6 Easy Tuna Sweet Potato Dog Treats to Bake, Freeze, or Dry

Tuna sweet potato dog treats are one of the easiest homemade snacks you can make. Two simple ingredients, a few minutes of mixing, and your dog is spinning in circles by the kitchen counter.

Tuna brings the strong fishy smell dogs go wild for. Sweet potato adds soft texture, natural sweetness, and fiber. Together they make a snack that works for training, rewards, and rainy-day chewing.

The best part is that you do not have to make them just one way. This guide gives you six full recipes: soft baked biscuits, grain-free bites, frozen pupsicles, a stuffed KONG, dried jerky strips, and tiny training squares. Every recipe has its own copy-ready card with times, yield, ingredients, and steps.

If you love baking for your pup, you will also like these homemade dog treat recipes. Now let’s get cooking.

1. Soft Baked Tuna Sweet Potato Dog Treats

This is the classic. You mix mashed sweet potato, canned tuna, an egg, and oat flour into a soft dough. Then you roll it out, cut it into fun shapes, and bake until set.

The result is a biscuit that is firm on the outside and slightly soft in the middle. It is easy to break in half for small dogs. It also smells amazing while it bakes, so expect an audience.

Best for: First-timers, gift bags, and everyday rewards.

Recipe Card:

Prep Time: 20 minutes
Bake Time: 22 minutes
Freeze Time: Not needed
Yield: About 30 small biscuits (1½-inch size)

Ingredients

• 1 cup cooked, mashed sweet potato (about 1 medium potato, skin removed)
• 1 can (5 oz) tuna packed in water, drained
• 1 large egg
• 1½ cups oat flour, plus extra for dusting (blend plain rolled oats until powdery)
• 1 tablespoon chopped fresh parsley (optional)

Instructions

1. Heat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. In a large bowl, mash the sweet potato until smooth.
3. Add the drained tuna and egg. Mix well with a fork until the tuna breaks into tiny flakes.
4. Stir in the oat flour and parsley. The dough should feel soft and a little sticky but hold together.
5. Dust your counter with oat flour. Roll the dough about ¼ inch thick.
6. Cut shapes with a small cookie cutter. Place them on the baking sheet, close together, since they will not spread.
7. Bake for 20 to 24 minutes, until the edges look dry and the tops feel firm.
8. Turn off the oven and let the treats cool inside for 15 minutes. This helps them firm up.
9. Cool completely before serving.

Notes

• If the dough is too sticky, add 1 tablespoon of oat flour at a time. If it is too dry, add 1 tablespoon of water.
• For crunchier treats, bake 5 extra minutes and leave them in the cooling oven for an hour.
• Always check the tuna label. Pick tuna in water with no added salt, oil, or seasoning.

Pro tip: Use a bone-shaped cutter and roll the dough a bit thicker for a bigger “bone” style biscuit. Small dogs do best with pieces smaller than their mouth.

2. Grain-Free Tuna Sweet Potato Dog Treats

Some dogs do better without grains, and some owners just like a shorter ingredient list. This recipe skips flour completely. You only need tuna, sweet potato, and eggs.

You bake the mix in a mini muffin pan so every bite comes out the same size. They puff up a little, then settle into soft, moist rounds. Think of them as tiny savory muffins for dogs.

Best for: Dogs with grain sensitivities and owners who love short ingredient lists.

Recipe Card:

Prep Time: 15 minutes
Bake Time: 18 minutes
Freeze Time: Not needed
Yield: 24 mini bites

Ingredients

• 1 cup cooked, mashed sweet potato
• 1 can (5 oz) tuna packed in water, drained
• 2 large eggs
• 2 tablespoons coconut flour (optional, only if the batter looks too runny)
• Non-stick spray or a little coconut oil for the pan

Instructions

1. Heat the oven to 350°F (175°C). Lightly grease a 24-cup mini muffin pan.
2. Add the sweet potato, tuna, and eggs to a bowl.
3. Mash and stir until the tuna is flaked fine and the batter looks smooth.
4. If the batter drips off the spoon like soup, stir in the coconut flour. It should look like thick cake batter.
5. Fill each muffin cup about ¾ full.
6. Bake for 16 to 20 minutes, until the centers are set and a toothpick comes out clean.
7. Let the bites rest in the pan for 10 minutes, then lift them out with a spoon.
8. Cool completely on a wire rack.

Notes

• These are softer than biscuits, so store them in the fridge.
• For a firmer bite, bake 5 more minutes.
• A silicone mini muffin pan makes removal much easier.

Pro tip: Mix the batter in a food processor for 20 seconds. You get a super smooth texture that bakes evenly and looks like bakery treats.

3. Frozen Tuna Sweet Potato Dog Treats (Pupsicles)

No oven? No problem. These frozen tuna sweet potato dog treats are perfect for hot days, teething puppies, and dogs who love crunchy cold snacks.

You blend the ingredients into a thick puree, spoon it into molds, and let the freezer do the work. The treats pop out like little ice pops. Dogs usually lick them first, then crunch them down.

Best for: Summer, teething puppies, and quick no-bake snacking.

Recipe Card:

Prep Time: 15 minutes (use sweet potato that is already cooked and cooled)
Bake Time: None
Freeze Time: 3 to 4 hours
Yield: About 20 small cubes (1-tablespoon silicone molds or an ice cube tray)

Ingredients

• 1 cup cooked, mashed sweet potato
• 1 can (5 oz) tuna packed in water, with the water from the can
• ½ cup plain water (add more if needed)
• 1 tablespoon chopped fresh parsley (optional)

Instructions

1. Add the sweet potato, tuna, and the water from the can to a blender or food processor.
2. Pour in the plain water and the parsley.
3. Blend until smooth and thick, like a milkshake.
4. Pour or spoon the mix into silicone molds or an ice cube tray. Tap the tray on the counter to remove air bubbles.
5. Freeze for 3 to 4 hours, until solid.
6. Pop the treats out and store them in a freezer bag.
7. Serve one treat on a mat or tile, since they melt and can drip.

Notes

• Serve right from the freezer. Do not heat them up.
• Smaller cubes work for small dogs. Use a large mold for big dogs.
• Always watch your dog while they eat frozen treats.

Pro tip: Freeze the treats on a flat tray first, then move them to a bag. That stops them from sticking into one big block. These are also great for a dog treat station in your freezer drawer.

4. Stuffed KONG Tuna Sweet Potato Dog Treat

This one is less a “treat” and more a “dog puzzle.” You pack a KONG-style chew toy with a tuna and sweet potato mix, freeze it, and hand it over. Your dog will spend 20 to 30 minutes working for every last bit.

It keeps dogs busy while you work, helps with crate time, and burns off extra energy. The cold also feels good on sore gums.

Best for: Busy days, crate training, and dogs who need a brain game.

Recipe Card:

Prep Time: 10 minutes
Bake Time: None
Freeze Time: 4 hours or overnight
Yield: 1 medium KONG

Ingredients

• ½ cup cooked, mashed sweet potato
• 2 tablespoons canned tuna in water, drained and mashed
• 1 tablespoon finely chopped cucumber
• 1 tablespoon plain, unsweetened yogurt (optional, if your dog handles dairy well)
• A few small dog biscuits or kibble pieces (optional)

Instructions

1. Stand the KONG in a tall cup with the big hole facing up.
2. In a bowl, mix the sweet potato, tuna, cucumber, and yogurt.
3. Drop a few kibble pieces in the bottom of the KONG. This helps seal the small hole.
4. Spoon in the mix a little at a time. Press it down firmly with the back of a spoon.
5. Fill all the way to the top and smooth it flat.
6. Freeze for at least 4 hours.
7. Hand it to your dog on a washable mat or outdoors.

Notes

• Make 3 or 4 at once and keep them in the freezer for busy mornings.
• A first-time KONG dog may need an easier version. Skip the freezing for the first try.
• Count the stuffing as part of your dog’s daily food, not as an extra.

Pro tip: Layer the filling. Put a little kibble, then tuna mash, then more kibble, then mash again. Your dog has to work harder, and the toy lasts longer.

5. Dehydrated Tuna Sweet Potato Dog Treat Jerky

If your dog loves chewy snacks, this recipe is for you. You spread the tuna and sweet potato mix into a thin sheet, cut it into strips, and dry it slowly. The result is chewy, bendy “jerky” that is easy to snap into pieces.

A dehydrator gives the best results. No dehydrator? Your oven on its lowest setting works too, just with a little more babysitting.

Best for: Chewy lovers, travel bags, and long walks.

Recipe Card:

Prep Time: 20 minutes
Dry Time: 6 to 8 hours in a dehydrator (or 2 to 3 hours in an oven)
Freeze Time: Not needed
Yield: About 30 strips

Ingredients

• 1 cup cooked, mashed sweet potato
• 1 can (5 oz) tuna packed in water, very well drained
• 1 tablespoon oat flour (helps hold the strips together)

Instructions

1. Squeeze the tuna in a paper towel to remove as much water as you can.
2. Mix the tuna, sweet potato, and oat flour until it forms a smooth paste.
3. Line a dehydrator tray or baking sheet with parchment paper.
4. Spread the paste in a thin, even layer, about ⅛ inch thick.
5. Use a knife or pizza cutter to score the paste into thin strips.
6. Dehydrator: dry at 160°F (71°C) for 6 to 8 hours. Oven: set it to the lowest setting, prop the door open slightly, and dry for 2 to 3 hours.
7. Flip the sheet halfway through and separate the strips.
8. The jerky is done when it feels dry, firm, and bends without feeling wet inside.
9. Cool completely before storing.

Notes

• Thinner strips dry faster and turn out crispier. Thicker strips stay chewy.
• Cut the strips into smaller pieces for little dogs.
• Because this recipe contains fish, store it in the fridge or freezer.

Pro tip: Keep the paste thin and even. Thick spots dry slowly and can stay damp inside, which means they spoil faster.

6. Soft Tuna Sweet Potato Training Treats

Training takes dozens of rewards in a single session. So the best training treat is small, soft, smelly, and quick to swallow. That is exactly what these squares are.

You bake one flat sheet, then cut it into pea-sized cubes. One batch makes hundreds. Your dog stays focused, and you do not fill them up on calories.

Best for: Puppy classes, recall practice, and tricks. Reward-based methods work especially well, as explained in this guide to positive reinforcement training.

Recipe Card:

Prep Time: 15 minutes
Bake Time: 20 minutes
Freeze Time: Optional, for storage
Yield: About 200 pea-sized pieces

Ingredients

• 1 cup cooked, mashed sweet potato
• 1 can (5 oz) tuna packed in water, drained
• 1 large egg
• 1 cup oat flour
• ¼ cup water

Instructions

1. Heat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
2. Mix the sweet potato, tuna, and egg in a bowl.
3. Stir in the oat flour and water until you get a thick, spreadable batter.
4. Spread the batter in the pan, about ¼ inch thick. Wet your spatula to smooth it.
5. Bake for 15 to 18 minutes, until the top is set and no longer shiny.
6. Let it cool for 10 minutes. Lift out the sheet using the parchment.
7. Cut it into tiny squares, about ¼ inch each.
8. For firmer pieces, spread them on the pan and bake 5 more minutes.

Notes

• Cut the squares smaller for tiny breeds.
• Freeze half the batch right away to keep it fresh.
• Keep a handful in a treat pouch for walks.

Pro tip: Use a pizza cutter to slice the sheet into rows, then turn and cut again. It is much faster than a knife.

7. Three Easy Ingredient Variations

Once you have the basic mix down, you can adjust it. These swaps work best with Recipes 1, 2, and 6.

A. Egg-Free Version

Some dogs react to eggs, and some owners are out of them. Swap each egg for 2 tablespoons of plain, unsweetened yogurt or 2 tablespoons of extra sweet potato mash. The treats turn out slightly softer. Add a tablespoon of oat flour if the dough feels loose.

B. Pumpkin Boost Version

Replace half the sweet potato with plain pumpkin puree. Check the can first: it must say “100% pumpkin,” not “pumpkin pie filling.” Pie filling has sugar and spices that do not belong in dog treats. Pumpkin makes the treats lighter and gives them a golden color.

C. Parsley and Blueberry Version

Stir in 1 tablespoon of chopped fresh parsley and ¼ cup of mashed blueberries. Parsley adds a fresh smell, and blueberries add a bit of natural sweetness. The treats come out speckled and a little purple, which looks cute in a gift jar.

8. Storage, Serving Size and Safety

Good treats are only good if they are safe. Keep these rules in mind every time you cook.

How to store them

• Baked biscuits (Recipe 1): airtight container for 3 to 4 days on the counter, 1 week in the fridge, or 2 months in the freezer.
• Muffin bites and training squares (Recipes 2 and 6): fridge for up to 5 days, freezer for 2 months.
• Pupsicles and KONGs (Recipes 3 and 4): freezer for up to 2 months.
• Jerky (Recipe 5): fridge for up to 1 week, freezer for up to 2 months.
• Dried, hard biscuits keep longer than soft ones, but fresh fish is always the first to spoil. When in doubt, throw it out.

If you also bake hard treats like dog bone treats, keep them in a separate jar so the soft and crunchy ones do not mix.

How much to serve

• Treats should make up no more than about 10% of your dog’s daily calories.
• Tiny dogs (under 10 lb): about 1 biscuit or a few training squares a day.
• Medium dogs (20 to 50 lb): 2 to 3 biscuits a day.
• Large dogs (over 50 lb): 3 to 4 biscuits a day.
• Count KONG stuffing and training squares toward the same limit.

Ingredient safety

• Always use tuna packed in water with no salt, oil, or seasoning.
• Never add onion, garlic, chives, xylitol, chocolate, or raisins.
• Cook the sweet potato until soft. Raw sweet potato is hard to chew and hard to digest.
• Peel the potato for small dogs and puppies. The skin can be tough.
• Watch dogs eating frozen treats, and cut up large pieces for small mouths.

9. Quick Health Notes

Why tuna and sweet potato work well together? Here is the short version.

Tuna is a lean source of protein and omega-3 fats. These fats can support skin and coat health. Sweet potato adds fiber for digestion, plus vitamins and minerals like vitamin A and potassium. Together, they make a treat that is simple and made from whole foods.

There is one thing to remember. Tuna can contain mercury, so treat it as an occasional snack, not a daily food. Light or skipjack tuna is usually a smarter pick than albacore. Small dogs, puppies, and dogs with health problems need extra care.

Every dog is different. If your dog has allergies, kidney problems, or a sensitive stomach, ask your vet before adding new foods. A good starting place for new owners is this guide to puppy veterinary needs.

Final Words

Tuna sweet potato dog treats are cheap, fast, and flexible. You can bake them, freeze them, stuff them, dry them, or cut them into tiny training bites. One simple mix gives you six different ways to say “good dog.”

Start with the soft baked biscuits if you want the easy win. Try the pupsicles when the weather gets hot. Keep a bag of training squares in your pocket for walks and lessons. Whichever recipe you pick, check the labels, keep portions small, and let your dog’s reaction guide you.
