Dull coat, dry flaky skin, or itchiness? Here's how omega-3 supplements help — and how to choose one that works.
What omega-3 does
Omega-3 fatty acids — mainly EPA and DHA from fish oil — reduce inflammation and strengthen the skin barrier, which shows up as a shinier coat and less itching over time. A concentrated liquid like [Nutramax Welactin Omega-3 for Dogs](/products/nutramax-welactin-omega-3-for-dogs) pumps onto food and delivers a meaningful dose, making it one of the most evidence-backed supplements you can add for skin and coat.

Liquid vs. chews
Liquids let you scale the dose precisely to your dog's weight and tend to pack more EPA and DHA per serving. Soft chews like [Zesty Paws Omega Bites Salmon Chews](/products/zesty-paws-omega-bites-salmon-chews) trade some potency for the convenience of a treat your dog looks forward to. Pick whichever you'll give consistently — with omega-3, daily habit beats a stronger product you skip.
Beyond skin: joints and more
Omega-3s do double duty, easing the inflammation behind stiff joints too, which is why they pair so naturally with a joint chew like [Nutramax Cosequin Maximum Strength Joint Chewables](/products/nutramax-cosequin-maximum-strength-joint-chewables) for older dogs. They also support heart and cognitive health. Look for a stated EPA and DHA amount rather than just total fish oil, and store liquids cool and sealed so the oil doesn't go rancid and quietly lose its benefit before you finish the bottle.
Give it time, and loop in your vet
Coat and skin improvements are gradual — expect several weeks to a couple of months of daily dosing before you see the full shine. These supplements support skin health and complement, rather than replace, veterinary care. If your dog's itching, flaking, or hair loss is severe or worsening, see your vet, since allergies and infections need proper diagnosis and treatment.
