Irish Setter IBD & Gas: Best Probiotic

An Irish Setter with inflammatory bowel tendencies is a really specific situation — and it matters, because IBD-prone dogs need a probiotic that actively supports the gut lining and reduces fermentation, not just a generic multi-strain blend that can sometimes add fuel to the fire. Probiotics can genuinely help here, but quality and strain specificity vary enormously, and what works for one dog may do nothing — or worse — for another. Before I point you anywhere, can you tell me: has a vet confirmed the IBD tendency, and is the gas mainly right after eating or does it persist through the day? Also, is your Setter on any current medication or a prescription diet?

That's really helpful. Vet-confirmed IBD managed through diet is actually a good baseline to work from — it means his gut isn't in crisis, just chronically irritable. The post-meal gas timing tells me the issue is likely in fermentation happening in the small intestine rather than deeper down, which is important because you want a probiotic that colonises high up and reduces that fermentation window. One thing worth flagging: grain-free kibbles can sometimes be high in legumes like peas and lentils, which are fermentable carbohydrates — that may be contributing more than you'd think. Has his gas been consistent since he started that particular kibble, or did it predate the diet change?

Good — that rules out the kibble as the root cause, though it may still be amplifying things. For a dog like yours — IBD-prone, chronically gassy post-meal, adult and otherwise stable — I'd recommend Protexin Pro-Kolin Advanced. It's a paste format, which means it delivers the active strains directly and consistently without the degradation you get in some powder or treat formats. It contains Enterococcus faecium, which has solid evidence behind it specifically for dogs with gut inflammation, plus kaolin and pectin which calm the gut lining directly. It's not a supplement aimed at healthy dogs — it's genuinely formulated for dogs with sensitive or compromised gut function. Give it 4–6 weeks at the maintenance dose before judging results, and ideally log his symptoms weekly so you have something concrete to tell your vet. That vet relationship matters here — if you're not seeing improvement after 6 weeks, it's worth going back and discussing whether a low-antigen diet trial is the next step.

For a dog with confirmed IBD tendencies, ongoing low-dose use makes more sense than treating it like a course. Think of it less like antibiotics and more like a daily support tool — his gut doesn't have the resilience a healthy dog's would have, so the benefit largely persists only while you're using it. That said, some owners find they can taper to every other day once things stabilise, which is worth trying after the first couple of months if he's doing well. The vet should know you're using it — it's very safe and well-regarded clinically, but keeping them in the loop means they can factor it into any future decisions.

That's exactly the right approach. Keep notes on gas frequency and any changes in stool consistency — those two things together will give you a clear picture of whether it's working. Protexin Pro-Kolin Advanced is widely available on Amazon UK and through most vet-adjacent retailers. Good luck with him — Irish Setters are worth the extra effort.
