Can dogs eat aubergine?

The detail

Aubergine belongs to the nightshade family, alongside tomatoes, potatoes and peppers. All of them contain solanine, a compound that can be harmful in large amounts, but in food-crop nightshades it is concentrated in the green parts and unripe fruit, not the ripe flesh most people cook with.

A few bites of plain, cooked aubergine carry only a trace amount of solanine and are unlikely to cause more than mild nausea in a healthy dog. The bigger everyday risk is overdoing the portion: aubergine is fibrous, and too much of it can bring on loose stools or vomiting the same way any unfamiliar vegetable might.

Cooking softens the skin and flesh, which makes it easier to digest than raw aubergine. Dogs with kidney disease, arthritis or a known sensitivity to nightshade vegetables are usually better off avoiding it, so check with your vet if any of those apply.

Aubergine has no meaningful nutritional case for a dog on a complete, balanced diet. It is worth offering for variety or as a low-calorie treat rather than for any specific health benefit, and it should stay a small extra alongside the dog's usual food rather than a replacement for any of it.

A typical UK supermarket aubergine weighs somewhere around 250 to 300g, most of it water and fibre rather than anything a dog needs. That size is useful context when you are deciding what counts as a small taste versus a portion worth worrying about.

Raw aubergine vs cooked aubergine

Raw aubergine is tougher, more fibrous and slightly higher in solanine than cooked, and it is more likely to cause stomach upset in a dog that eats more than a token bite. Cooking, whether steamed, boiled or baked without oil, softens the flesh and lowers the solanine content further.

Cooked and plain is the safer version to offer if you want to try it at all.

Grilling or roasting is fine as long as nothing is added to the pan. Butter, oil, salt and garlic are all easy to add without thinking about it if you are cooking a portion for yourself at the same time.

Aubergine skin: peel it or not?

The skin is edible and not toxic, but it is tougher and more fibrous than the flesh, which can make it harder for some dogs to digest, especially in a larger piece. Cooking until soft reduces this, so a well-cooked skin is less of an issue than a raw one.

For a dog with a sensitive stomach, peeling it first is the simpler option.

PetMD specifically recommends peeling for dogs that struggle with fibre, which is a reasonable default if you are trying aubergine with a dog for the first time and do not yet know how they will react.

Ratatouille, moussaka and other cooked aubergine dishes

The aubergine itself is not the problem in most cooked dishes; the garlic, onion, oil, salt and stock cubes usually mixed in with it are. A spoonful of ratatouille or moussaka is not the same food as plain cooked aubergine, and both of those common recipes typically contain garlic or onion, which are unsafe for dogs.

If your dog steals a portion of a cooked aubergine dish, check the recipe for garlic and onion rather than assuming the aubergine is the only ingredient that matters.

Curries built around aubergine carry the same issue, plus spices and sometimes chilli that a dog's stomach will not thank you for. None of these dishes are a way to feed aubergine safely, however small the aubergine content looks on paper.

Aubergine and nightshade sensitivity

A small number of dogs react to nightshade vegetables with itching, ear infections, gastrointestinal upset or excessive paw licking, separate from any solanine dose. This is a food sensitivity rather than poisoning, and it shows up with repeated exposure rather than a single meal.

If you notice a pattern after aubergine, tomato or potato specifically, mention it to your vet before continuing to feed any of them.

Introducing aubergine to a sensitive dog or a puppy

Start with a single small cube of cooked, plain aubergine and wait a day before offering more, the same way you would introduce any new vegetable. A dog with a history of a sensitive stomach is more likely to react to the fibre content than to solanine specifically.

If a first small taste causes no loose stools or vomiting, aubergine can join the rotation of occasional vegetable treats at the modest portions in the table above.

A puppy's digestive system is more easily upset by any new food, so the same one-small-piece-and-wait approach applies, and there is no nutritional reason to rush it. Waiting until a puppy is past the wobbliest stage of weaning and settled on solid food is a reasonable default.
