Step-by-Step Instructions

  • First, preheat your oven to 375°F (190°C). Then, line a baking sheet with parchment paper. This stops them from sticking.
  • Next, prepare the sweet potato. You can boil, steam, or microwave it until it’s very soft. Peel it after cooking.
  • Mash the cooked sweet potato thoroughly in a medium bowl. Make sure there are no lumps.
  • Drain the canned tuna very well. You want to get rid of as much water as possible.
  • Add the drained tuna to the mashed sweet potato.
  • Mix the tuna and sweet potato together until they are well combined. You’re looking for a consistent texture here.
  • Roll the mixture into small, bite-sized balls. Aim for about ½ to ¾ inch in diameter, depending on your dog’s size.
  • Place the balls on the prepared baking sheet.
  • Bake for 20-25 minutes, or until the treats are firm and slightly golden brown. They should be cooked through.
  • Let the treats cool completely on a wire rack before serving to your dog.

Look, prepping and cooking for your dog is great, but sometimes you might be too tired or maybe a tad lazy, or maybe you just want to give yourself a well deserved break.

Feeding Guidelines

  • Small Dogs (under 20 lbs): 2-3 treats per day as a supplement.
  • Medium Dogs (20-50 lbs): 4-6 treats per day.
  • Large Dogs (over 50 lbs): 6-8 treats per day.
  • For puppies or very active adult dogs, a slightly higher amount might be okay. But here’s the thing, treats should only be about 10% of their daily caloric intake.
  • If your dog has specific health conditions or is pregnant/nursing, it’s always best to talk to your vet first. They can give you personalized advice.

Common Questions & Troubleshooting

Can I use fresh tuna instead of canned?

Yes, you can. Just make sure it’s plain, cooked tuna without any seasonings or oils. And here’s the thing, always ensure there are no bones.

My dog has allergies. Is this recipe safe?

This recipe is often good for dogs with common chicken or grain allergies. But if your dog has specific fish or sweet potato allergies, then no. Always check with your vet if you’re unsure.

Why are my treats crumbly?

This often happens if the sweet potato wasn’t mashed well enough or if the tuna wasn’t drained completely. Make sure both ingredients are very well combined to help them bind.

Can I add other ingredients?

Keep it simple for this recipe. But you can add a tiny bit of dried parsley for fresh breath if you want. It’s important to keep the ingredient list short for sensitive dogs.
