Krill Oil for Dogs

Reviewed by Dr. Angela Beal, DVM

Krill oil for dogs is a source of omega-3 fatty acids and naturally occurring antioxidants derived from small marine crustaceans. Like fish oil, it’s often used to support skin health, coat condition, and joint comfort, but krill oil is known for delivering omega-3s in a form that some dogs may absorb more easily. It also contains astaxanthin, an antioxidant that may help support overall cellular health.

At Chewy, you can find krill oil in both liquid supplements and soft chew formulas, often combined with other ingredients for skin, coat, or joint support. Some products use krill oil alongside fish oil or additional omegas, while others focus on broader wellness blends that support multiple areas at once. These formulations make it easy to add krill oil into your dog’s routine, whether mixed into meals or given as a daily chew. Here are some things to consider when choosing krill oil for your pup:

• Omega-3 support: Provides EPA and DHA to help support skin, joints, and overall wellness
• Antioxidant content: Naturally contains astaxanthin, which supports cellular health
• Absorption benefits: Omega-3s in krill oil are bound to phospholipids, which may aid absorption
• Combination formulas: Often included in blends for skin, coat, or joint support
• Easy administration: Available as liquids or chews for flexible daily use

Krill oil for dogs can be a helpful alternative or complement to traditional fish oil, especially for dogs needing omega-3 support for skin, coat, or mobility. As with any supplement, it’s best to follow serving guidelines and consult your veterinarian if your dog has specific health needs or sensitivities.
