Dog supplements for older Spaniels with ear issues

Recurring ear infections in an older Cocker Spaniel are really common — those long, floppy ears create a warm, moist environment that yeast and bacteria love — but I want to be straight with you: 'immune support' supplements are largely marketing fluff. The supplement market for dogs is enormous and mostly unnecessary. Most healthy dogs on a complete diet don't need anything extra, and when something specific is going on, like persistent ear problems, a broad multivitamin won't touch it. What's actually worth exploring depends on the detail. How old is your Spaniel, what does the vet say is causing the infections — yeast, bacteria, or both — and has anyone looked at diet or allergies as a possible trigger?

I hear you, and I understand the frustration of the same cycle repeating. But here's the honest truth: if it's allergy-driven, no supplement is going to fix the root cause — and 'immune boosting' isn't really a thing that works the way the packaging implies. That said, there is one supplement with genuine evidence behind it for exactly this situation. Omega-3 fatty acids — specifically EPA and DHA from fish oil — have solid research supporting their role in reducing inflammatory responses and supporting skin barrier function. In allergy-prone dogs, a compromised skin barrier in the ear canal can make infections more likely and harder to shift. Omega-3 won't cure an infection mid-flare, but used consistently it can reduce the frequency and severity if inflammation and skin health are part of the picture. Is Biscuit currently on any medication, and what does her diet look like?

That's useful. Supermarket own-brand kibble can be fine nutritionally, but senior formulas sometimes have lower omega-3 levels than ideal, and the ratio of omega-6 to omega-3 matters a lot for inflammatory conditions. Biscuit is a good candidate for a dedicated omega-3 supplement. My specific recommendation is YuMEGA Plus Skin & Coat Oil — it's a proper fish and starflower oil blend formulated for dogs with skin and coat issues, widely available on Amazon UK, and it's one of the few products I'd actually point someone toward with confidence for this kind of situation. It's a liquid you pour over food, which older dogs usually accept easily. Start her on the loading dose for the first month, then drop to maintenance. Don't expect miracles overnight — give it 8 to 12 weeks to judge properly. More importantly, I'd push the vet to do proper allergy testing or at least a food elimination trial. The omega-3 supports the tissue; finding the trigger stops the cycle.

YuMEGA Plus has a dosing guide on the bottle based on weight, and at 10kg Biscuit will fall into their smaller dog range — typically around 2ml daily at maintenance after the initial loading phase. Follow what's on the label for her weight rather than guessing, because the loading dose is higher and it does make a difference to how quickly you see results. One practical tip: pour it over her food just before serving so it doesn't oxidise sitting in a bowl. Store the bottle in the fridge once opened. And do keep a simple note of how often the ear infections come back — even just the month they start — so you have something concrete to tell the vet rather than going on memory.

Good plan. The supplement is worth trying, but the allergy investigation is honestly the more important thing — that's where you'll actually break the cycle rather than just manage it. If the vet is reluctant, ask specifically about a hydrolysed protein diet trial, which is one of the cleaner ways to rule out food allergy without expensive testing. Good luck with Biscuit — at 11 she's doing well to still be fighting, and sorting this out will make a real difference to her comfort.
