Can dogs eat potatoes?
Last reviewed June 2026 · Sourced from ASPCA & Merck Veterinary Manual
The short answer
Sometimes — with caution — dogs should only have small amounts of potatoes. Cooked, plain only — never raw or green Starchy tuber, base of many cuisines.
Why be careful
Cooked plain potato is fine in moderation. Raw or green potatoes contain solanine, toxic to dogs.
Symptoms to watch for
Solanine toxicity: vomiting, diarrhea, drowsiness, confusion.
What every dog owner should know
- No green-tinted potatoes
- Skip butter, salt, seasoning
- Mashed potato 'as is' okay; mashed with butter/garlic NOT okay

Puppy safety
Generally avoid feeding potatoes to puppies. Their digestive systems are still developing and they're more sensitive to changes in diet, fat, sodium, and lactose than adults. If you've already given some, watch for vomiting, diarrhea, or lethargy and contact your vet if any appear.
What to do if your dog ate potatoes
- Note how much was eaten and when. A small amount is rarely an emergency, but a large quantity may need vet attention.
- Watch for symptoms over the next 12–24 hours: vomiting, diarrhea, lethargy, loss of appetite, or changes in drinking/urination.
- Provide fresh water and skip the next meal if your pet seems unsettled — let their stomach calm down.
- Call your vet if symptoms appear or persist beyond 24 hours, or if the amount eaten was significant.
