Your dog’s coat should be gleaming, not looking like it’s been through a static storm.

I used to think a good brushing and the occasional coconut oil rub were enough—until my pup’s fur started losing its shine, and the itching became a daily drama. Cue the frantic ingredient label reading, the overthinking, the desperate attempts at DIY remedies (note: olive oil baths? Not my best idea).

Turns out, the real MVP? Omega-3s. They work from the inside out, supporting everything from skin health to joint mobility. And the best part? You don’t need to rely on pricey supplements or mystery-ingredient dog food.

Just a few simple, tasty treats packed with the good stuff.

Let’s get those tails wagging and that coat shining!

As a pet parent, I’ve always been on the lookout for healthy, homemade treats that not only make my dog’s tail wag but also support their overall well-being.

Whether you’re looking to boost your dog’s skin and coat health, support their joints, or simply reward them with something delicious, these treats are a game-changer.

They’re incredibly easy to make, even if you’re not a seasoned baker.

Why You’ll Love This Recipe

  • Cost-Effective: At just 5−5−7 per batch, these treats are far more affordable than store-bought omega-3 supplements or premium dog treats.
  • Ingredient Control: You know exactly what’s in these treats—no hidden preservatives or questionable additives.
  • Storage Convenience: These treats stay fresh for weeks and can be frozen for up to three months, making them perfect for batch preparation.
  • Training Effectiveness: Their small size and irresistible flavor make them ideal for training sessions.
  • Portion Control: With clear serving guidelines, you can easily manage your dog’s calorie intake.

Essential Information

Prep Time: 15 minutes
Cook Time: 25-30 minutes
Total Time: 40-45 minutes
Yield: 24-30 small treats (1-inch size)
Shelf Life: 2 weeks at room temperature, 1 month refrigerated, or 3 months frozen
Storage Requirements: Store in an airtight container to maintain freshness.

Equipment Needed

To make these treats, you’ll need a mixing bowl, a baking sheet, parchment paper or a silicone baking mat, and cookie cutters (1-inch size works best). If you don’t have cookie cutters, you can simply slice the dough into small squares. A rolling pin is optional but helpful for achieving an even thickness. Don’t forget an airtight container for storage!

Ingredients (Main Components)

Ingredients (Main Components)
  • 1 cup (120g) cooked salmon: Flaked and free of bones and skin. Salmon is rich in omega-3s, which support skin, coat, and joint health.
  • 1/4 cup (30g) ground flaxseed: A great source of fiber and additional omega-3s. Make sure it’s ground for better digestion.
  • 1 cup (120g) oat flour: You can substitute almond flour for a grain-free option.
  • 1 large egg: Binds the ingredients together and adds protein.
  • 1/4 cup (60ml) water: Adjust as needed to achieve the right dough consistency.

Safety Note: Always use fully cooked salmon to eliminate the risk of salmonella. Avoid any seasoning or additives that could harm your dog.

Expert Tips (Before Instructions)

  1. Cook the Salmon Thoroughly: Raw salmon can carry bacteria, so always bake or boil it before use.
  2. Grind the Flaxseed: Whole flaxseed can pass through your dog’s system undigested, so grinding it ensures they get all the nutritional benefits.
  3. Adjust Dough Consistency: If the dough feels too dry, add a little more water. If it’s too sticky, sprinkle in some extra flour.
  4. Monitor Baking Time: Overbaking can make the treats too hard, so keep an eye on them during the last few minutes.
  5. Cool Completely: Let the treats cool fully before storing to prevent moisture buildup.

Instructions

Instructions
  1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. In a mixing bowl, combine the flaked salmon, ground flaxseed, oat flour, and egg. Mix until well combined.
  3. Gradually add water, mixing until a dough forms. The dough should hold together without being too sticky.
  4. Roll the dough out to about 1/4-inch thickness on a lightly floured surface.
  5. Use cookie cutters to cut the dough into small, bite-sized pieces. If you don’t have cutters, slice the dough into squares.
  6. Place the treats on the prepared baking sheet, leaving a little space between each one.
  7. Bake for 25-30 minutes, or until the treats are golden brown and crispy.
  8. Allow the treats to cool completely before serving or storing.

Variations and Substitutions

  • Dietary Adaptations: For grain-free options, use almond flour instead of oat flour.
  • Protein Alternatives: Substitute salmon with canned sardines (in water, no salt added) for a different omega-3 boost.
  • Flavor Enhancers: Add 1 tsp dried parsley or 1/4 tsp turmeric for extra flavor and anti-inflammatory benefits.
  • Puppy-Friendly Version: Skip the salmon and use cooked chicken instead, as puppies are more sensitive to fish.

Pro Tips and Success Secrets

  • Batch Preparation: Double or triple the recipe and freeze the extras for future use.
  • Storage Optimization: Store treats in small portions to avoid frequent thawing and refreezing.
  • Breaking for Small Dogs: If you have a small breed, break the treats into smaller pieces to prevent choking.
  • Training Use: These treats are perfect for training sessions due to their small size and high palatability.

Serving Guidelines

  • Small Dogs (under 20 lbs): 1 treat per day
  • Medium Dogs (20-50 lbs): 2-3 treats per day
  • Large Dogs (50+ lbs): 3-4 treats per day

These treats are great for training, as occasional snacks, or even as part of a special occasion celebration.

Common Questions

Can I use raw salmon?
No, always cook salmon thoroughly to eliminate the risk of salmonella.

How long do these treats last?
They stay fresh for 2 weeks at room temperature, 1 month in the fridge, or 3 months in the freezer.

Can I substitute flaxseed?
Yes, chia seeds are a great alternative for additional omega-3s.

Are these treats suitable for puppies?
Not recommended for puppies due to the potential salmonella risk in fish.

Homemade Sardine & Sweet Potato Dog Treats – A Powerful Omega-3 Boost for Your Pup

If you’ve ever watched your dog struggle with itchy skin, dull fur, or stiff joints, you know how heartbreaking it can be. My dog, Max, used to scratch constantly, and despite switching to premium food, his coat remained lackluster. After doing some research, I realized he needed more omega-3 fatty acids in his diet to combat inflammation and support healthy skin and joints.

These treats are soft and chewy, making them perfect for all dog sizes, including puppies and senior dogs who may struggle with harder treats. They’re easy to digest and free from artificial preservatives, making them ideal for dogs with allergies or food sensitivities.

Expert Tips Before You Start

  1. Use plain, unsalted sardines. Avoid sardines packed in oil, salt, or seasonings, as these can be harmful to dogs.

  3. Adjust the texture based on your dog’s needs. Add a little water if the dough is too dry for rolling.
  4. For extra crunch, bake longer. If your dog prefers a crunchier treat, bake for an additional 5 minutes.
  5. Let treats cool completely before storing. This prevents condensation and keeps them fresh longer.

Ingredients (Main Components)

Ingredients (Main Components)
  • 1 cup oat flour (or finely blended oats) – provides fiber for digestion and a hearty texture
  • ½ cup natural peanut butter (unsalted, xylitol-free) – adds protein and a nutty flavor dogs love
  • ¼ cup ground flaxseeds – an excellent source of omega-3s for skin and coat health
  • 1 egg – helps bind ingredients together and adds extra protein
  • ¼ cup unsweetened applesauce – a natural sweetener with added vitamins

Storage Tip: Store peanut butter in the fridge after opening to keep it fresh longer. Always check that your peanut butter does not contain xylitol, which is toxic to dogs.

Expert Tips Before You Start

  1. Use high-quality peanut butter. Ensure it’s free from xylitol, artificial sweeteners, and added sugar.
  2. Grind the flaxseeds for better absorption. Whole flaxseeds may pass through your dog’s system undigested.
  3. If the dough is too sticky, refrigerate it for 10 minutes. This makes it easier to roll out and cut.
  4. For softer treats, bake for a shorter time. Reduce baking time to 15 minutes for a chewier texture.
  5. Let the treats cool completely before storage. This prevents moisture buildup and helps maintain crispness.
