How to prepare and serve
Preparation
Wash, peel, and cut into cubes. Boil, steam, or bake until soft — never serve raw. Mash or cut into small pieces. Plain only — no butter, brown sugar, marshmallows, cinnamon, or nutmeg. Sweet potato fries are too oily and salty. Dehydrated sweet potato slices make an excellent homemade chew treat — bake thin slices at 250°F for 2-3 hours.
Frequency
2-3 times per week as a treat or food topper.

Frequently Asked Questions
- Sweet potatoes are generally considered superior to white potatoes for dogs. They have a lower glycemic index, meaning they cause a slower, steadier rise in blood sugar rather than a sharp spike. Sweet potatoes also contain significantly more beta-carotene, vitamin A, and antioxidants. White potatoes are safe when cooked but offer less nutritional variety. One important note: raw white potatoes contain solanine, a toxic compound — they must always be cooked. Sweet potatoes don't have this concern but should still be cooked for digestibility.
- Homemade dehydrated sweet potato chews are one of the best DIY dog treats you can make. Wash, peel, and slice sweet potatoes into 1/4-inch thick rounds or strips. Place on a parchment-lined baking sheet and bake at 250°F (120°C) for 2-3 hours, flipping halfway, until they're dry and slightly chewy. No seasoning, oil, or sugar needed. These make excellent chew treats that are much healthier and cheaper than store-bought alternatives. Store in an airtight container for up to two weeks, or freeze for longer storage.
- Sweet potato should make up no more than 10% of your dog's daily caloric intake, following the standard treat rule. For a 30-pound dog eating about 800 calories per day, that's roughly 2-3 tablespoons of cooked sweet potato. Because sweet potatoes are relatively calorie-dense for a vegetable (86 kcal per 100 g), portions should be modest. Dogs with diabetes or weight issues should eat even less due to the natural sugar and carbohydrate content. Start with a small amount and increase gradually to avoid digestive upset.

Beets
CautionCooked beets are safe in small amounts, but high in sugar and oxalates. Avoid for dogs with kidney issues.
