Probiotics for two Greyhounds with different gut needs

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. Two rescue Greyhounds with different digestive histories is actually a really common situation, and finding something that works safely for both without running two completely separate supplement routines is a legitimate goal. Before I point you anywhere, it helps to know: how old are each of them, what digestive issues are you actually seeing in each dog, and have either of them been seen by a vet about their gut symptoms specifically?

That's a helpful picture, thank you. Loose stools with a stress history in Dora and post-meal gas and bloating in Bruno actually overlap more than they sound — both point to gut microbiome imbalance rather than structural problems, which is reassuring. Greyhounds as a breed have slightly unusual gut physiology compared to other dogs: they tend to have a higher proportion of certain bacterial populations and can be sensitive to dietary changes. Before we go further — is their diet the same, and have you noticed whether Bruno's bloating is worse on certain foods or after eating quickly?

That's a really important detail — Bruno's bloating coinciding with the raw food transition is almost certainly connected. Raw diets shift the microbial balance quite significantly, and some dogs, especially older ones, take longer to adapt. The fast eating compounds it too. For Dora, the soft stools predate the diet change, so she likely has an underlying microbiome that just runs looser under any stress or change. Given all of that, my clear recommendation for both of them is YuMEGA Tummy by Lintbells. It's a powder you sprinkle on food, contains a well-evidenced strain — Enterococcus faecium — alongside prebiotic fibre and kaolin, which helps firm stools and settle the gut lining. It's gentle enough for daily long-term use, strain-specific enough to actually do something, and because it works on both the loose-stool and gassy-bloating end of the spectrum, it's genuinely suitable for both dogs on the same feeding routine without any awkward dosing differences. One tub, one scoop per dog per meal. I'd also suggest a slow-feeder bowl for Bruno alongside it — that'll take pressure off the probiotic to do all the work.

For Dora's stools, most owners see meaningful firming within two to three weeks of consistent daily use. Bruno's bloating should start easing within the first week if the raw food transition is the main driver — gas tends to respond faster than stool consistency because it's more directly tied to fermentation activity in the colon. What to watch for: a temporary increase in gas in the first few days is normal as the gut flora shifts — don't stop at that point. If either dog develops vomiting, completely stops eating, or you see blood in stools, that warrants a vet call rather than continuing the supplement. And if Dora's stools haven't improved at all after four weeks of daily use, it's worth a vet visit to rule out something like EPI or a low-grade parasite load, which probiotics alone won't fix. But based on what you've described, I'd be reasonably optimistic for both of them.

Perfect combination. Give it a full month before you judge it — and if you want a slow feeder recommendation too, the LickiMat Splash or a basic maze bowl both work well for Greyhound muzzle shapes, which are narrower than most breeds. Good luck with both of them — rescue Greyhounds are brilliant dogs and their guts usually settle beautifully once the microbiome catches up.
