“I liked that the language on the site was honest. It didn't promise miracles, so I trusted it enough to try.”
“It feels like a proper part of his routine now, and his coat is genuinely softer.”

Anything you'd like to ask?
What does it actually do?
It's a daily treat made to support the things that quietly matter as dogs get older — healthy ageing, everyday vitality, mobility and a shining coat.
Is it suitable for my dog?
Yes, for adult and senior dogs of any breed or size, usually from around 7 years upwards. If your dog is on medication, have a quick word with your vet.
How long before I notice a difference?
Nutrition works gradually. Most owners describe small changes over several weeks — first in coat, then in easier mornings.
Is it backed by science?
Yes. Our ingredients were chosen after reviewing published scientific research. You can read more in our Science section.
Where is it made?
Formulated and made in the UK, in small batches.
