This is a specific conversation about Dog gut health — probiotics and digestive support — ask about yours and get one honest answer for your exact situation.

Probiotics can make a genuine difference for dogs — but quality and strain specificity vary enormously, and what helps one dog may do nothing for another. A 14-year-old Cavalier with very slow gut motility is a specific and quite delicate situation, so I want to get this right for you. What symptoms exactly are you seeing — how infrequent are the stools, and is there any straining, bloating, or appetite change alongside it? And has your vet had a look at this, given her age?
She's 14, a female Cavalier. She's only going every 3 or 4 days, sometimes longer. No real straining, the stool is just very small and dry when it does come. She eats okay but not with much enthusiasm. The vet has checked her over — no blockage, no obvious disease. They said her gut is just slowing down with age and suggested trying a probiotic or fibre supplement.

That picture makes sense for a senior Cavalier — age-related reduction in gut motility is real, and the dry, infrequent stools tell me there's both a motility issue and likely some dehydration in the colon. Before I point you to a specific product: is she on any medication? Cavaliers at 14 are often on heart medication, and some of those can affect gut function too. And what's her current diet — wet, dry, or mixed?
Yes, she's on Vetmedin and Frusemide for her heart. She eats mostly dry kibble with a small amount of wet food mixed in. We do try to get water into her but she's never been a big drinker.

That's really useful — Frusemide is a diuretic, which absolutely contributes to drier stools because it pulls fluid from the body, including the colon. You can't stop the medication obviously, but it means keeping gut moisture up is especially important for her. My clear recommendation here is Protexin Pro-Kolin Advanced. It's a paste rather than a powder, which makes dosing easy for a small senior dog, and it combines a well-researched probiotic strain (Enterococcus faecium) with kaolin and pectin — the pectin in particular helps retain moisture in the colon and supports gentle, regular transit. It's not a laxative so it won't cause urgency or cramping, which matters for an older dog. It's widely used by UK vets and available on Amazon. I'd also gently suggest adding a small amount of tinned plain pumpkin or switching to a higher-moisture wet food — the medication means she needs every bit of hydration support she can get.
That sounds really sensible. Is the paste easy to give? She's quite fussy.

Most dogs take it without a fight — it has a mild flavour and you can squeeze a small amount onto your finger or onto the wet food. For a fussy senior I'd mix it into the wet food rather than giving it directly. Start with the lower end of the dose range for her weight. Give it a consistent two-week trial before judging whether it's working — gut motility in older dogs responds slowly, so don't expect a dramatic change in the first few days.
Great, thank you. I'll give it a try alongside more wet food.

That combination — Pro-Kolin Advanced plus increased moisture in her diet — is genuinely the right approach for her situation. Keep a simple note of how often she's going so you can report back to your vet clearly. If she goes more than five days without a stool or seems uncomfortable, do loop the vet back in. But for a dog whose gut is slowing with age on a diuretic, this is a sensible, low-risk place to start.
