Before You Buy
Key Buying Factors
01
Omega-3 Content
Look for EPA and DHA levels per serving. Higher concentrations mean fewer pumps or teaspoons needed.
02
Source & Purity
Wild Alaskan salmon is preferred for lower contaminant risk. Third-party testing for heavy metals and PCBs adds confidence.
03
Freshness & Stability
Salmon oil oxidizes quickly. Dark bottles and added vitamin E (as preservative) help maintain quality.
04
Palatability
A strong fishy smell may deter picky dogs. Many oils add natural flavorings to improve taste.
05
Ease of Dosing
Pump bottles allow precise dosing. Some products come with a marked syringe.
06
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.
