Founder's Letter Pet Health

A note from the founder.

I spent 12 months and everything I had trying to stop my dog scratching. What I found changed everything.

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.

The 2am moment

If you're reading this, I think I know how you feel.

An itchy dog scratching — the all too familiar sight
If your dog spends more time scratching than resting — this is exactly what we lived through.

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.

The discovery

The itch wasn't coming from his skin.

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.

The gut microbiome — where 70 to 80 percent of a dog's immune system lives
Inside the gut microbiome — where 70-80% of a dog's immune system lives.

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.

What didn't work

So I tried every gut supplement on the market. They were almost all rubbish.

I bought fifteen different supplements over two months. Some were £40 a tub.

Then I read the labels properly.

1
Underdosed probiotics.Most were 100 million CFU — a tenth of what research suggests dogs actually need to make a difference.
2
The wrong strains.Many used probiotic strains that get destroyed by stomach acid before they reach the colon. So the bacteria you paid for never got to where they're supposed to live.
3
Filler. So much filler.Cheap binders, anti-caking agents, "flavour enhancers". I'd be paying £40 for a tub that was 60% padding.
4
One ingredient at a time.Probiotic on its own. Or just bone broth. Or just turmeric. Nothing that addressed the gut-skin axis as a system.

"I realised the supplement Vinnie actually needed didn't exist. So I decided to build it."

If your dog is suffering, you don't need another shampoo. You need to address the cause.

12 months in the lab

I worked with vets and nutritionists for a year to build what didn't exist.

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:

1
Clinical doses or nothing.If the research said you need a billion CFU of L. Plantarum to shift the microbiome, that's what we'd put in. No half-doses.
2
Address the whole axis.Seed the gut. Feed the bacteria. Repair the lining. Calm the inflammation. Not one of those — all of them.
3
Zero filler.Every single gram in the pouch had to do something. No padding. No bulking agents. 100% active.
4
Strains that survive stomach acid.L. Plantarum was the obvious choice — acid-tolerant, reaches the colon alive.
5
One scoop. Any food.If it's a faff, owners stop using it. So we made it a powder you sprinkle on whatever you already feed.

It took 12 months. Six rejected formulations. Hundreds of conversations. We landed here:

🦠L. Plantarum1bn CFU
🌾Orafti Inulin (prebiotic)200mg
🦴Bone Broth Powder505mg
🌻Golden FlaxseedOmega-3s
🍄Reishi Mushroom185mg
🌿Turmeric Root75mg
🌱Ashwagandha200mg

Each ingredient does something specific along the gut-skin axis. Nothing in there is decorative.

Vinnie, 8 weeks later

Then I started giving it to Vinnie.

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.

"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.
