I’ll admit that I’m not usually someone who is loyal to a particular brand, and I never really understood the concept…until I discovered Fettle. I have complete confidence that what I’m giving my dogs is high quality, carefully curated with their best interests in mind, and delivers exactly what it promises... I can’t imagine using anything else because, at the end of the day, Fettle works.

what our happy customers are saying
A mushroom-backed way to ease stress, support calm & help dogs settle
A dog who struggles to switch off?
Some dogs never quite settle - pacing, panting, always half-alert. Reishi contains triterpenes, compounds long used to support the body's response to stress. It’s the actual mechanism behind a calmer nervous system. Feed consistently and support the nervous system your dog relies on to switch off.
A dog whose liver needs support?
The liver works constantly, filtering out everything a dog's body doesn't need. Reishi's triterpenes have long been used to support healthy liver function. By feeding Reishi when the body is in need, it will help the liver clear toxins and do what it does best.
Easy to store and add to food
Store in a cool, dry place like your cupboards and use the dropper to add the tincture onto your dog’s food. It’s easy and convenient, but it will make such a difference.
Just 1 natural ingredient
Most supplements are a long list of ingredients doing a vague job together. This one isn't. It's Reishi mushroom, full stop. No fillers or bulking agents, just the mushroom, extracted properly so the compounds that matter (triterpenes) are actually bioavailable. One ingredient, doing what it's always done.
