Most likely because the one you tried never arrived. Standard Lactobacillus-based probiotics largely don't survive a stomach running at pH 1-2, and are commonly dosed at 100-200 million CFU. ZeniPet leads with two spore-forming Bacillus strains that make the journey inside a protective endospore shell, at 6 billion CFU.

Fair catch. Four of the six strains are Lactobacillus or Bifidobacterium. They do useful work in the upper gut, so they earn their place. The distinction is that they support rather than lead. A product built only on those four is the thing we're arguing against.

The full panel with amounts is published above. Open "See the full ingredient list". In short: 6 billion CFU across 6 strains, a 120 mg six-enzyme blend, 400 mg pumpkin powder, 5 mg FOS and 120 mg Greek yoghurt powder, in a 4 g salmon-flavour soft chew.

Made in the UK. It's a complementary pet feed. It sits alongside a complete and balanced diet rather than replacing any part of it.

By weight: half a chew for dogs up to 5 kg, one chew from 5-18 kg, two chews from 18-36 kg, three chews above 36 kg. Given daily, with or without food. The full table with jar durations is in the dosing section above.

This is the most common reason a supplement fails, which is why the format isn't an afterthought. It's a soft salmon-flavour chew given from the hand like a treat. No hiding it in cheese, no sprinkling something on a bowl and watching them walk away. If yours is the exception, that's exactly what the guarantee is for, and you won't have to post anything back.

Suitable from 12 weeks, with no upper age limit. If your dog is on medication, is unwell, or is being treated for anything ongoing, speak to your vet before adding this or anything else. It sits alongside veterinary care and doesn't replace it. Never stop something a vet has prescribed on the strength of a product page.

Yes. No diet change is needed, and it's designed to fit around whatever you already feed. If your dog is on other supplements or any prescribed medication, check with your vet first.

It depends entirely on your dog's weight, and we'd rather you did the arithmetic than be upsold. A jar is 30 chews: 60 days for a mini dog, 30 for a small one, 15 for medium, 10 for large. For a fair trial rather than a taster, aim for a couple of months of continuous use.

Digestion tends to settle first, often in the first week or two. The changes owners really want take considerably longer, and for some dogs most of the 90 days. We'd rather tell you that now than have you give up at week three thinking it's failed.

Then you get your money back and you keep the jar. Every dog is different, and we're not going to claim this works for all of them. That's the honest reason the guarantee is as long and as unconditional as it is.

Because everything is on the table. The full ingredient panel with real amounts is published above. The mechanism is explained well enough that you can check it yourself. And we carry the financial risk for 90 days. We built one of the strongest gut health formulas available in the UK, and we're confident enough to let you prove it at our expense.

No. There's no subscription on this page, no pre-ticked option, no toggle in the basket and nothing that renews later. You buy the jars you choose, once. If you come back it'll be because it worked, not because a card got charged automatically.

You have 90 days from delivery. If you're not convinced, tell us and you get a full refund. And you keep the jar. Nothing to post back, nothing to repackage.

Free UK shipping on every order, no minimum spend. The Itch & Paw Care Plan is digital and arrives by email as soon as you've ordered, so you can start reading before the jars land.

It is a real amount of money, and we won't pretend otherwise to someone who has already spent a great deal on things that didn't hold. What we'd say is that it's less than a single consultation at most UK practices, and the guarantee means the downside isn't "another £30 wasted". It's nothing.
