How much potato for your dog?
Most guides say "a few pieces". Enter your dog's weight and get the actual daily ceiling, worked out from potato's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for dogs
Plain cooked potato is fine, but raw and green potato contains solanine, which is toxic to dogs.
Plain, fully cooked potato is safe for most dogs and cats in small amounts — but raw or green potato contains solanine, and fries and chips bring the salt-and-oil problem.
How much is safe?
A small portion of plain boiled, baked or mashed potato (no butter, milk, salt or seasoning) is fine occasionally. It's dense in carbs, so keep portions small — especially for less active or overweight pets.
What happens if a dog eats too much?
Raw potato — and any potato with green skin or sprouts — contains solanine, which can cause vomiting, drooling and weakness; peeling and full cooking removes the risk from normal potatoes. Fries, chips and loaded potatoes add oil, salt and often onion or garlic.
How to serve it safely
Peel, cook thoroughly (boil or bake), and serve plain in small cubes or a spoonful of plain mash. Discard green or sprouted potatoes entirely.

Frequently asked questions
Can pets eat raw potato?
No — raw potato contains solanine, especially in green skin and sprouts. Only plain, fully cooked potato is safe.
Are mashed potatoes ok?
Only if plain — typical mash has butter, milk and salt, and holiday versions often add garlic. A spoonful of plain mash is fine.
Can pets eat sweet potato instead?
Yes — plain cooked sweet potato is actually the more nutritious choice, rich in fiber and beta-carotene.
