"Balance the gut and your dog benefits head to tail. That's why I recommend Kooper's."

"Cuddles don't knock me out anymore."
Our labrador's breath could clear a room. One serving a day and within it was few weeks the smell had gone, four months later still going strong.
"Actually works"
Dental sticks did nothing. This is the first thing that's actually worked
"Kooper's has fixed my dog's breath"
Her breath was the first thing everyone noticed, and not in a good way. A month in it's so much better, thank you Koopers!
Does this soundfamiliar?
of the immune system lives in the gut — where the mouth’s ecosystem begins
of bad breath that survives a professional clean is coming from deeper than the teeth
of persistent breath issues trace back to the gut
If the breath’s back after the dental, this is for you.
Bad breath that won’t quit is agutsignal, not a teeth one
The mouth is the start of the digestive tract — when the gut microbiome is out of balance, fermentation and gas travel back up as odour. Chews and additives only mask the exit. Kooper’s rebalances the source with prebiotics, probiotics and postbiotics.

You'll spot the first changes within the first few days, with bigger, more noticeable differences over the next couple of weeks. Keep it up and the gut stays in balance, so whatever your dog is dealing with doesn't creep back; by around 90 days, a whole new dog.
Kooper's is suitable for any dog from 12 weeks old, with the daily amount scaled to their weight. It's designed with sensitive tummies in mind, and a great fit for dogs prone to allergies too.
Yes, it can sit alongside other supplements and your dog's normal diet with no issue. If they're on any prescription medication, just check with your vet first.
Honestly, they'll eat it; we named Kooper's after a dachshund who'd only accept fresh salmon, and even he wolfs it down. Of 855 dogs we sampled, just 6 turned their noses up at the beef flavour - about as rare as a kid turning down chips.
Made here in South Yorkshire and third-party tested by IFP Labs, with every ingredient active and human-grade - no fillers, nothing hidden. Every dose is printed on the pack, so you can see exactly what your dog's getting.
Because a chew has to hold its shape, which means binders and fillers, often making up more than half the treat. A powder doesn't, so every scoop is active ingredients and nothing else, and it mixes straight into any food. Put simply: real health isn't shaped like a treat.

Feed Kooper's daily for 90 days. If your dog isn't happier and healthier, we'll refund every penny — keep the product, no forms, no fuss.
The risk is ours, not yours.

Her breath doesn't smell like death anymore
We'd done the chews, the additive, even the professional clean — it always came back. A few weeks of Kooper's and I can actually have her on my lap.
Hannah W.It was coming from his stomach the whole time
Makes so much sense now. The gas has eased right off and the breath along with it.
Bradley O.Cuddles are back on
He's a lap dog and the breath was genuinely my only complaint. Not anymore.
