Can dogs eat mashed potatoes?

Mashed potatoes made from plain boiled potatoes without salt, butter and milk are fine for dogs. Store-bought mashed potatoes often contain additives dogs can't tolerate, and nutmeg is even toxic. Better: simply boil the potatoes and mash them. As a bland diet for diarrhea, it makes a good side dish.

Quick answer
  • Yes, homemade mashed potatoes are fine for dogs
  • Prepare it without milk, butter or seasoning
  • Boiled potatoes are easy to digest

Yes, homemade mashed potatoes without additives are fine for dogs. Raw potatoes, on the other hand, are toxic because they contain solanine. Store-bought instant mashed potato products almost always contain salt, milk or seasoning and are not suitable.

What mashed potatoes can do for dogs

Boiled potatoes provide vitamin C, potassium and iron, along with dietary fiber. For a sensitive stomach or mild digestive problems, boiled potatoes work well as an easy-to-digest side dish. As a bland diet after diarrhea, they can help settle the digestive tract.

What to watch out for

Raw potatoes are toxic for dogs: they contain solanine, which can cause stomach problems. Always cook potatoes through completely.

Don't make mashed potatoes with salt, butter, milk, onions or seasoning, as these ingredients harm dogs. Onions are toxic even in small amounts.

Don't feed instant products: they almost always contain problematic additives.

How to prepare mashed potatoes

Peel the potatoes and boil them in unsalted water until soft. Mash them with a fork or a potato masher. If you want to make the mash tastier, stir in a little unsalted chicken broth. Let it cool down completely and serve it as a small side with your dog's food.

Nutritional values and amount

100 g of boiled potatoes (without additives) contains about 70 kcal, 1.7 g protein, 15 g carbohydrates, 0.1 g fat, as well as 330 mg potassium and 12 mg vitamin C.

Guideline amounts for homemade mashed potatoes as a side:

  • Small dogs (up to 10 kg): 1 to 2 tablespoons
  • Medium dogs (10 to 25 kg): 2 to 3 tablespoons
  • Large dogs (over 25 kg): 3 to 4 tablespoons

As a bland diet, feed it for 2 to 3 days at most, then switch back to regular food. Store leftover mashed potatoes in the fridge and use them within 2 days.
