chews, high-value treats and even a favourite toy are the usual candidates. Your carpet, garden and plant pots simply stand in for the forest floor.
Common things dogs bury, and where
- Bones and long-lasting chews: the classic buried treasure.
- Toys: especially new or favourite ones they want to keep safe.
- Food they cannot finish: surplus from a generous meal or treat.
- Odd household objects: the TV remote, socks or your slippers occasionally get the treatment too.
Indoors, dogs "bury" by pushing items under cushions, into laundry baskets, behind furniture or down the side of the bed, then nosing at the surrounding surface as if covering them. Outdoors, they dig properly and pat the soil down.
Which dogs bury the most
Any dog can bury, but some are keener than others:
- Breeds bred to dig, such as terriers and dachshunds, often love it.
- Dogs given lots of high-value chews and bones have more to cache.
- Free-fed or food-motivated dogs may stash surplus rather than eat it all.
Worth knowing: Burying is a normal, self-rewarding behaviour, so trying to stamp it out completely is usually a losing battle and can frustrate your dog. It is far kinder to redirect it than to punish it.
When burying might signal something more
Burying itself is healthy, but the context around it occasionally tells a different story:
- Sudden, frantic or obsessive hiding of food can appear in a dog who feels anxious or insecure about resources, sometimes in multi-dog homes.
- A hungry dog burying food they would normally eat could point to nausea, dental pain or an upset tummy that puts them off eating now.
- Compulsive, repetitive digging or hiding that is hard to interrupt, or that comes with other stress signs, is worth a closer look.
Vet note: If your normally keen eater starts hiding food instead of eating it, or the digging becomes frantic and obsessive, it is worth ruling out dental pain, nausea or anxiety with your vet. For behaviour that seems driven by stress rather than simple instinct, a qualified behaviourist through the APBC or ABTC can help. The RSPCA also has sensible guidance on understanding dog behaviour.
How to manage burying kindly
You do not need to stop it, just channel it:
- Feed appropriate portions so there is less surplus to cache.
- Offer chews at sensible times and pick up what is not finished after a while, so there is nothing to hoard.
- Give a digging outlet. A sandpit or a designated digging patch in the garden lets outdoor buriers dig to their heart's content, away from your borders.
- Do not tell them off. Punishing an instinct only causes confusion and stress. Redirect instead.
If your dog buries a chew and later drags out a mucky, gritty one, a quick freshen-up groom sorts out any dirt or garden debris caught in the coat.
Frequently asked questions
Why does my dog bury bones and toys?
It is the caching instinct: an ancient urge to store valuable food and possessions for later. Hiding treasures where rivals cannot find them was a survival advantage for wild ancestors, and the instinct lingers today.
Why does my dog pretend to bury food indoors?
With no soil to hand, dogs improvise by pushing items under cushions or behind furniture and "covering" them with nose movements. It is the same instinct playing out on carpet instead of earth.
Is it bad that my dog buries food?
Usually not, it is normal. Only worry if a hungry dog suddenly hides food they would normally eat, or the behaviour becomes frantic and obsessive, in which case a vet check is wise.
How do I stop my dog digging up the garden to bury things?
Reduce surplus food and chews, and give a legitimate outlet such as a sandpit or a set digging area. Redirecting the instinct works far better than punishment.
