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 10-year-old with slowing digestion and reduced appetite is exactly the kind of case where the right gut support can really shift things, but it's worth being precise about what you're dealing with. What breed and age is your dog, what symptoms are you seeing, and have you had a vet look at this yet?
He's a 10-year-old Beagle, about 13kg. Over the last few months he's been eating less, seems to take ages to digest his food, and occasionally has loose stools. The vet checked him over and said there's nothing seriously wrong — just age-related slowdown — but didn't really suggest anything specific.

That's a really common picture in senior Beagles — the gut microbiome does change with age, motility slows down, and appetite regulation becomes less reliable. Good that the vet has ruled out anything serious. Can I ask a couple of things: is he on any medication at the moment, and what are you currently feeding him — kibble, wet food, raw, or a mix?
No medications. He's on a senior dry kibble, same brand for the last three years. We add a bit of warm water to it to help him eat it more easily.

That's actually a helpful detail — adding warm water is a good move for senior dogs as it aids initial breakdown. For a 10-year-old with this specific combination of slow digestion, occasional loose stools, and reduced appetite, I'd point you toward Protexin Pro-Kolin Advanced. It's a paste rather than a powder or capsule, which makes dosing straightforward and absorption faster. It combines a clinically studied probiotic strain (Enterococcus faecium) with kaolin and pectin, which help regulate stool consistency in both directions — useful when you're seeing intermittent looseness. The paste format also means you can mix a small amount into his softened kibble without fuss. At his age and weight, one syringe daily for a couple of weeks typically gives a fair read on whether it's helping. It won't fix a sluggish appetite overnight, but stabilising the gut environment often has a knock-on effect on how interested a dog is in food.
That sounds sensible. Is it something he'd need to stay on permanently or just use as a course?

For age-related gut changes, most owners find a middle path works best — a two-week course to begin with, then dropping to every other day or a few times a week as maintenance. Senior dogs often benefit from ongoing low-level support rather than a one-off course, because the underlying microbiome changes don't reverse. That said, some dogs stabilise well after an initial course and only need it again if symptoms return. It's genuinely worth keeping a note of his stool consistency and appetite during the first two weeks so you have something concrete to go back to your vet with if things haven't shifted.
Really helpful, thank you. I'll give it a try.

Good luck with him. Beagles at ten are still very much in their stride with the right support — a stable gut makes a noticeable difference to energy and appetite in older dogs. If after three weeks you're not seeing any change in the loose stools or his appetite is still really poor, it's worth going back to the vet to look at thyroid function and B12 levels, which can also drive exactly these symptoms in senior dogs.
