Potatoes are used as a carbohydrate source in dog food, particularly in grain-free formulas. They provide starch for energy but have limited nutritional value beyond carbohydrates.
Nutritional Content
- Starch: Primary component, provides energy
- Vitamin C: Some antioxidant benefit
- Potassium: Supports heart and muscle function
- Vitamin B6: Aids metabolism
- Fiber: Minimal unless skin is included
Forms in Dog Food
- Potatoes: Whole potatoes
- Potato starch: Concentrated starch
- Potato protein: Extracted protein component
- Dehydrated potatoes: Dried form
Considerations
Limited nutrition: Compared to sweet potatoes or whole grains, white potatoes offer fewer vitamins and less fiber.
DCM investigation: Potatoes are among the ingredients the FDA has examined in connection with dilated cardiomyopathy (DCM) in dogs. They're often used alongside peas and lentils in grain-free formulas under investigation.
Glycemic impact: White potatoes have a higher glycemic index than sweet potatoes or whole grains, causing faster blood sugar spikes.
When Potatoes Are Used
Potatoes appear in dog food:
- As a grain-free carbohydrate option
- In limited ingredient diets
- When other carb sources cause sensitivities
Better Alternatives
For most dogs, consider foods with:
- Sweet potatoes (more nutrients, lower glycemic)
- Whole grains like brown rice or oats
- Varied carbohydrate sources
