Krill oil and fish oil are go-to omega-3 supplements for dogs, valued for supporting skin, coat, and joint health, and in our evaluation we found that source quality and dosing convenience separate the strong products. Krill oil delivers omega-3s with naturally occurring astaxanthin, while salmon and cod-based oils are widely used and often more economical. We compared five popular options on their omega-3 source, freshness handling, and whether a pump makes daily dosing genuinely easier. What we like is an oil that is clear about its source, ships with a practical pump for mess-free dosing, and addresses freshness, since fish oils can oxidize. We looked at krill-only formulas, blends, and salmon oils across the lineup. Omega-3 supplements support skin and joint comfort but are not a treatment for medical conditions. If your dog has a diagnosed joint or skin disease, or takes medication, we recommend confirming the supplement and dose with your veterinarian first.

Key Buying Factors
Omega-3 source
Krill, salmon, and cod each deliver omega-3s differently, with krill adding natural astaxanthin. We favored products that clearly identify their source.
Pump dosing convenience
A pump makes daily dosing cleaner and more consistent than pouring. In our evaluation we weighted easy, mess-free dispensing for everyday use.
Freshness and oxidation
Fish oils can go rancid, so packaging and antioxidant content matter. We preferred products that address freshness, such as krill oil's built-in astaxanthin.
Stated EPA and DHA
The active omega-3s are EPA and DHA. We give more trust to brands that publish these amounts so you can judge potency with your vet.
Sourcing transparency
Wild-caught and named-region sourcing signals quality. We noted which brands, like Grizzly and Wild Alaskan, are specific about origin.
Palatability
An oil only helps if your dog eats its food with it added, so aggregated acceptance feedback factored into our picks.
Care, Cost and Maintenance
Store to prevent rancidity
Keep fish and krill oils cool and tightly sealed, and follow refrigeration guidance after opening, since oxidized oil loses benefit and smells off.
Dose to your dog's weight
Follow weight-based directions and start conservatively, since too much oil can cause loose stool. Your vet can confirm the right amount.
Add to meals
Pump the oil onto food so your dog gets the full dose, and watch that mealtime acceptance stays consistent.
Smell the oil before each use. A clean, mild sea scent means it is fresh, while a sharp or sour smell signals oxidation and that it is time to replace the bottle.
