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 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, vital for maintaining fluid balance and nerve function.
Here's a comparison of the nutritional content of potatoes to the average daily requirements for dogs of different sizes:
| Nutrient | Value per 100g of potato | Small dogs (1–10kg) daily requirement* | Medium dogs (11–26kg) daily requirement* | Large dogs (27kg+) daily requirement* |
| Calories | ~77 kcal | 200–400 kcal | 400–800 kcal | 800–1,600 kcal |
| Carbohydrates | ~17g | Varies (low-carb diet preferred) | Varies | Varies |
| Protein | ~2g | 25–50g | 50–75g | 75–100g |
| Fibre | ~2.2g | 1.5–3g | 3–4.5g | 4.5–6g |
| Vitamin C | ~12.6mg | 25–50mg | 50–75mg | 75–100mg |
| Vitamin B6 | ~0.3mg | 0.18–0.55mg | 0.55–1.1mg | 1.1–2.2mg |
| Potassium | ~421mg | >0.6% dietary intake | >0.6% dietary intake | >0.6% dietary intake |

This table shows 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 added ingredients is best.
- Preparation: peel potatoes to further reduce solanine content, and cut into appropriately sized pieces to prevent choking.
- Portion control: offer small portions as part of a balanced diet, especially given the high carbohydrate content.
Risks
- 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 trying new foods, which may include itching, digestive upset, or lethargy. If you notice any adverse reaction after feeding your dog potatoes, it's advisable to remove them from the diet and consult your veterinarian.
Alternatively, you can use a dog intolerance 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 — a healthier alternative thanks to their lower glycaemic 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 that also promotes dental health.
FAQs
Can dogs eat potato skins?
Potato skins can contain higher levels of solanine, especially if 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 your veterinarian before introducing new foods, especially if your dog has a pre-existing health condition.
Portion Sizes
To safely incorporate potatoes into your dog's diet, follow these portion size recommendations. These are intended for potatoes as an occasional treat, not a staple of their daily intake.
| Dog size | Suggested portion |
| Small | 1–2 small pieces (about 1–2 teaspoons) |
| Medium | 2–3 medium pieces (about 1 tablespoon) |
| Large | 3–4 large pieces (about 2 tablespoons) |
Remember, these portions should be adjusted based on your dog's overall diet and calorie needs, ensuring that treats don't 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 reaction. Alternatives like sweet potatoes, pumpkin, and carrots can provide similar nutritional benefits with fewer risks.
