Plain, chopped celery is safe for most healthy dogs. It can even be a handy low-calorie snack or added as a topper to dog food. The slightly longer answer is that there's a right way to serve it, and a few situations where it might not be the best choice for your dog.
In this guide, we'll walk through the benefits, raw versus cooked celery, the leaves and juice, how to prepare it properly, sensible portion sizes, the choking risk that catches a lot of owners out, and the dogs who should give it a miss. We'll also clear up a myth you've probably read elsewhere about celery and clean teeth.
Is celery safe for dogs?
Yes. Plain, chopped celery is safe for most healthy dogs, and it sits on the PDSA list of fruit and veg that dogs can eat in small amounts. It's non-toxic, low in calories, and most dogs handle it perfectly well as an odd treat.
What are the benefits of celery for dogs?
Celery is roughly 95% water, which is part of what makes it so light. It's very low in calories and fat, and it offers some fiber along with small amounts of vitamin K, vitamin C, folate and potassium (British Nutrition Foundation).
If you’re keeping an eye on your dog’s waistline, celery can be a handy option. A few pieces make a satisfying, crunchy snack without piling on calories, so it works well as a lighter swap for richer treats. Its high water content can also offer a small hydration boost on warmer days, though fresh water should always be their main source. If you’d prefer something similarly light but made specifically for dogs, our natural dog treats are another easy option to keep on hand.
It's also worth being honest about what celery isn't. It's simply a pleasant, low-calorie extra for dogs who enjoy it, no better or worse than any other safe veg.
It’s also worth saying celery isn’t a miracle snack. It’s just a simple, low-calorie extra for dogs who enjoy it, about the same as any other dog-safe veg.
Now for the myth. You'll often read that celery cleans a dog's teeth or freshens their breath. It's a nice idea, but the evidence doesn't really back it up. There's no good proof that crunching on fibrous foods like celery removes plaque or tartar in any meaningful way (RCVS Knowledge). What actually helps your dog's teeth is regular brushing, which UK veterinary guidance still treats as the gold standard for dental care (PDSA). So enjoy celery for what it is, and keep the toothbrush for the dental job.
Can dogs eat raw celery?
Yes, and raw is how most dogs end up trying it, usually because a piece has been shared from the chopping board. Give the stalk a thorough wash under cold running water first to remove any soil or residue, trim off the tough base, and chop it into appropriately sized pieces for your dog.
Raw celery is crunchy and fibrous, which is exactly why the choking risk applies most here, especially for small breeds. Smaller pieces are always safer. Some dogs will adore the crunch and come back for more, while others will give it one sniff and walk off entirely. Both reactions are completely normal, and there's no need to coax a dog who isn't interested.
If you're reaching for celery as a cooling snack when the weather warms up, it isn't the only option. Watermelon for dogs is another safe, hydrating choice on a hot day.
Can dogs eat cooked celery?
Plain cooked celery is also safe, and it can be a little nicer for dogs with sensitive stomachs because cooking softens the fibre and makes it easier to digest. Boil, steam, or poach it with nothing added. So no oil, butter, salt, or seasoning.
What you do want to avoid is celery that's been cooked into a dish. Stews, soups, stocks, and stir fries almost always contain onion, garlic, or salt. And onion and garlic are toxic to dogs even in fairly small amounts (Blue Cross). A few plain steamed pieces are fine. A scoop of the casserole isn't.
Can dogs eat celery leaves and tops?
The leafy tops are safe in small amounts too. They actually carry a little more of some vitamins than the stalks do, but they're also more bitter, so don't be surprised if your dog turns their nose up. Wash them, chop them small, and treat them exactly as you would the stalks. Skip any leaves that have gone wilted or are turning brown.
Can dogs eat celery juice?
This one's best avoided. Juicing strips out most of the fibre and concentrates the natural sodium, and it's not something a dog needs in the first place. A few licks from a worktop spill are nothing to worry about, but celery juice shouldn't be served as a drink. Plain, fresh water is always the better choice for keeping your dog hydrated.
How to prepare celery for your dog
A little preparation makes celery much safer and more enjoyable. Here's the simple version:
-
Pick a fresh stalk, ideally one that snaps cleanly rather than bending
-
Wash it thoroughly under cold running water and trim off the tough base
-
Pat it dry and chop it into pieces sized for your dog: matchstick-thin for tiny breeds, half-coin slices for medium dogs, and slightly larger chunks only for big dogs who chew properly rather than gulp
-
Serve it plain on its own, add it as a topper to their main meal, or use small bits as light training rewards
Celery can also be a nice way to add a bit of crunch and variety to a bowl of complete dog food. Mixing things up like this is common: around 46% of dog owners already feed a combination of wet dog food and dry dog food, so adding the odd vegetable topper fits naturally into that habit. If you do end up with leftover wet food after topping a bowl, we’ve made a guide on how to store dog food leftovers to keep it fresh and safe.
How much celery can dogs eat?
Treats and toppers of any kind, celery included, should make up no more than around 10% of your dog's daily food intake (PDSA). The rest should come from their complete food
Every dog's different, and things like size and activity level all play a part, so treat the following as a loose guide rather than a strict measure:
-
Small dogs (under 10kg): a few matchstick-sized pieces, roughly a tablespoon
-
Medium dogs (10 to 25kg): around two tablespoons of chopped celery
-
Large dogs (over 25kg): up to a small handful of chopped celery, now and then
Choking risk and small dogs
This deserves its own moment, because it's the biggest practical risk with celery. The stringy fibres can wrap around the throat or get lodged if the pieces are too big, and small dogs and quick eaters are the most likely to run into trouble.
A few sensible habits go a long way. Always chop celery into bite-sized pieces, supervise the first few times your dog tries it, and never hand over a whole stalk for them to chew through. If your dog starts coughing, retching or panicking after eating celery, ring your vet for advice straight away. The Animal PoisonLine, run by the Veterinary Poisons Information Service, is also a useful 24-hour UK number to have to hand if you think other ingredients might have been involved (Animal PoisonLine, n.d.).
When celery might not suit your dog
For most dogs, celery's a harmless treat. There are a handful of situations, though, where it's worth pausing or running it past your vet first:
-
Dogs with heart conditions or on a low-sodium diet. Celery contains a small amount of natural sodium, which can add up if it's being eaten regularly alongside other treats. Dogs managing heart disease are often on carefully controlled sodium, so it's best discussed with your vet (VetCompass).
-
Dogs with diagnosed kidney disease or on a prescribed renal diet. The potassium content's worth flagging with your vet before celery becomes a regular feature.
-
Dogs with sensitive stomachs. High-fibre veg can cause loose stools or a bit of gas in some dogs. Start with a tiny amount and see how they get on. A gentle, limited-ingredient recipe like our Just 6 dog food can also help if your dog tends to react to changes in their food.
-
Puppies on their first solids. Small amounts of plain, finely chopped celery are fine once a puppy's fully weaned, but the bulk of their diet should always be a complete puppy food made for their stage of growth.
-
Dogs with confirmed food sensitivities. Most food sensitivities relate to proteins rather than vegetables, and true food allergies are uncommon in dogs (Mueller et al., 2016). Even so, if you're partway through an elimination diet with your vet, hold off on introducing any new foods until that's finished.
A quick chat with your vet can help put your mind at ease if you’re unsure.
