Can dogs eat potatoes?
The full picture
Like tomatoes, potatoes are nightshades and contain solanine — concentrated in the skin, sprouts, and any green parts. Cooking destroys much of the toxin, which is why plain boiled, baked, or steamed potato flesh is generally safe. Raw potato, green potato, or sprouted potato should never be fed. French fries, potato chips, and roast potatoes cooked with salt, oil, and seasonings are separate issues. A few pieces of plain cooked potato mixed into a meal is fine; a high-potato diet isn't ideal.

Symptom timeline
Symptoms typically progress in stages. Knowing what to expect helps you act fast:
- 2–6 hours If raw or green potato eaten: drooling, vomiting, diarrhea from solanine
- 6–24 hours Solanine in larger amounts: weakness, tremors, slow heart rate, confusion
- 24–72 hours Plain cooked potato: symptoms usually resolve; severe solanine cases may have persistent neurological signs
Safe portion size
A small amount of plain cooked potato occasionally.
Safer alternatives
- Cooked sweet potato
- Carrots
- Butternut squash
Common questions
My dog just ate a small amount of potatoes — what should I do?
A small accidental mouthful of potatoes is usually not an emergency, but it depends on your dog's size and what else was involved. Watch for vomiting, diarrhea, lethargy, or unusual behavior over the next 12–24 hours. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 if you see any symptoms or if your dog is small or young.
Why is potatoes risky for dogs?
Like tomatoes, potatoes are nightshades and contain solanine — concentrated in the skin, sprouts, and any green parts.

Chips, chips, and roast potatoes cooked with salt, oil, and seasonings are separate issues.
What's a safer alternative to potatoes?
See the alternatives section above. In general, plain cooked meat (no seasoning), plain vegetables like carrot or green bean, or dog-specific treats are always a safer choice than human foods with uncertain risk profiles.
Can potatoes make a dog sick long-term?
Repeated small exposures to potatoes can be worse than a single large accident, depending on the specific risk. Some foods cause cumulative damage (like onion/garlic affecting red blood cells over days), while others just cause repeat GI upset. If your dog has eaten potatoes multiple times, mention it to your vet at the next visit.
