Try TailFuel™ for 60 days. If your dog is no better for it, email us and we'll refund you in full.

No return needed — keep the jar. We're not going to make you post powder back across the country. No return fee, no store credit: your money goes back to the card you paid with, usually within 5–10 working days.

One thing we ask: give it a proper go. Turkey tail and probiotics need a few weeks before there's anything worth noticing. That's exactly why this guarantee runs 60 days and not 14.

One scoop a day, stirred straight into his normal food. That's the whole routine — no pills to hide in cheese, nothing to remember twice a day.

Up to 11 kg: one scoop. 11–23 kg: two scoops. Over 23 kg: three. Thirty scoops per jar, and the scoop is in the lid.

It's bacon-flavoured and dissolves into wet food or coats dry kibble evenly, so there's nothing left in the bowl to pick around. Most owners tell us their dog finishes it faster than the food it's mixed into.

Store somewhere cool and dry with the lid closed. If your dog is on prescribed medication or being treated for anything, have a word with your vet before you start.

TailFuel™ is a complementary food supplement, not a medicine. Two ingredients: organic turkey tail mushroom and a live probiotic culture. No grains, no fillers, no artificial anything.

It's made for senior dogs, and there's no upper age limit — plenty of our customers have dogs of 13 and 14 on it.

That said, we'd rather you asked than assumed. If your dog is on prescribed medication, being treated for anything, pregnant, or you've recently found a new lump, speak to your vet before starting. Nothing we sell replaces veterinary advice, and we'd never pretend otherwise.
