Yes — dogs can eat bell peppers, and they’re one of the better vegetables you can share with your dog. Bell peppers are non-toxic, low in calories, high in vitamins and antioxidants, and genuinely enjoyable for most dogs who like a crunchy treat. Dr. Carly Fox DVM, Senior Veterinarian at the Schwarzman Animal Medical Center in New York City, confirms that bell peppers are not toxic and are a healthy alternative snack to share with your dog.

That said, the colour of the pepper matters nutritionally, the skin can be difficult to digest for some dogs, and there are several pepper varieties that should never be given to dogs. Here’s the complete guide.
Are Bell Peppers Good for Dogs?
Bell peppers offer an impressive nutritional profile for a low-calorie vegetable:
Vitamins A, C, and E
Vitamin A supports healthy vision, skin, coat condition, and immune function. Vitamin C acts as an antioxidant and supports immune response and tissue repair. Vitamin E is a fat-soluble antioxidant that supports cell membrane integrity and immune health. Getting all three in a single vegetable treat is a genuinely useful outcome. Dr. Chyrle Bonk DVM, a veterinary consultant, confirms that bell peppers contain vitamins C, A, and E alongside antioxidants that can help with chronic illness and slow the progression of ageing.
Beta-Carotene and Lycopene
Beta-carotene — the compound that gives red and orange peppers their vivid colour — converts to vitamin A in the body and supports eye health, skin condition, and immune resilience. Lycopene is a powerful antioxidant associated with reduced oxidative stress and potential protective effects against certain cancers. Both are present in higher concentrations in ripe red bell peppers than in any other colour variety.
Vitamin B6
Vitamin B6 supports brain health, hormone regulation, immune function, red blood cell production, and the metabolism of protein and carbohydrates. A useful micronutrient present in meaningful amounts in bell peppers.
Lutein
Lutein is a carotenoid specifically associated with eye health — it is concentrated in the retina and has been studied for its protective effects against age-related vision decline. Particularly relevant for older dogs or breeds with known eye health concerns.
Dietary Fibre
Bell peppers provide both soluble and insoluble fibre, supporting digestive regularity and gut microbiome health. The fibre content also helps promote satiety — a useful quality for dogs on calorie-managed diets.
Hydration
Bell peppers are high in water content — around 92% water — making them a naturally hydrating treat. Particularly useful during warm weather. In Spain where temperatures regularly exceed 35°C through summer, water-rich vegetables like bell peppers make a useful addition to the treat rotation for keeping dogs hydrated.
Very Low in Calories
A medium red bell pepper contains around 31 to 40 calories. This makes bell peppers one of the most generous treat options by volume without meaningfully impacting daily calorie intake.
Does the Colour Matter?
Yes — and this is one of the more genuinely useful distinctions in vegetable treat nutrition.
Red bell peppers — the best choice for dogs. Red bell peppers have spent the longest time on the vine, which means they’ve had the most time to develop their full nutritional profile. They contain three times more vitamin C than green peppers, the highest beta-carotene and lycopene content of any colour, and the richest antioxidant profile. Dr. Carly Fox DVM recommends red bell peppers as the most nutritious choice. If you’re choosing just one colour, choose red.
Yellow and orange bell peppers — excellent alternatives. Nutritionally between green and red, they offer a milder, sweeter flavour that some dogs find more appealing than the slight bitterness of red peppers. High in vitamin C and antioxidants, lower in beta-carotene than red.
Green bell peppers — safe, but the least nutritious option and the one to approach with most caution. Green peppers are unripe versions of red peppers — they have not yet completed ripening and their nutritional development is incomplete. They contain lower levels of vitamins and antioxidants than ripe varieties. More importantly, green peppers contain higher levels of solanine — a glycoalkaloid compound (the same family found in tomatoes and other nightshade family members) that in larger amounts can cause gastrointestinal upset. The amount in a small serving of green pepper is unlikely to cause problems for most dogs, but it’s a reason to prefer ripe peppers when you have the choice.
PetMD confirms that all bell pepper colours are safe in moderation — but the nutritional and digestibility advantages of ripe red, yellow, and orange peppers make them the better default choice.
The Critical Distinction — Bell Peppers vs Hot Peppers
This is essential to understand clearly.
Bell peppers (also called sweet peppers or capsicums) contain zero or negligible capsaicin — the compound responsible for the heat in spicy peppers. This absence of capsaicin is precisely why bell peppers are safe for dogs. They provide the nutritional benefits of the Capsicum genus without any of the irritating heat.
Hot peppers of any variety — jalapeños, chilli peppers, habaneros, cayenne, serrano, and anything described as spicy — contain capsaicin in varying concentrations and should never be given to dogs. Capsaicin causes significant gastrointestinal irritation in dogs — burning of the mouth and tongue, excessive drooling, vomiting, diarrhoea, and abdominal pain. Dogs have no tolerance for capsaicin and no evolutionary reason to have developed one.
This distinction also applies to seasonings and sauces containing capsaicin or capsaicin-derived products: chilli powder, paprika (hot variety), cayenne powder, and hot sauce. None of these should ever be given to dogs.
Sweet smoked paprika in tiny amounts is generally tolerated — but there’s no good reason to season a dog’s food, so simply don’t.
Seeds, Stem, and Skin — What to Remove
Seeds — the seeds inside a bell pepper are not toxic but can cause digestive irritation in some dogs, particularly those with sensitive stomachs. PetMD and Dr. Carly Fox DVM both recommend removing seeds before serving. This is especially worth doing for dogs who are new to bell pepper or who have a history of digestive sensitivity.
Stem — remove entirely. The stem is tough, fibrous, and a potential choking hazard. No nutritional value.
Skin — the outer skin of a raw bell pepper can be tough and difficult to digest for some dogs. Dr. Chyrle Bonk DVM notes that while a couple of thin raw slices with the skin on is unlikely to cause problems, for dogs who are going to eat bell pepper regularly, steaming or lightly sautéing the pepper softens the skin and improves digestibility significantly. Dogs with sensitive stomachs should always be given skinned or steamed bell pepper rather than raw.
How Much Bell Pepper Can a Dog Eat?
Given how low in calories bell peppers are, they’re one of the more generous treat options by volume. Dr. Carly Fox DVM recommends:
- Large dogs — up to half a bell pepper
- Small dogs — up to a quarter of a bell pepper
These are per-serving guidelines, not daily maximums. Bell pepper a few times a week is perfectly appropriate for most healthy adult dogs. The 10% daily calorie rule applies as always — though given how few calories bell pepper contains, this is very easy to stay within.
Introduce gradually when giving bell pepper for the first time — start with a single small piece and monitor for any digestive reaction before offering more.
Raw or Cooked — Which Is Better?
Raw bell pepper — retains the maximum vitamin and antioxidant content. Provides the crunchy texture most dogs enjoy. The tougher skin may be harder to digest. Fine for dogs with no digestive sensitivity.
Steamed bell pepper — the best option for dogs with sensitive stomachs, older dogs, or puppies. Softens the skin considerably, improves digestibility, retains more nutritional value than boiling. Serve plain, cooled to room temperature.
Lightly sautéed bell pepper — only if cooked in a tiny amount of dog-safe oil (such as a small amount of coconut oil) with absolutely no seasoning, garlic, onion, or butter. The fat content added even by a small amount of oil creates some pancreatitis risk — steaming is a safer cooking method.
Roasted bell pepper — safe if plain and cooled, but often prepared with oil and seasoning for human consumption. Only give if you know it was prepared completely plain.
Never give bell pepper that has been cooked with garlic, onion, salt, or butter. Garlic and onion are toxic to dogs. Salt creates sodium overload risk. Butter adds unnecessary fat with pancreatitis risk. Fajita mix, stir-fry, or any seasoned preparation is off the menu for your dog entirely.
Can Puppies Eat Bell Peppers?
Yes — bell peppers are safe for puppies and are a good early vegetable introduction given their mild flavour, soft texture when steamed, and excellent nutritional profile. Start with a very small amount, ensure seeds and stem are removed, and consider steaming the pepper to soften the skin for young puppies whose digestive systems are still developing.
Can Senior Dogs Eat Bell Peppers?
Absolutely — and the lutein content in particular makes bell peppers a worthwhile treat for older dogs where eye health maintenance becomes increasingly important. The anti-inflammatory antioxidant properties may also offer modest benefit for dogs with joint stiffness. Steamed rather than raw is the better preparation for senior dogs with dental issues or reduced digestive efficiency.
How to Serve Bell Peppers to Your Dog
Raw slices — wash, remove stem and seeds, slice into appropriately sized pieces. Simple and quick. Most dogs enjoy the crunch.
Steamed pieces — steam plain until just tender, cool completely, serve. Better for sensitive stomachs and senior dogs.
As a food topper — dice finely and mix into your dog’s regular food. Adds colour, nutrition, and variety without the dog needing to be interested in the pepper as a standalone treat.
Stuffed with dog-safe fillings — a small amount of plain cream cheese or xylitol-free peanut butter inside a bell pepper ring makes an appealing interactive treat for dogs who might not otherwise show interest in plain pepper.
Frozen pepper pieces — particularly good in warm weather. Cut raw pepper into pieces, freeze on a tray, serve from the freezer. A refreshing and hydrating summer treat.
Pureed into homemade treats — blended bell pepper (particularly red) can be incorporated into homemade dog treat recipes. Adds nutritional value and a mild natural colour without overpowering the flavour.
Signs Your Dog Has Had Too Much Bell Pepper
Bell peppers are very unlikely to cause serious harm, but too much at once can cause digestive upset:
- Loose stools or diarrhoea
- Vomiting
- Gas or bloating
- Loss of appetite
Mild symptoms should resolve within 24 hours. Reduce the amount given going forward and contact your vet if symptoms persist or worsen.
The Bottom Line
Bell peppers are one of the most straightforwardly positive vegetables you can share with your dog — confirmed safe by Dr. Carly Fox DVM and PetMD, nutritionally rich particularly in the red variety, low in calories, and genuinely enjoyable for most dogs. Remove seeds, stem, and skin where possible, serve plain without any seasoning, and red over green where you have the choice.
The only firm rules are: sweet bell peppers only, never hot peppers of any kind, and never seasoned or cooked with garlic, onion, or butter.
