A little bit about us
We're dog people first. The kind who read the label on our own food, then looked down at the bowl and thought - why not the same for them? So we built Kooper's: honest, human-grade daily nutrition, formulated with vets and made in the UK, with nothing to hide. Because the people who love their dogs hold a higher standard. We're here to meet it.
It started with one dog. Kooper , a chocolate-and-tan dachshund, and a simple, stubborn belief: that he deserved the same standard we hold for our own food. Not a chew dressed up like a treat. Not an impressive-looking label hiding cheap filler. Real nutrition, with every ingredient and every dose out in the open.
So we spent months with vets and nutritionists building it properly, from the gut up. Eighteen human-grade ingredients, each one there to do a job. No binders, no fillers, no proprietary blends to hide behind. Made in the UK, and tested on hundreds of real dogs - including some very fussy eaters - before we'd put our name on it.
We're a small team who happen to love dogs a little too much. Kooper's is our way of giving them more of the good days and we think the dog reading over your shoulder right now deserves exactly that.
Made Properly. No Shortcuts.
Real transparency, from our facilities to the bag.
Kooper's is developed alongside vets and pet nutritionists in state-of-the-art UK facilities, where every formula is researched, tested and refined before it reaches your dog's bowl.
Every batch is blended and packed right here in the UK to strict manufacturing standards - so we can stand behind the quality of every single scoop.
Kooper's 18 human-grade ingredient formula was developed alongside a team of registered vets, built on a clear gut-first mechanism with every dose published. No proprietary blends, nothing hidden.
Before anything is sealed and packed, every batch goes through strict manual safety and quality checks - because your dog deserves the same standard you'd hold for yourself.

FAQ
The honest answers, before you ask.
Kooper's is a powder that mixes straight into the food they already eat - no tablets, no chews, no bribery. It's been tested on over 800 UK dogs, including some of the fussiest eaters, and it passed. The natural beef flavour does most of the work. For the truly stubborn ones, mix the powder with a little water first to form a gravy and stir it through - works every time. And if your dog still won't touch it, our 90-day money-back guarantee means you've lost nothing.
Gut improvements and better stools can show within days; fresher breath and less itching in two to four weeks. Consistency is where it becomes a daily habit - more good days, for longer.
Every dose is published - no proprietary blends, no hidden quantities. Vet-formulated with 18 human-grade ingredients and a clear gut-first mechanism behind every scoop. And if you don't see real results within 90 days, we'll refund every penny. No forms, no fuss. The risk is ours, not yours.
