Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
Brief Answer
Cooked, plain potatoes are safe for dogs in moderation. However, raw potatoes and green-skinned potatoes contain solanine, which is toxic to dogs. Always cook potatoes thoroughly and never serve them green or sprouting.
The Full Picture
Plain, cooked potatoes (baked, boiled, or mashed without butter or seasoning) are safe for dogs in moderation. However, raw potatoes and green potatoes contain solanine, a compound that is toxic to dogs. Always cook potatoes thoroughly and never feed green-skinned or sprouting potatoes. Fried potatoes (chips, crisps) are unhealthy due to salt and oil. Potatoes are high in carbohydrates, so they should be a small part of the diet, not a staple.
Nutritional Highlights
- Good source of vitamin C and vitamin B6
- Contains potassium and iron
- Provides carbohydrates for energy
- Contains fibre when served with skin (after cooking)
How to Prepare Potatoes for Dogs
- Always cook potatoes thoroughly — bake, boil, or steam until soft
- Never feed raw, green, or sprouting potatoes
- Remove green-tinged skin or discard green potatoes entirely
- Serve plain without butter, salt, sour cream, or seasoning
- Mashed potato (plain, no dairy) is the easiest form for dogs to digest
How Much Potatoes Can Dogs Eat?
A few small cubes of plain, cooked potato is fine as an occasional treat. Potatoes are high in carbohydrates, so they should not be a dietary staple, particularly for overweight or diabetic dogs.
Signs to Watch For
- Solanine poisoning from raw/green potatoes: vomiting and diarrhoea
- Lethargy and weakness
- Confusion and disorientation in severe cases
- Gastrointestinal inflammation and abdominal pain
What You Should Know
Although not outright toxic, there are important precautions to bear in mind before sharing potatoes with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
Common Questions About Dogs and Potatoes
- Why are raw potatoes dangerous for dogs?
- Raw potatoes contain solanine, a toxic glycoalkaloid concentrated in the skin and especially in green or sprouting areas. Cooking destroys most of the solanine, making the potato safe.
- Can dogs eat chips or crisps?
- No. Chips and crisps are fried in oil and heavily salted, making them unhealthy for dogs. Stick to plain baked, boiled, or steamed potato.
- Are sweet potatoes better than white potatoes for dogs?
- Sweet potatoes are generally considered a better choice — they contain more vitamins, more fibre, and do not carry the solanine risk that raw white potatoes do.
