Is Potato Safe for Dogs?
The AKC confirms potatoes “aren’t categorically toxic to dogs, like grapes or onions” and that they contain vitamins and minerals dogs need — including vitamin C, vitamin B6, iron, and magnesium. However, “you should never feed your dog a raw potato,” the AKC states clearly.
Raw potatoes belong to the nightshade family and contain solanine — a compound toxic to dogs. Cooking reduces solanine levels significantly, making cooked potato safe. Green potatoes and potato skins have higher solanine concentrations and should always be avoided.
The AKC also notes that dogs with diabetes should avoid potatoes entirely, as potatoes can cause blood sugar to spike. And like all carbohydrates, too much potato can contribute to obesity.
Nutritional Profile
| Nutrient | Benefit for Dogs |
|---|---|
| Vitamin C | Antioxidant support |
| Vitamin B6 | Supports metabolism and immune function |
| Iron | Supports red blood cell health |
| Magnesium | Supports muscle and nerve function |
| Carbohydrates | Digestible energy — use as occasional treat only |
Risks and What to Watch For
Raw potato contains solanine — toxic to dogs and potentially causing neurological and gastrointestinal symptoms. Green potatoes and potato skins have higher solanine. Too many carbohydrates from potatoes can cause obesity. Potatoes cooked with butter, salt, or cheese add fat and sodium that are unhealthy for dogs.
- Vomiting or diarrhea from raw potato solanine
- Weakness, confusion, or slow heart rate (solanine toxicity)
- Blood sugar spikes in diabetic dogs
- Weight gain from excess carbohydrates
How to Serve Potato to Your Dog
Bake or boil plain — no skin, no salt, no butter, no toppings of any kind. Let cool completely. Serve as a small occasional treat. The AKC suggests treating potato like any treat — small portions, not a staple.
| Dog Size | Weight Range | Serving Size |
|---|---|---|
| Extra Small | Under 10 lbs | ½ tsp plain cooked |
| Small | 10–25 lbs | 1 tsp plain cooked |
| Medium | 25–60 lbs | 1 tbsp plain cooked |
| Large | 60–100 lbs | 2 tbsp plain cooked |
| Extra Large | Over 100 lbs | Up to 3 tbsp plain cooked |
Common Potato Scenarios
Can Dogs Eat Raw Potato?
No. The AKC is clear: “you should never feed your dog a raw potato.” Raw potatoes contain solanine, which is toxic. Always cook first.
Can Dogs Eat Potato Skin?
No. Potato skins have higher solanine concentration than the flesh. Always peel before cooking and serving.
Can Dogs Eat French Fries or Chips?
No. The AKC specifically calls these out — fried in oil, loaded with salt, and sometimes seasoned with garlic or onion powder. Not appropriate for dogs.
Can Diabetic Dogs Eat Potato?
No. The AKC recommends avoiding potatoes entirely for diabetic dogs due to blood sugar spikes.
Are Sweet Potatoes Better Than White Potatoes?
Yes — the AKC notes sweet potatoes are “a healthier option” with more vitamins and nutrients. If you want to give your dog a potato treat, sweet potato is the better choice.
When to Call the Vet
- Dog ate raw or green potato — monitor for vomiting, weakness, or neurological signs
- Diabetic dog ate a significant amount of potato
- Vomiting or lethargy after eating potato
Bottom Line
Plain boiled or baked potato (no skin, no toppings) is safe for healthy dogs in small amounts. Raw potato is toxic — never feed it. Green potato and potato skin also have elevated solanine. Diabetic dogs should avoid potatoes. Sweet potato is a healthier alternative.

Can puppies eat potatoes?
Only plain cooked potato in a very small amount. Puppies are more sensitive to solanine and have specific nutritional needs — not recommended as a regular treat. Consult your vet.
