Why this matters

In our evaluation, we found that omega-3 concentration and freshness matter more than the fish source alone. Many products with pollock and salmon blends offer excellent value without sacrificing quality.

The Options

Types Explained

Wild Alaskan Salmon Oil

Pure oil from wild-caught salmon, often with no additives. High in omega-3 but may vary in concentration.

Best for: Dogs needing a simple, natural supplement

Blended Fish Oil

Combines salmon with other fish like pollock for a broader omega profile. Often more affordable.

Best for: Budget-conscious owners and dogs that tolerate mixed oils

Salmon Oil with Added Antioxidants

Includes vitamin E or rosemary extract to preserve freshness. Offers extra skin benefits.

Key Buying Factors

Omega-3 Content

Look for EPA and DHA levels per serving. Higher concentrations mean fewer pumps or teaspoons needed.

Source & Purity

Wild Alaskan salmon is preferred for lower contaminant risk. Third-party testing for heavy metals and PCBs adds confidence.

Freshness & Stability

Salmon oil oxidizes quickly. Dark bottles and added vitamin E (as preservative) help maintain quality.

Palatability

A strong fishy smell may deter picky dogs. Many oils add natural flavorings to improve taste.

Ease of Dosing

Pump bottles allow precise dosing. Some products come with a marked syringe.

Value per Serving

Compare cost per mg of combined EPA and DHA, not just bottle size.

Living With It

Care, Cost and Maintenance

Storage

Store salmon oil in a cool, dark place. Refrigerate after opening to slow oxidation.

Dosage

Start with the lowest recommended dose and increase gradually. Adjust based on dog's weight and response.

Shelf Life

Use within 60-90 days after opening. Discard if oil smells rancid or changes color.

Pro tip

To maximize freshness, we recommend buying smaller bottles that will be used within a month, and always check the packaging date. A dark glass bottle is a good sign the brand cares about stability.

Frequently asked questions

How much salmon oil should I give my dog?

The typical dose is 1 teaspoon per 10-20 lbs of body weight daily. Check the product label for specific recommendations.

Can salmon oil cause diarrhea?

Starting with too high a dose can cause loose stools. Gradually introduce the oil and split the daily amount between meals.

Is salmon oil safe for dogs with allergies?

Salmon oil is generally safe, but if your dog is allergic to fish, avoid it. Always consult your vet before adding supplements.

How long does salmon oil last?

Unopened bottles last 1-2 years if stored properly. Once opened, use within 60-90 days and refrigerate to extend shelf life.

What is the difference between salmon oil and fish oil?

Salmon oil is a specific source of fish oil, often higher in omega-3s than generic fish oil blends. Salmon oil also has a distinct flavor.
