A note from the founder.
He scratched himself raw every night. Three vets. Five medications. Two food brands. Nothing worked. Then I found one piece of research that no one had mentioned to me — and it rewrote what I thought was wrong with him.
Me with Vinnie — he's 4 now. Eight months ago he couldn't sleep through the night. Now he does — and so do I.
My dog Vinnie is 4 years old. He started scratching when he was about two.
At first it was a paw lick. A quick scratch. We thought it was a phase.
Six months later he was scratching himself raw — biting his paws, rubbing his face on the carpet, chewing his belly at 2am until it bled.
Three vets. A specialist. Antihistamines, steroids, Apoquel, hypoallergenic kibble, single-protein, raw.
None of it fixed him. None of it.
It took the edge off briefly. Then the itching came back worse.
"I felt like I was failing him. He'd look at me like, 'why won't you fix this?' — and I genuinely didn't know what else to try."
One night around 2am — I was lying awake listening to him scratch in the kitchen — I sat up, opened my laptop, and went down a rabbit hole that I now realise I should have started months earlier.
One night at 2am I started reading veterinary research papers. And one phrase kept coming up — one I'd never heard before:
The gut-skin axis.
70-80% of a dog's immune system lives in the gut.
When that bacterial balance falls apart — kibble, antibiotics, stress — the gut wall gets leaky. Inflammation spills out. The immune system goes haywire.
The skin is the largest immune organ in the body.
When the gut misfires, the skin is the first place it shows up.
As itching. As redness. As paws he couldn't stop chewing.
"Every shampoo, every steroid, every antihistamine was treating the smoke. None of it was touching the fire."
2024 RCT: dogs given a probiotic + nutraceutical blend showed significantly less itching in two weeks vs placebo.
2025 clinical study: 27% improvement in perceived itch in just 14 days.
The science was already there. Most vets just weren't taught it.
I bought fifteen different supplements over two months. Some were £40 a tub.
Then I read the labels properly.
"I realised the supplement Vinnie actually needed didn't exist. So I decided to build it."
I called every veterinary nutritionist in the UK who would talk to me. I sat with formulators. I read every clinical paper I could find on dog probiotics and skin inflammation.
The brief I gave them was simple: build the supplement I wish I could have given Vinnie a year ago.
Five rules:
It took 12 months. Six rejected formulations. Hundreds of conversations. We landed here:
Each ingredient does something specific along the gut-skin axis. Nothing in there is decorative.
Week 2 — his stools firmed up. I noticed that before anything else.
Week 3 — scratching tapered. Not gone. But less. He slept through the night for the first time in months.
Week 6 — coat changed. Shinier. Less flaky. The red patches on his belly faded. He stopped chewing his paws.
By week 8, he was a different dog.
Calmer. More energy. Comfortable in his own skin in a way I hadn't seen since he was a puppy.
"I literally noticed one day — wait, you haven't been scratching. I cried. Genuinely."
I gave the formula to friends. Then their friends. Then we ran a small batch. Then a bigger one.
600+ verified owners. 4.8-star average. Most tell me variations of the same story I've just told you.
A small selection of the messages we get every week.
"She's like a different dog."
Bella scratched and chewed her skin every single night for nearly a year. Two rounds of steroids, sensitive food, antihistamines — nothing held. Six weeks on Vinnie and she's barely scratching at all. Coat looks shiny again. I cannot recommend this enough.
"His belly was hot to the touch. Now it's not."
Tried heaps of sensitive dog shampoos. None worked. Murphy was miserable and was driving us miserable. We got Vinnie because nothing else had worked and we had nothing left to try. Three weeks in his stools were better. Eight weeks in he's a much healthier, less itchy pup.
"I'd tried everything the vet recommended."
Honestly I was sceptical. Two vets had given us the same advice — stronger meds. But Daisy was waking up at night to scratch and I'd run out of patience. The itching significantly decreased by week three. By eight she's finally comfortable. Wish I'd found this a year ago.
Not a generic returns policy. My personal one. If your dog isn't visibly better in 30 days — calmer, less scratching, firmer stools, healthier coat — email me and I'll give you every penny back. No forms. No hassle.
If you're where I was 12 months ago — exhausted, frustrated, out of ideas — please give Vinnie a try.
