Fish Oil for Dogs: Ask Your Vet First

A healthy dog on a complete and balanced food already gets the fats it needs. If you're thinking about adding fish oil, for the coat, the joints or anything else, ask your vet first: they can check your dog, say whether it would help, and tell you how much is right. For a shiny coat day to day, regular brushing and a good diet do most of the work.

Supplements, including fish oil: see your vet or a pet supply store with trained staff. They can tell you whether your dog needs one and how much is safe.

Why It's a Vet Question

Fish oil is sold for many reasons, and products vary a lot in strength. More isn't better: too much fat can upset a dog's stomach and add calories, and some dogs have health conditions or take medicines where it matters. A dull coat or itchy skin can also have causes that a supplement won't fix, such as parasites, skin problems or diet.

So the order is: vet first, then supplement if your vet suggests one, at the amount they suggest.

A look-over each week for dry patches, lumps or sore spots to mention to your vet.
