Sweet potato chews are one of the simplest and most popular homemade dog treats. They need just one ingredient, cost far less than store-bought versions and come out chewy, naturally sweet and satisfying. Slice, bake low and slow, and you have a jar of chews that keep your dog busy longer than a quick biscuit.
This guide shows you how to make homemade sweet potato dog chews in the oven or a food dehydrator, how thick to slice for soft or firm chews, how to tell when they are done and how to store them so they don’t go moldy. It also covers how many to give and which dogs should skip them.

Why Sweet Potato Makes a Great Dog Chew
Sweet potato is naturally sweet, so dogs love it without any added sugar. It is a source of fiber and contains vitamin A precursors, and when dried slowly it becomes dense and chewy rather than crunchy. Because these chews contain nothing but sweet potato, they are a useful option for dogs with sensitivities to wheat, chicken or beef, though you should still check with your vet if your dog has a diagnosed allergy.
Unlike rawhide, sweet potato chews soften as they are chewed. They are not a long-lasting chew for heavy chewers, but they last much longer than a biscuit.
Choosing and Preparing Sweet Potatoes
Pick medium sweet potatoes that are firm, smooth and evenly shaped; long, straight potatoes make the most uniform strips. Scrub them well under running water. You can leave the skin on for extra texture, or peel it for a softer, smoother chew. Cut away any green, sprouted or damaged spots. Use a sharp chef’s knife or a mandoline with a hand guard so every slice is the same thickness, which is the key to even drying.
One-Ingredient Sweet Potato Dog Chews
Ingredients
- 2 medium sweet potatoes (about 1 1/2 lb / 680 g total), scrubbed

Instructions
- Heat the oven to 250°F (120°C) and line two baking sheets with parchment paper.
- Trim the ends of the sweet potatoes. Slice them lengthwise into planks 1/3 inch (8 mm) thick for chewy chews, or 1/4 inch (6 mm) for firmer, drier chews. Cut wide planks into strips about 1 inch (2.5 cm) wide.
- Arrange the slices on the sheets in a single layer without overlapping.
- Bake for 1 1/2 hours, then flip each piece.
- Continue baking for another 1 to 1 1/2 hours, until the chews are dry and leathery on the outside, slightly flexible and no longer moist in the center when you bend one.
- Turn off the oven and leave the chews inside for 1 hour with the door cracked to finish drying.
- Cool completely on the sheets before storing.
- Dehydrator method: arrange the slices on the trays and dry at 135°F (57°C) for 8–12 hours, checking from 8 hours.

Storage
Because they contain moisture, store sweet potato chews in an airtight container in the fridge for up to 2 weeks. Very dry, firm chews can stay at room temperature for up to 5 days. For longer storage, freeze them in a freezer bag for up to 3 months. Throw away any chew that develops white or green fuzzy spots or smells sour.
How to Tell When They Are Done
A finished chew should feel dry and slightly tacky on the surface, bend without snapping and show no wet, bright-orange flesh when you tear one open. If the center still looks moist, give the chews another 20–30 minutes. Edges that darken a little are fine, but blackened pieces should be discarded.
Soft vs Firm Chews
- Soft and chewy (best for seniors and small dogs): slice 1/3 inch (8 mm) thick, bake the shorter time and refrigerate.
- Firm (best for medium and large dogs): slice 1/4 inch (6 mm) thick, bake the full time and dry in the cooling oven.
- Crispy chips: slice 1/8 inch (3 mm) rounds and bake 2 hours, flipping once.
Flavor Ideas and Variations
Plain sweet potato is the safest choice, but you can vary the batch. Slice a few planks of butternut squash (peeled and seeded) or cored apple rings and dry them alongside the sweet potato on a separate tray, since they dry at different speeds. For a meaty twist, wrap a thin strip of plain raw chicken breast around each sweet potato plank before baking, then bake at 250°F (120°C) until the chicken is fully dry and has reached 165°F (74°C); these must be refrigerated and used within five days. Skip oil, salt, cinnamon blends and any seasoning.
Troubleshooting
Chews are burnt but still soft inside: your oven runs hot or the slices were uneven. Lower to 225°F (110°C) and extend the time. Chews went moldy: they weren’t dry enough or were stored warm and sealed. Refrigerate and use within two weeks. Chews are brittle: they were sliced too thin or overdried; reduce the time next batch.
How Many Sweet Potato Chews Can a Dog Have?
Sweet potato is starchy and higher in calories than most vegetables. One chew a day is plenty for a small dog and one or two for a large dog, as part of the 10% treat allowance. Introduce slowly, since the fiber can upset some stomachs. Always supervise chewing, and take away any small end piece that could be swallowed whole. Dogs with diabetes or weight issues should only have sweet potato chews if your vet agrees.

Dog Safety Notes
- Peanut butter: use only natural, unsalted peanut butter with no xylitol (check the label for “xylitol†or “birch sugarâ€). Choose unsalted and unsweetened.
- Never add: chocolate or cocoa, grapes, raisins or currants, onion, garlic, chives or leeks, macadamia nuts, nutmeg, alcohol, raw yeast dough, cooked bones, added salt or sugar, or artificial sweeteners.
- Fruit and veg prep: remove apple cores and seeds, use seedless watermelon without rind, and use plain unsweetened pumpkin puree (not pumpkin pie filling) and plain unsweetened yogurt.
- Portions: treats should make up no more than about 10% of your dog’s daily calories. Cut pieces to suit your dog’s size and supervise chewing.
- Check with your vet before introducing new foods if your dog has allergies, a sensitive stomach, diabetes, pancreatitis, kidney disease or is on a prescription diet. Introduce one new treat at a time.
Frequently Asked Questions
Are sweet potato chews safe for dogs?
Plain, fully cooked and dried sweet potato is safe for most dogs in moderation. Avoid raw sweet potato, seasoning and oil, and supervise chewing.
Should I peel sweet potatoes for dog chews?
Peeling is optional. Well-scrubbed skin adds texture; peeled chews are softer and smoother.
Can puppies have sweet potato chews?
Many puppies can have small pieces of soft chew once they eat solid food. Ask your vet first and avoid very hard, overdried chews for young teeth.
Why are my homemade sweet potato chews moldy?
They likely had too much moisture left inside. Dry them longer, cool fully before storing and keep them in the fridge.
