I read the back of every dog joint supplement I could find. Not one told me the truth.

So I started making the one I couldn't buy. This is the honest story behind Fennpet.

It started with my own dog. Somewhere around eight, the stairs got slower. The stiff mornings. The way he stopped jumping onto the couch and just… looked at it. I told myself what everyone tells themselves: he's getting old, that's all.

But it nagged at me. He still wanted the walk. He still met me at the door. He just moved like it cost him something now. And I wasn't ready to file that under "nothing I can do."

So one night, with him asleep on the floor, I did what any worried dog owner does at 10pm — I went looking. And what I found genuinely annoyed me.

The two words that made me distrust the whole shelf

I bought a joint chew. Then another. Nothing much changed. So I started actually reading the labels — and the same two words kept showing up: "proprietary blend."

It sounds official. What it really means is: we won't tell you how much of anything is in here. You can't tell if there's a useful amount of glucosamine, or a pinch so it can go on the front. I was buying hope with a hidden label. That's when it stopped being about one product and started being about the whole category.

What I learned about ageing joints

The more I read, the clearer it got. Joints rely on specific building blocks — glucosamine and chondroitin for cartilage, omega-3s and green-lipped mussel for everyday comfort, hyaluronic acid for lubrication. As dogs age, they use those up faster than they replace them. Support the supply, at a real dose, given daily — and you're working with the body instead of just watching the clock.

"I wasn't buying a bad ingredient. I was buying a hidden amount of a good one."

So I made the one I couldn't buy

I couldn't find a single chew that did all three things I wanted: a complete formula, doses printed on the label, and something my dog would actually eat every day. So — and I still can't quite believe I did this — I set out to make it. One rule above all the others: every milligram printed on the pot. No blends to hide behind, nothing for you to have to look up.

I worked on the formula until the numbers were ones I'd be happy to show any vet, made it for small and medium breeds, and — because none of it matters if the dog won't eat it — made it a soft, pork-liver-flavour chew. Then I gave it the only test that counted: my own dog, every day, for eight weeks.

I won't pretend it was a miracle. It wasn't. But somewhere around week six he started beating me to the front door again — and taking the back step without that little pause at the bottom. To me, that was everything.

What ended up on the pot

That's Fennpet. A single daily chew for ageing small and medium dogs, with the full formula printed right there on the label. Here's exactly what's in each daily serving:

Why the risk is on us, not you

Because I was the sceptical one, I built the guarantee I'd have wanted. Try Fennpet properly, and if your dog isn't moving more comfortably, you shouldn't pay for it. Every order comes with a 90-day money-back guarantee — keep the tub you opened, send back any sealed ones, and we refund you. Give it the eight weeks. Then let your dog tell you.
