Can Dogs Eat Potatoes?
Yes, dogs can eat potatoes, but only when they are prepared correctly and offered in small amounts. A small piece of plain, cooked potato is usually fine for a healthy dog as an occasional treat. The primary concerns involve how the potato is prepared and which parts of the plant are consumed.
Many popular potato dishes made for humans, such as french fries or mashed potatoes, contain added ingredients that are not suitable for dogs. Additionally, raw potatoes and the green parts of the potato plant are unsafe for dogs to eat.

What makes potatoes tricky for dogs
The main risk with potatoes comes from solanine, a compound found in raw potatoes. This substance is present in the green parts of the plant, including the skin if it has a green tinge, the sprouts, and the leaves. Cooking the potato helps reduce the risks associated with it.
Another concern is the way potatoes are often prepared for people. Dishes like french fries, potato chips, and loaded mashed potatoes are high in fat and salt. They may also contain other ingredients that are not good for dogs, such as butter, milk, or garlic. These rich, fatty foods can lead to digestive upset.
How to serve potatoes safely
If you choose to share potato with your dog, it must be prepared properly. Always start with a fresh, ripe potato and wash it thoroughly. It is important to remove the peel, especially if there are any green spots.
The safest ways to prepare it are by boiling or baking it. Follow these guidelines:
- Cook it completely. Never serve raw potato.
- Keep it plain. Do not add salt, butter, oil, milk, cheese, or any other seasonings.
- Serve in moderation. A small amount is all a dog needs. Cut it into bite-sized pieces to prevent choking.
Always avoid serving dishes like potato chips, french fries, or seasoned mashed potatoes. When considering any food for your pet, it is a good practice to read the ingredient label to check for anything that might be harmful.
When to skip giving your dog potatoes
Plain, cooked potato should only be given as an occasional treat, not as a regular part of a dog’s diet. It is a starchy vegetable, and it is best to avoid giving it to dogs who need to manage their weight. If your dog has any underlying health conditions, it is always wise to consult your veterinarian before introducing new foods into their diet.
Even for healthy dogs, too much of a new food can cause an upset stomach. When offering potato for the first time, give only a very small piece and watch for any signs of digestive trouble like vomiting or diarrhea. If you notice any issues, it is best to avoid giving them potatoes in the future.
When to call your vet
Most dogs who eat a little plain potatoes need nothing more than watching. Call your vet if anything below shows up, or if your dog has a health condition or is on a special diet.
If your dog eats raw potato, green potato skin, or sprouts, contact your veterinarian or the ASPCA Animal Poison Control Center for guidance. Note what part of the plant was eaten, how much, and when. You should also call your vet if your dog shows signs of a sore belly, vomiting, or diarrhea after eating any amount of potato.
