A dog's coat is one of the few health signals an owner can actually see, which is why a dull or flaky one gets noticed long before whatever is causing it does. An oil supplement is one of the more direct ways to address it, since it goes straight into the diet rather than onto the coat.

This is a 500ML bottle of a 100% vegetable oil blend, made from linseed oil and hemp oil rather than fish oil. Despite the "Omega 3" name, GWF describe it as fish free, as well as wheat gluten free, non-GM and soya free. It's a genuinely concentrated oil: crude fat runs to 96.5%, supplying 47% omega-3 fatty acids and 26% omega-6. GWF deliver it through what they call the Oatinol system, intended to help with absorption.

What the label actually says: this is a plant-oil source, not a fish oil, so if you specifically want a marine-derived omega-3 for your dog or cat, this isn't it. No dosing amount is given on the information supplied to us, so go by the bottle's own instructions or ask your vet how much to add to a bowl.

Who it's for: owners of a dog or cat with a dull coat, dry skin or heavy moulting who want a plant-based oil rather than a fish one, including households avoiding fish for allergy reasons.
