As a holistic veterinarian, I’m often asked which supplements make the biggest difference for a dog’s long-term health. One of my top recommendations is Tuna Omega-3 Oil by Standard Process. This supplement is rich in essential fatty acids that support skin, joints, the immune system, and overall vitality.
Let’s take a closer look at why I trust this formula, how it works, and how you can use it safely at home.

What is Tuna Omega-3 Oil by Standard Process?
Tuna Omega-3 Oil is a high-quality fish oil made from deep-ocean tuna. It’s packed with two essential fatty acids:
- EPA (Eicosapentaenoic Acid): helps manage inflammation and supports joint and heart health.
- DHA (Docosahexaenoic Acid): supports brain, eye, and nervous system function.
Although this supplement was originally formulated for people, it’s also safe and effective for dogs when given in the right amount. Standard Process has produced whole-food-based supplements since 1929, and their quality control is among the best in the industry.
A Little History
People have used fish oil for centuries. Coastal cultures, such as the Vikings and Inuits, noticed that eating oily fish improved stamina, skin, and heart health. Modern science now confirms what they observed: Omega-3 fats reduce inflammation, strengthen the immune system, and help regulate metabolism.
Veterinarians have used Omega-3 supplements for decades to manage conditions like allergies, arthritis, and heart disease. I’ve personally seen impressive results in dogs of all ages—from young pets with itchy skin to older dogs struggling with stiffness or dull coats.
Key Benefits for Dogs
Tuna Omega-3 Oil can support many areas of canine health:
- Skin and Coat: Reduces dryness, itchiness, and excessive shedding. Promotes a shiny, soft coat.
- Joints and Mobility: Eases stiffness from arthritis or age-related inflammation.
- Heart Health: Helps regulate cholesterol and blood pressure, supporting healthy circulation.
- Brain Function: Aids cognitive performance in older dogs and supports learning in puppies.
- Immune Balance: Reduces chronic inflammation that can weaken immunity.
Omega-3s are essential fats, meaning dogs can’t produce them naturally. They must come from the diet or supplements. Adding Tuna Omega-3 Oil is an easy way to fill that nutritional gap.

What’s Inside: Ingredient Breakdown
Each softgel contains a clean, concentrated blend of nutrients that work together for whole-body support:
- Tuna Oil: Primary source of Omega-3s for anti-inflammatory and cellular health benefits.
- EPA: Reduces inflammation, eases joint discomfort, and supports heart function.
- DHA: Supports brain development, eye health, and cognitive function in all life stages.
- Vitamin E (d-alpha tocopherol): A natural antioxidant that protects cells and keeps the oil fresh.
This simple but powerful formula provides targeted nutritional support without unnecessary fillers.
How It Helps With Specific Health Concerns
You can use Tuna Omega-3 Oil to help manage or prevent several common issues:
Joint Problems:
- Reduces pain and inflammation from arthritis.
- Supports cartilage and connective tissue repair.
Heart and Circulation:
- Helps lower triglycerides and blood pressure.
- Promotes strong cardiovascular function.
Skin Allergies and Coat Health:
- Soothes itchy, flaky skin.
- Reduces hot spots and promotes healing.
Cognitive Function:
- Supports brain health and alertness in senior dogs.
- Improves focus and learning in puppies.
Immune Health:
- Modulates inflammation, helping the body respond appropriately to illness or injury.
Some of my holistic care plans also include cold laser therapy for dogs with chronic inflammation or joint pain. Combining laser therapy with Omega-3 support can amplify healing and reduce discomfort faster.

How to Give Tuna Omega-3 Oil to Your Dog
The right dose depends on your dog’s size and overall health. Here’s a general guideline I use in my practice:
| Dog Size | Weight Range | Suggested Amount |
|---|---|---|
| Small | 1–20 lbs | ½ softgel twice daily |
| Medium | 21–50 lbs | 1 softgel twice daily |
| Large | 51+ lbs | 1½ softgels twice daily |
You can:
- Pierce the capsule and drizzle the oil over food.
- Mix directly into meals for easy feeding.
Most dogs love the taste. If yours is sensitive, start with a small amount and increase gradually.
Always consult your vet before starting any new supplement, especially if your dog has medical conditions or takes prescription medication.
Possible Side Effects and Safety Tips
Tuna Omega-3 Oil is very safe when given at the proper dose. However, a few dogs may experience:
- Loose stool or mild stomach upset (usually from too high a dose)
- A fishy odor on the breath or coat
If that happens, reduce the amount or split the dose between meals.
To keep the oil fresh:
- Store it in a cool, dark place.
- Check the expiration date.
- Close the bottle tightly to prevent oxidation (rancidity).
Avoid cheap fish oil products that may contain mercury or other contaminants. Standard Process uses third-party testing to confirm purity and potency, which is why I trust their brand for my patients.
When to Expect Results
You may start to see improvements in your dog’s coat and energy within two to four weeks. Joint and skin changes often take a little longer. Consistency matters, so make Tuna Omega-3 Oil part of your pet’s daily routine.
If your dog has chronic issues such as arthritis, allergies, or cognitive decline, consider pairing this supplement with a personalized holistic nutrition consultation. I offer these online to help pet parents create balanced home diets, supplement plans, and natural therapies tailored to each pet’s needs.
