What Owners Say
"We often had problems with too-soft stool and mucus in it. After about 1.5 weeks there was a clear difference — now we rarely have stool problems."

"Our girl won't eat grass anymore or lick her paws like crazy. All within two weeks. She didn't like it plain as a snack though, so I chopped two pieces small and snuck them into her morning food."
★★★★★ · Verified purchase, Germany · 14 July 2026
"My dog gets stomach/gut issues from these, even with just one piece — afterwards she runs off to eat grass to settle her stomach. They also smell very strong, almost like Maggi seasoning."

FAQ
Do these chews need to be refrigerated?
No. The brand states the chews don't need any special storage — just keep them in a cool, dry place (a cupboard is fine) and close the lid after each use to keep them fresh.
At what age can a puppy start these probiotics?
The product listing states the chews are suitable for dogs from 4 months of age.
How is this different from a plain probiotic supplement?
It combines three mechanisms rather than probiotics alone: a prebiotic fibre (fructo-oligosaccharides) to feed good bacteria, a live probiotic strain (Calsporin), and a postbiotic (EpiCor Pets), alongside pumpkin and flaxseed for additional digestive and coat support.
My dog won't eat the chews plain — what can I do?
Several reviewers with picky eaters report success chopping the chews into small pieces and mixing them into the dog's regular food rather than offering them as a standalone treat.
Can this product cause digestive upset instead of helping?
Most reviews report improvement, but at least one reviewer reported the opposite — her dog developed stomach upset even from a single piece. As with any new supplement, introduce it gradually and watch for reactions; stop use and consult a vet if symptoms appear.
