The smell hooked me first. Warm tuna mixed with sweet potato hits the kitchen like comfort food, not dog food. I remember thinking, wow, this actually smells better than half my own snacks.
I made these on a random afternoon when my dog stared at me like I owed him rent. I wanted something soft, simple, and not full of mystery ingredients. That moment turned into one of my favorite go-to dog treat recipes.

What Makes This Recipe Shine
I’m just going to say it: store-bought dog treats feel sketchy sometimes. I read labels, squint at words I can’t pronounce, and still feel unsure. This recipe skips all that nonsense and keeps things refreshingly honest.
These treats stay soft without weird fillers or tricks. The sweet potato does the heavy lifting, and the tuna brings serious flavor without trying too hard. Dogs don’t need gourmet drama, and this recipe respects that.
I love how forgiving this recipe feels. You don’t need perfect measurements or fancy tools to pull it off. If you mash, mix, and bake with a little care, you win.
The texture also matters more than people think. Crunchy treats feel trendy, but many dogs prefer soft bites, especially seniors or aggressive chewers. These treats bend instead of shatter, and that detail makes a big difference.
I also trust this recipe on busy days. I throw it together while cleaning the kitchen or waiting on laundry. The whole process feels low-stress, which honestly makes me want to make it again.
Ingredients You’ll Need
I keep the ingredient list short on purpose. Dogs don’t care about long ingredient lists, and neither do I. Simplicity always wins in my kitchen.
Here’s what you need to grab before you start mixing. You probably already have most of this waiting around. If not, one quick store run fixes everything.
- Canned tuna in water – Skip oil-packed tuna unless you enjoy greasy fingers and judgmental looks.
- Cooked sweet potato – Soft, mashable, and naturally sweet without trying too hard.
- Egg – This holds everything together like a responsible adult.
- Oat flour or rolled oats – This adds structure without making things crunchy.
- Optional parsley – This helps with breath, not miracles, but every little bit helps.
I always choose tuna packed in water because it keeps things lighter. Oil-heavy tuna can upset sensitive stomachs, and I don’t like rolling those dice. I drain it well so the dough stays manageable.
Sweet potato needs to feel fork-soft before mixing. I bake or microwave it until the inside turns fluffy and cooperative. Hard chunks ruin the vibe and the texture.
Oats give you flexibility here. You can blend rolled oats into flour or use oat flour straight from the bag. I switch between both depending on how lazy I feel.
Step-by-Step Instructions
Step 1: Prep the Sweet Potato
Start by cooking your sweet potato until it feels soft all the way through. I usually poke holes in it and microwave it because life feels busy enough already. Let it cool slightly so your fingers don’t regret your choices.
Peel the skin off once it cools. Mash the inside until it looks smooth and lump-free. Aim for a texture like thick mashed potatoes.
Step 2: Drain and Flake the Tuna
Open the tuna and drain every drop of water you can. Excess moisture turns the dough sticky and annoying. Flake the tuna with a fork until it breaks down evenly.
I check for large chunks because dogs notice texture more than we think. Smaller flakes mix better and spread flavor evenly. This step takes less than a minute, so don’t rush it.
Step 3: Mix the Base Ingredients
Add the mashed sweet potato and flaked tuna to a mixing bowl. Crack the egg right on top and stir everything together. The mixture should start looking cohesive and slightly sticky.
If the mix looks too wet, add oat flour one spoon at a time. Stir after each addition so you don’t overshoot. You want a dough that holds shape without clinging to everything.
Step 4: Adjust the Dough Texture
Sprinkle in parsley if you use it. Stir gently so the herbs distribute evenly. Give the dough a quick squeeze test with your fingers.
The dough should feel soft but not wet. If it sticks aggressively, add more oats. If it crumbles, add a spoon of mashed sweet potato.
Step 5: Shape the Treats
Line a baking tray with parchment paper. Scoop small portions of dough and roll them into balls. Flatten them slightly with your fingers.
I keep them bite-sized because dogs get excited fast. Smaller treats also bake more evenly. Uniform shapes help everything cook at the same pace.
Step 6: Bake Until Soft and Set
Preheat your oven and slide the tray inside. Bake until the treats set on the outside but stay soft inside. The surface should feel dry, not crunchy.
Let the treats cool completely before serving. Cooling helps them firm up just enough. Your dog will probably hover during this step.
Common Mistakes to Avoid
People often skip draining the tuna properly. That extra moisture ruins the dough and leads to frustration. Take thirty extra seconds and save yourself the headache.
Overbaking also sneaks up on people. These treats don’t need to turn golden brown to finish. Pull them early if you want that soft texture.
Some folks add too much flour too fast. Slow additions matter here. You can always add more, but fixing dry dough feels annoying.
Alternatives & Substitutions
You can swap tuna for cooked salmon if you want variety. I do this when tuna prices feel rude. Salmon brings richer flavor, so dogs usually love it.
Sweet potato alternatives exist too. Pumpkin puree works well and keeps the texture soft. I avoid canned versions with added sugar because that feels unnecessary.
If oats don’t work for your dog, rice flour steps in nicely. The texture stays soft, and digestion stays smooth. IMO, flexibility makes this recipe a keeper.
FAQ (Frequently Asked Questions)
Can puppies eat these soft treats?
Yes, puppies can enjoy these treats in small amounts. The soft texture helps tiny teeth handle them easily. I always break them into smaller pieces for training sessions.
How long do these treats last?
These treats last about five days in the fridge. I store them in an airtight container to keep them fresh. You can freeze them if you want longer storage.
Do these treats smell strong?
They smell like tuna, so yes, a little. The scent fades after baking and cooling. Dogs still notice everything, though.
Can I skip the egg?
You can skip the egg if needed. Add extra sweet potato to help bind the dough. The texture stays softer but still workable.
How many treats can I give per day?
Moderation matters here. I treat these like snacks, not meals. A few per day works well for most dogs.
Can I use fresh tuna instead?
Fresh tuna works if you cook it fully first. I usually stick with canned because it saves time. Both options deliver solid flavor.
Final Thoughts
I keep coming back to this recipe because it feels honest and easy. The ingredients make sense, and the process never stresses me out. My dog reacts like I just invented something magical.
If you want a soft, simple treat that actually smells good, this one deserves a try. You don’t need perfection here, just a little care. FYI, your dog will remember this favor.
