Can dogs have gravy?
Updated 5 August 2026
No. Almost all UK gravy is made with onion powder and a lot of salt, and onion in any form damages a dog's red blood cells. A lick from a dropped plate is not an emergency, but gravy poured over dog food is a habit worth breaking. Plain unsalted meat juices are the safe swap.
If your dog has eaten gravy
A lick off the floor needs fresh water and nothing else. For anything more, a gravy boat, a jug or gravy over a stolen dinner, ring your vet with your dog's weight and an estimate of the amount, even if your dog seems fine, because onion damage can take days to show.

The detail
This question usually comes from a kind impulse: a Sunday roast, a begging face, and the old habit of tipping leftover gravy over the dog's dinner. The problem is what UK gravy is actually made of.
Commercial gravy is built on salt and onion powder. Onion is toxic to dogs whether fresh, cooked, dried or powdered, and the damage it does to red blood cells often shows up days after the meal rather than on the day.
The salt stacks on top. Bisto Original works out at about 1.7g of salt per 100ml once made up, so a 150ml pour over a bowl of food carries around 2.5g of salt a dog has no use for.
Homemade gravy dodges the granules but rarely the risk. Most recipes start with an onion in the roasting tin, and even onion-free versions lean on stock cubes, butter and meat fat. The safe version of this idea is plain unsalted meat juices with the fat skimmed off.
Risk by gravy type
| Granules (Bisto and own brands) | Onion powder plus up to 1.7g of salt per 100ml made up |
| Stock cube gravy (Oxo) | About 1g of salt per cube, plus onion powder |
| Onion gravy | The worst option. Treat any real amount as onion ingestion |
| Plain unsalted meat juices, fat skimmed | Safe. The only version worth sharing |
Can dogs have Bisto gravy?
Bisto is the gravy most UK dogs actually meet, so it deserves a straight answer: no. The granules list onion powder among the ingredients, and the Original variety carries about 1.7g of salt per 100ml once made up.
The reduced salt version fixes the smaller of the two problems. The onion powder is still in there, so it stays off the dog's dinner just the same.
Can dogs have Oxo cube gravy?
An Oxo beef cube packs about 1g of salt into 6g of cube, alongside onion powder dried to stock-cube concentration. Gravy made from one is salty onion water as far as your dog's body is concerned.
A splash licked off the floor is not a poisoning. Making it a mealtime topper is where the harm builds, because the onion dose repeats every day.
Is homemade gravy safe for dogs?
Usually not, because most homemade gravy starts with an onion. Deglazing a roasting tin the onions cooked in carries their compounds straight into the liquid, so leaving the chunks out does not make it safe.
An onion-free version made with stock cubes, wine or butter still fails on salt and fat. Fatty scraps and drippings are a known trigger for pancreatitis in dogs, which is a painful condition rather than a passing upset.
Gravy on dog food: the honest answer
Plenty of owners tip gravy over kibble to get a fussy dog eating, and it works because dogs love the smell of meat fat. The habit is the danger: a daily dose of onion powder is exactly the repeated exposure that builds red blood cell damage over time.
The swap that keeps the ritual is plain meat juices. Pour off the resting juices before you season anything, skim the fat, and freeze them in an ice cube tray so one cube melts over dinner.
Warm water does more than you would expect too. It releases the smell of the food, which is most of what the gravy was doing anyway.
My dog licked some gravy. What now?
A lick or a splash from a dropped plate is a trace amount, and a healthy dog will walk it off. Put water down and carry on.
A drained gravy boat or a stolen plateful is different. Ring your vet with your dog's weight and a guess at the amount, even if nothing seems wrong, because onion signs can take days to appear.
Signs to watch for
- Vomiting or diarrhoea in the first 24 hours
- Lethargy, pale gums or fast breathing, sometimes days later
- Dark or reddish urine
- Excessive thirst after a salty serving
Common questions
My dog licked gravy off my plate. Should I worry?
No. A lick is a trace exposure, well below the amounts that cause trouble. Put water down and keep the gravy boat out of reach.
Can I put gravy on my dog's food to help them eat?
Not commercial gravy, because the onion powder dose repeats with every meal. Plain unsalted meat juices or warm water over the food does the same job safely.
Is reduced-salt or onion-free gravy okay for dogs?
Reduced-salt Bisto still contains onion powder, so no. A truly onion-free, unsalted gravy is really just meat juices, and that version is fine.
What about gravy made for dogs?
Pet shop gravy toppers are a different product, made without onion and with far less salt. Check the label reads as meat and stock with nothing from the allium family, and follow the feeding guide.
How much gravy would actually harm my dog?
There is no clean threshold, because the onion concentration varies by brand and recipe. VCA Animal Hospitals puts consistent onion toxicity above 0.5 percent of body weight eaten at once, so let your vet do that maths with the real amounts.
How quickly would poisoning show?
Stomach upset can start within hours, but the anaemia from onion damage often takes one to five days. Seeming fine the same evening does not rule it out.
