Can Dogs Eat Potatoes?

Can Dogs Eat Potatoes?

Dogs can eat potatoes, but they must be cooked properly and served in moderation. Raw potatoes, especially green ones, contain solanine, a compound that can be toxic to dogs. Once cooked, potatoes lose their solanine content and can offer nutritional benefits when added as a part of a balanced diet. However, it’s essential to serve them plain, without any added salt, butter, or seasonings.

Nutritional Value

Potatoes provide several nutrients beneficial for dogs, including:

  • Carbohydrates: Provide energy for active dogs.
  • Vitamin C: Supports the immune system and acts as an antioxidant.
  • Vitamin B6: Important for brain health and metabolism.
  • Minerals: Such as potassium, which is vital for maintaining fluid balance and nerve function.

Here’s a comparison of the nutritional content of potatoes to the average daily nutritional requirements for dogs of different sizes. This highlights the role potatoes can play in a dog’s diet when served appropriately.

This table demonstrates that while potatoes can provide energy and nutrients, they must be balanced with high-protein foods and served in moderation to maintain a healthy diet for dogs.

Food Suitability

Cooked, plain potatoes are suitable for most dogs in moderation. They should never replace a significant portion of your dog’s regular diet, as dogs require protein-rich foods for optimal health. Avoid feeding dogs raw potatoes, potato plants, and green potatoes due to their solanine content.

Feeding Instructions

  • Cooking: Ensure potatoes are thoroughly cooked to reduce solanine levels; boiling or baking without any added ingredients is best.
  • Preparation: Peel potatoes to minimise solanine content further and cut them into appropriately sized pieces to prevent choking.
  • Portion Control: Offer small portions as part of a balanced diet, especially considering the high carbohydrate content.


  • Solanine Toxicity: Found in raw and green potatoes, solanine can cause vomiting, diarrhoea, and even neurological symptoms.
  • Weight Gain: Due to their high starch content, overfeeding potatoes can contribute to obesity.
  • Allergic Reactions: Although rare, some dogs may be allergic to potatoes.

Allergies and Sensitivities

Keep an eye out for signs of food allergies or sensitivities when eating new foods, which may include itching, digestive upset, or lethargy. If you observe any adverse reactions after feeding your dog potatoes, it’s advisable to remove them from the diet and consult with a veterinarian.

Alternatively, you can use a dog sensitivity test to find out if your dog has any intolerances before feeding them new foods. 

Alternatives to Potatoes

If you're looking for alternative sources of carbohydrates or vegetables that can be safely included in your dog's diet, consider these nutritious options:

  • Sweet Potatoes: Rich in fibre, vitamins A, C, and B6, and minerals like manganese. They're a healthier alternative due to their lower glycemic index and higher nutrient content.
  • Pumpkin: High in fibre and vitamin A, pumpkin can help with digestive health and is a great low-calorie treat.
  • Carrots: Low in calories and high in fibre and vitamin A, carrots are an excellent crunchy treat for dogs, promoting dental health.


Can dogs eat potato skins?

Potato skins can contain higher levels of solanine, especially if they are green or sprouted. It’s best to peel potatoes before cooking them for your dog to reduce the risk of solanine toxicity.

How much potato can I feed my dog?

Potatoes should be fed in moderation, making up a small portion of your dog’s diet. As a guideline, a small piece of cooked potato can be offered as an occasional treat, not exceeding more than 10% of their daily food intake.

Are there any dogs that should avoid potatoes?

Dogs with diabetes or weight issues should avoid potatoes due to their high carbohydrate and sugar content. Always consult with a veterinarian before introducing new foods to your dog’s diet, especially if they have preexisting health conditions.

Portion Sizes (Table Format)

To safely incorporate potatoes into your dog's diet, adhere to these portion size recommendations. These are intended for potatoes as an occasional treat, not a staple of their daily intake.

Dog Size

Suggested Portion


1-2 small pieces (about 1-2 teaspoons)


2-3 medium pieces (about 1 tablespoon)


3-4 large pieces (about 2 tablespoons)

Remember, these portions should be adjusted based on your dog’s overall diet and caloric needs, ensuring that treats do not make up more than 10% of their daily calorie intake.


Cooked, plain potatoes can be a safe and occasional treat for dogs when prepared correctly and served in moderation. They offer a source of carbohydrates, vitamins, and minerals that can complement a balanced diet. However, due to concerns like solanine toxicity, weight gain, and potential allergies, it’s crucial to introduce potatoes slowly and monitor your dog for any adverse reactions. Alternatives like sweet potatoes, pumpkin, and carrots can provide similar nutritional benefits with fewer risks.
