This is a specific conversation about Dog supplements — what's actually worth it — ask about yours and get one honest answer for your exact situation.

Two dogs, same age, both with dull coats — that's actually a useful clue. When two dogs in the same household show the same issue at the same time, it usually points to diet or environment rather than anything breed-specific or medical. The supplement market for dogs is enormous and mostly unnecessary, but coat condition is one of the few areas where there's real evidence that something can help. Before I point you anywhere, can you tell me what they're both eating, and is the dullness recent or has it always been this way? Also, any itching, flaking, or just flat-looking fur with no other symptoms?
They're both on the same dry kibble, a mid-range brand. The dullness has crept up over the last six months or so. No itching or flaking, just really lacklustre coats — my Poodle especially used to have a beautiful shine.

That timeline and the fact that both dogs are affected strongly suggests a dietary fat deficiency — specifically omega-3 and omega-6 fatty acids. Most dry kibbles, even decent ones, are low in these because the fats degrade during processing and storage. It's not a sign the food is bad, it's just a limitation of the format. This is genuinely one of the cases where a supplement makes sense. What are they currently eating, and roughly how long have you had them on this kibble?
It's Harrington's Complete. They've been on it about eight months — we switched when our previous brand got reformulated. That roughly lines up with when the coats started looking worse.

That timing is telling — the switch lines up almost exactly with the coat change, which points clearly to the new food being lower in quality fats than whatever they were on before. Harrington's is a reasonable kibble but it's not especially rich in omega fatty acids. The fix here is simple and well-evidenced: add an omega oil supplement. I'd recommend YuMEGA Dog by Lintbells. It's an omega-3 and omega-6 oil blend specifically formulated for coat and skin, it's well-studied, and it's one of the few supplements in this space with genuine vet backing rather than just marketing. You pump it over their food daily — the dosage is by weight, so you'd use it for both dogs from the same bottle. Most owners see a visible difference in coat texture and shine within four to six weeks. It's available on Amazon UK and reasonably priced for what it is.
That sounds straightforward. Is there any reason to look at the food itself rather than just adding a supplement on top?
inparticular.ai
Honestly, yes — and it's worth considering. If switching to a food with higher-quality fat sources, like a cold-pressed or raw-coated kibble, solves the problem at the root, that's better than patching a dietary gap indefinitely. But changing food for two dogs is disruptive and expensive, and you won't know if it works for weeks. The oil supplement is cheap, easy, and will tell you quickly whether fatty acids are the issue. If the coats come back beautifully in six weeks, you have your answer. At that point you can either stay on the supplement or use it as a reason to upgrade the food. I'd start with the YuMEGA, see how they respond, and then decide.
Makes sense. One bottle for both dogs — is the dosing going to be complicated with two different sizes?
inparticular.ai
Not at all. The pump gives a measured dose and you adjust by weight. Poodles and Bichon Frises are both relatively small breeds, so you're probably looking at similar amounts for each — check the label for the exact weight bands but it's usually one or two pumps per dog per day. One bottle will last you a good while. Just add it to their food at mealtime and you're done.
