They put it to the test on their dogs

One chew a day based on their weight. That's it.

1. By hand or straight into the bowl
2. Under 10 kg: 1 chew
3. 10 to 25 kg: 2 chews
4. 25 to 50 kg: 3 chews
5. Close the tub tightly and keep it away from heat
Week 1: they ask for their chew, the routine sets in.
Weeks 2 to 6: steadier digestion, a coat that starts to shine again.
Weeks 6 to 12: this is when the coat and the joints really change.

Your 90-day guarantee starts the day your order arrives. If you see no difference, you get your money back, even if the tub is open.

They all chose KROKZOO

Jessie is 9 and used to puff her way up the stairs. Six weeks on, she goes up to the first floor without stopping.

Camille R.

Benny was leaving fur all over the house. Two months later I hoover half as much and his coat shines.

Thomas L.

Poppy has always spat out every tablet. This one she takes like a treat, no negotiating.

Léa M.

My two Yorkies finally digest properly. No more nasty surprises every time we change their kibble.

Nicolas P.

I put off buying for ages because of the price. Two tubs later, I reorder without thinking twice.

Five essential benefits
for lasting health

Our veterinary team built the KZ‑01™ formula around five areas that are essential to a dog's health.

  • Skin & Coat Omega‑3 and vitamin E look after the skin and coat.
  • Hips & Joints Glucosamine and chondroitin support the joints.
  • Digestion Probiotics support the digestive system.
  • Immunity A healthy gut strengthens natural defences.
  • Heart Folic acid (vitamin B9) supports heart function.

Physiological doses, not overdoses

Your dog's body isn't built to cope with huge nutrient spikes.
KROKZOO gives him exactly what he can absorb, every day.

His nutrient levels on a 3-month standard course

High doses, taken for a short spell. The body doesn't store it all, and the shortfall comes back the moment you stop.

SHE TAKES IT LIKE A TREAT

"My dog has spat out every tablet for nine years. I've tried it all, cheese, pâté, a syringe. Now I hold out the chew and she swallows it without even checking what it is. That alone won me over."

Camille R. Verified purchase
★★★★★

YOU HAVE TO BE PATIENT

"I'm leaving a second review because the first one, at three weeks, was lukewarm. You really do have to give it time. It was around week six that Benny's coat changed, thicker, and he sheds far less. I hoover half as often as I used to."

Thomas L. Verified purchase

MY 10-YEAR-OLD SHEPHERD CLIMBS THE STAIRS AGAIN

"Elsa is ten and she used to stop halfway up the stairs. Two months on the chews and she goes straight up. I'm not calling it a miracle, but it's the only thing we've changed in her routine."

Sylvie M. Verified purchase
★★★★★

SIMPLE

"Two in the bowl every morning, that's it. My labrador doesn't even notice the difference."

Julien P. Verified purchase
★★★★★

THE PRICE PUT ME OFF AT FIRST

"Honestly, I thought it was pricey for a month. Then I added up what I was spending on salmon oil, joint capsules and probiotics, and I'm well ahead. With one thing to manage instead of three."

DIGESTION SORTED IN TEN DAYS

"My beagle had loose stools half the time, and always had. In about ten days it was sorted, and it's held for three months."

PARCEL ARRIVED IN TWO DAYS

"Ordered on a Tuesday evening, here by Thursday morning. Neat packaging, clear instructions on how much to give based on your dog's weight. Nothing to fault."

Léa V. Verified purchase

SHE COMES ASKING FOR IT

"The funny part is that she's worked out the timing. At eight o'clock she's sitting in front of the cupboard. I've never once had to coax her."

FINALLY, A FRENCH BRAND

"I was tired of ordering tubs from the United States, waiting three weeks and paying customs charges on arrival. Clear ingredients, made in France, that makes all the difference."

MY JACK RUSSELL IS TEN YEARS YOUNGER

"All right, I'm exaggerating a little. But he asks for the ball again in the evening, when he used to collapse the moment we got back from the walk."

FOR AN AGEING DOG

"I started when my setter turned nine, on the advice of my vet, who told me to get ahead of it rather than wait. He's livelier in the morning, no question about it."

EVEN MINE WOLFS IT DOWN

"My shiba turns his nose up at anything that isn't exactly his usual kibble. He ate the chew without a fuss. I never thought he would."

Ahmed K. Verified purchase

THREE MONTHS IN, THE VERDICT

"What I can see: a shinier coat, less shedding, and she's more playful in the evening. What I can't see: I thought it would change her breath, and it hasn't. On the whole, I'm buying again."

RESPONSIVE CUSTOMER SERVICE

"I ordered the wrong size. They replied in two hours and swapped it without quibbling. That counts."

TWO DOGS, TWO TUBS

"I buy it for my two beagles. The dose is set by weight and both of them eat it without any trouble. The only drawback is that the tub goes down fast when two of them are sharing it."

MY VET CHECKED THE INGREDIENTS

"I showed her the label before we started. She told me the doses made sense and that there was nothing pointless in there. It put my mind at rest going forward."

A LOVELY SURPRISE: THE COAT

NOTHING TO FAULT

"Three months, happy dog, tub finished. I'm subscribing again."

THE SMELL IS STRONG

"One small downside: when you open the tub, it smells quite strongly of fish. My dog loves it, I'm less keen. I suppose that's a good sign for the omega-3."

MY OLD BOUVIER

FAQ

That's THE question, and it's why we worked on the chew before anything else. It isn't a tablet or a capsule: it's a soft chew, given by hand or dropped in the bowl.

With fussy dogs, the ones who spit everything out, that's where the difference shows. And if yours really won't have it, the 90-day guarantee is there for exactly that.

Two a day, morning and evening, for a medium-sized dog. One tub holds 60 chews, so a month's worth.

  • Under 10 kg: 1 chew a day
  • 10 to 25 kg: 2 chews a day
  • Over 25 kg: 3 chews a day

The exact dose is on the tub label as well.

It depends what you're looking at, and that's normal: each active ingredient works at its own pace.

  • Digestion, in one to two weeks. That's the probiotics.
  • Energy, somewhere between three and six weeks.
  • Coat, more like two to three months: a growth cycle takes six to eight weeks, and nothing goes faster than that.
  • Joints, from the third month onwards.

Consistency is what counts, not the dose. A dog who gets it two days out of three won't see the same results.

A formula built around five areas, with nothing you don't need:

  • Omega‑3 and vitamin E for skin and coat
  • Glucosamine and chondroitin for cartilage and joints
  • Probiotics for gut flora
  • B vitamins for metabolism and vitality
  • Folic acid (vitamin B9) for heart function

No artificial flavouring. The full list and the amounts are on the label, nothing hidden behind a "proprietary blend".

KROKZOO is a food supplement, not a medicine, and it doesn't replace any treatment.

If your dog is on medication, being treated for a condition, or is pregnant or nursing, speak to your vet before you start. They're the one who knows your dog's history. Show them the label and they'll see in thirty seconds whether there's anything worth flagging.

From 6 months, once growth is well under way. Before that age a puppy has its own specific needs: ask your vet for advice.

For an ageing dog there is no upper limit, and that is often when it makes the most sense. Better to start before the first stiffness sets in than after.

Away from light and heat, with the lid firmly closed. No need to refrigerate.

Once opened, the tub keeps until the date printed underneath. And keep it out of your dog's reach: the chews taste good, and some dogs would happily help themselves.

You have 90 days. Not 14, not 30. Three months is how long it takes to judge honestly, including the coat and the joints, which are the slowest to change.

If you're not convinced, we'll refund you, even if the tub is open. You write to us, we reply, and we won't ask you to explain yourself.
