Dog skin supplements for Dachshund & Jack Russell

Two dogs, two opposite coat problems — a flaky Dachshund and an oily Jack Russell — is actually more common than it sounds, and it's worth separating them rather than assuming they need the same fix. Skin and coat issues in dogs usually fall into two categories: dietary deficiency or an underlying skin condition. Supplements genuinely help with the first, but they won't touch the second. So before I point you toward anything, it helps to understand both dogs a bit better. How old are they, what are you feeding them day to day, and how long have you been seeing these symptoms in each?

That's useful — no itching rules out a lot of the more complicated stuff like allergies or mange. The fact that they're both on the same mid-range kibble and showing coat issues is a strong signal. Supermarket own-brand dry food often has lower omega-3 fatty acid levels than the label implies, especially if it's been stored a while. Omega-3 deficiency can actually show up as dry, flaky skin in some dogs and as overactive sebaceous glands — which causes oiliness — in others. The coat problem looks different on the outside but can have the same root cause. Can I ask: is the Dachshund's flakiness all over, or concentrated around the back and base of the tail? And with the Jack Russell, is the greasiness along the back mostly, with any smell to the coat?

It's a very common assumption with Jack Russells but it's not inevitable — that pattern, greasy back with a mild odour, is classic seborrhoea oleosa, which in an otherwise healthy, non-itchy dog is usually a fatty acid imbalance rather than a skin disease. And your Dachshund's distribution sounds like straightforward dry skin from the same dietary gap. Both patterns point to the same correction: boosting omega-3 and omega-6 in the right ratio. I'd recommend YuMEGA Dog by Lintbells. It's a cold-pressed oil blend — salmon oil, starflower oil, and vitamin E — specifically formulated for dogs showing either dry or oily coat issues. It's one of the better-evidenced products in this space and it works as a daily food topper. One bottle covers both dogs. I'd give it six weeks consistently before judging whether it's working.

No — dose by weight. The YuMEGA bottle has a clear dosing guide on the back based on the dog's body weight, so your Dachshund and Jack Russell will likely get different amounts. A standard adult Dachshund is usually around 8–10kg, and a Jack Russell around 6–8kg, so they'll be fairly close but not identical. Just measure separately rather than doing a rough pour for both. One practical tip: start at half the recommended dose for the first week if either dog has a sensitive stomach — fish oils can occasionally cause loose stools when introduced too quickly.

Two things worth doing in parallel. First, look at upgrading the kibble — not necessarily to anything expensive, but choosing a food where a named fish or meat is the first ingredient and that lists omega-3 content on the label. The supplement can correct a deficiency, but a better baseline diet means you may not need to stay on the supplement long-term. Second, for the Jack Russell specifically, a weekly brush-through with a rubber grooming mitt will help distribute the sebum more evenly and reduce the build-up that causes the smell. If after six weeks on YuMEGA the oiliness hasn't improved, it's worth a vet visit just to rule out primary seborrhoea, but I'd be surprised — the dietary cause fits well here.
