Why Feed Your Dog Fruits and Vegetables?
Dogs are omnivores, and while their diet should be primarily protein-based, many fruits and vegetables provide genuine nutritional benefits. They're packed with vitamins, minerals, antioxidants, and fibre that can complement your dog's regular meals.
Fresh produce also makes an excellent low-calorie treat alternative — especially useful for dogs watching their weight. But not all fruits and vegetables are safe, and even the safe ones need to be served correctly.
Here's your definitive guide to what's safe, what's toxic, and how to serve it all.
Safe Fruits for Dogs
Blueberries
Serving size: 5-10 berries for small dogs, up to 20 for large dogs
Blueberries are a superfood for dogs, loaded with antioxidants, vitamins C and K, and fibre. Their small size makes them perfect training treats straight from the punnet. They can be served fresh or frozen — many dogs love them as a cool summer snack.
Watermelon
Serving size: 2-3 small cubes for small dogs, up to a cup for large dogs
Watermelon is 92% water, making it a fantastic hydrating treat on hot days. It provides vitamins A, B6, and C. Always remove seeds and rind — seeds can cause intestinal blockages, and the rind is difficult to digest.
Apples
Serving size: 1-2 slices for small dogs, 3-4 slices for large dogs
Apples are crunchy, sweet, and full of fibre and vitamin C. They can also help freshen breath. Remove the core and seeds — apple seeds contain small amounts of cyanide, which is harmful in quantity.
Bananas
Serving size: 2-3 thin slices for small dogs, half a banana for large dogs
Bananas provide potassium, vitamin B6, and biotin. They're high in natural sugar though, so keep portions small. Frozen banana slices make a great occasional treat.
Strawberries
Serving size: 1-2 berries for small dogs, 3-4 for large dogs
Strawberries contain fibre, vitamin C, and an enzyme that can help whiten teeth. Cut them into bite-sized pieces to prevent choking. Like bananas, they're high in sugar, so moderation is key.
Pears
Serving size: 1-2 small cubes for small dogs, 3-4 for large dogs
Pears are a good source of copper, vitamins C and K, and fibre. Remove the pit and seeds before serving, as they contain traces of cyanide.
Cantaloupe (Rockmelon)
Serving size: 1-2 small cubes for small dogs, a few cubes for large dogs
Cantaloupe is hydrating, low in calories, and rich in beta-carotene. Remove the rind and seeds. It's on the sweeter side, so treat it as an occasional snack.
Cranberries
Serving size: A small handful
Fresh or frozen cranberries are safe and may support urinary tract health. Many dogs find them tart, though. Avoid dried cranberries with added sugar.
Safe Vegetables for Dogs
Carrots
Serving size: 1-2 baby carrots for small dogs, a full carrot for large dogs
Carrots are one of the most universally loved dog-safe vegetables. They're crunchy, naturally sweet, low in calories, and great for dental health. Serve raw for crunch or cooked for easier digestion. Rich in beta-carotene and fibre.
Green Beans
Serving size: A small handful (raw or steamed)
Green beans are a vet favourite for dogs on a diet — they're incredibly low in calories but filling. They provide vitamins C and K, manganese, and fibre. Serve plain with no salt, butter, or seasoning.
Sweet Potatoes
Serving size: 1-2 tablespoons of cooked sweet potato
Sweet potatoes are nutritional powerhouses with beta-carotene, fibre, vitamins A and C, and potassium. Always cook them — raw sweet potato is difficult for dogs to digest. Baked, boiled, or dehydrated into chews are all great options.
Pumpkin
Serving size: 1-2 teaspoons for small dogs, 1-2 tablespoons for large dogs
Plain cooked pumpkin (not pumpkin pie filling) is excellent for digestive health. It can help with both constipation and diarrhoea thanks to its soluble fibre content. It's also a staple recommendation from vets for settling upset stomachs.
Cucumber
Serving size: 2-3 slices for small dogs, half a cucumber for large dogs
Cucumbers are almost calorie-free and very hydrating. They're perfect for overweight dogs who still want plenty of treats. Serve sliced — no preparation needed beyond a wash.
Broccoli
Serving size: 1-2 small florets
Broccoli is safe in small amounts and provides vitamin C, fibre, and potassium. However, broccoli florets contain isothiocyanates, which can cause mild gastric irritation if consumed in large quantities. Keep it under 10% of daily food intake.
Celery
Serving size: 1-2 small sticks, chopped
Celery is low-calorie, hydrating, and contains vitamins A, C, and K. It can also help freshen doggy breath. Chop it into small pieces to prevent choking, especially for smaller dogs.
Peas
Serving size: A small handful of fresh or frozen peas
Green peas, sugar snap peas, and snow peas are all safe. They're rich in vitamins A, B, and K, plus protein and fibre. Avoid canned peas with added sodium.
Toxic Fruits and Vegetables — Never Feed These
Grapes and Raisins
Even small amounts can cause acute kidney failure in dogs. The toxic substance hasn't been definitively identified, and sensitivity varies unpredictably between dogs. There is no safe amount — avoid completely.
Onions, Garlic, Leeks, and Chives
All members of the allium family contain compounds that damage red blood cells, leading to anaemia. This applies to raw, cooked, powdered, and dehydrated forms. Garlic is sometimes marketed as a dog supplement, but veterinary consensus is that the risks outweigh any potential benefits.
Avocado
The flesh contains persin, which can cause vomiting and diarrhoea in dogs. The pit is also a choking and obstruction hazard.
Cherries
Cherry pits, stems, and leaves contain cyanide. While the flesh itself is technically safe, the risk of accidentally ingesting a pit makes them not worth the trouble.
Mushrooms (Wild)
While store-bought mushrooms are generally safe, wild mushrooms can be extremely toxic. Since it's difficult to identify safe species, it's best to avoid feeding any mushrooms to dogs.
Rhubarb
Rhubarb leaves contain oxalic acid, which can cause kidney problems. The stalks are also not recommended.
