Step 4: Cool and Store
- Let the treats cool completely before serving.
- Store in an airtight container in the fridge for up to a week, or freeze for up to three months.
Why Tuna is a Superfood for Dogs
Tuna is far more than a tasty snack—it’s brimming with nutrients that benefit your dog from head to tail.
1. Omega-3 Fatty Acids
Tuna is an excellent source of omega-3s, which:
- Promote a shiny, soft coat.
- Soothe inflammation and reduce joint pain.
- Support heart health and brain function.
2. High-Quality Protein
Tuna is a lean protein.
It builds strong muscles and repairs tissues.
It’s ideal for active or aging dogs.

3. Packed with Essential Nutrients
Tuna contains key vitamins and minerals, like:
- Vitamin B12: Boosts energy and supports red blood cell production.
- Selenium: A natural antioxidant that protects cells and promotes a healthy immune system.
- Potassium: Helps maintain healthy nerves and muscle function.
Quick Tip: Rotate tuna treats with other protein snacks, like chicken or beef.
This will avoid too much mercury exposure.
How to Choose the Best Tuna for Your Dog

Not all tuna is safe for dogs.
Use these tips to choose the best option:
- Tuna in Water: Always opt for tuna packed in water, not oil, to avoid unnecessary fats.
- No Added Salt or Seasonings: Use low-sodium or unsalted tuna. It helps prevent too much salt intake.
- Stick to Light Tuna: Light tuna, like skipjack, has less mercury than albacore or yellowfin.
- BPA-Free Cans: Choose BPA-free cans to reduce exposure to harmful chemicals.
How to Introduce Tuna Treats to Your Dog
Tuna treats are tasty and nutritious.
If your dog hasn’t had tuna before, introduce it slowly.
New foods can upset sensitive stomachs.
A gradual approach ensures your pup enjoys the treats without any issues.
Start Small
- Begin with a small piece of the treat to see how your dog reacts.
- For small dogs, offer a piece about the size of a pea; for large dogs, a dime-sized portion is a good starting point.

Monitor for Reactions
- Watch your dog closely after their first taste. Look for signs of digestive upset, such as diarrhea or vomiting.
- If there are no issues, you can gradually increase the portion size over the next few days.
Mix with Familiar Foods
- If your dog seems hesitant about the strong smell or taste of tuna, try crumbling the treat over their regular food.
- Mixing it with something familiar can help them adjust to the new flavor.
Avoid Overfeeding
- While tuna is healthy, too much can lead to mercury exposure. Stick to the recommended portion sizes based on your dog’s size and weight.
Gradually introduce tuna treats.
This way, your dog gets all the benefits without any tummy troubles.
Once they get used to the taste, they’ll be hooked!
