Cook the sweet potato. Peel the sweet potato and cut it into small cubes. Boil or steam for about 10–15 minutes, or until a fork slides through easily. Drain and allow it to cool completely.

Mash the sweet potato. Mash the cooked sweet potato until smooth. Remove any firm pieces so the frozen treat has an even texture.

Blend the ingredients. Add the mashed sweet potato, plain yogurt, and peanut butter to a blender or food processor. Blend until creamy. Add one tablespoon of water if the mixture is too thick to blend.

Check the consistency. The mixture should be thick but easy to spoon into molds. Add a little more water only if necessary.

Fill the molds. Spoon the mixture into a silicone mold or ice cube tray. Make small portions appropriate for your dog's size.

Freeze until firm. Place the molds on a level freezer shelf and freeze for at least 3 hours, or until the portions are completely solid.

Remove and store. Once frozen, pop the treats out of the molds and transfer them to an airtight freezer-safe container.

Serve safely. Offer one small portion at a time. Let it soften slightly if it is too firm, and supervise your dog while eating.

Choose safe yogurt: I use plain, unsweetened yogurt without xylitol or other sweeteners. Some dogs have difficulty digesting lactose, so start with a small amount and discontinue if it causes digestive upset.

Check the peanut butter label: Always confirm that the peanut butter is xylitol-free. Avoid products containing chocolate or other ingredients unsafe for dogs.

Cook the sweet potato thoroughly: Raw sweet potato can be difficult for dogs to chew and digest. Cooking it until tender makes it easier to mash and blend.

Storage: Keep the treats frozen in an airtight container and use within about 2 months for best quality. Thaw only the portion you plan to serve, and discard any treat that has been contaminated or left out too long.

Common mistake to avoid: Freezing the mixture before blending it smoothly can leave hard chunks in the finished treat. Mash the sweet potato well and blend everything before filling the molds.

Serving tip: These treats are intended for occasional enjoyment, not as a meal replacement. Start with a small serving, especially if your dog has not tried yogurt or peanut butter before.

Dietary considerations: Sweet potato contains carbohydrates, and peanut butter adds fat and calories. Keep portions small, particularly for dogs on weight-management diets or those with a history of pancreatitis. Ask your veterinarian whether these ingredients suit your dog's individual needs.
