"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 feed gut bacteria, support immunity & help dogs thrive

A dog whose immune system needs backup?
So much of their immune system relies on bacteria found in the gut. Turkey Tail feeds that bacteria directly. It's rich in polysaccharopeptides - compounds that act as prebiotics for the gut. That's the actual mechanism behind a resilient immune system, not a vague "immunity boost." Feed consistently and support the gut your dog's immune system depends on.
A dog recovering from illness or antibiotics?
Once again, it all comes back to the gut. Antibiotics strip their gut’s bacteria and illness challenges their immune system. Turkey Tail feeds the gut bacteria and restores and strengthens their immune response. Use consistently and see the difference for yourself.

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 Turkey Tail, full stop. No fillers or bulking agents, just the mushroom, extracted properly so the compounds that matter (polysaccharopeptides) are actually bioavailable. One ingredient, doing what it's always done.

Are there any known side effects associated with these supplements?
Our supplements are made from natural, single-ingredient whole foods, which are generally well-tolerated by most pets. However, as with any new addition to your pet's diet, there's a small chance of adverse reactions.
These could include digestive upset like diarrhoea or vomiting, especially if the supplement is introduced too quickly or in too high a dose initially. We recommend starting with a smaller dose and gradually increasing to the recommended dosage while monitoring your pet for any adverse reactions.
Additionally, if your pet has any pre-existing medical conditions or is currently on medication, it's always a good practice to consult with your veterinarian before introducing new supplements to their diet.
The duration it takes to observe noticeable improvements in your pet's health can vary based on several factors including the specific supplement, your pet's initial health condition and the consistency of supplementation. However, many pet owners report seeing positive changes within a few weeks to a month of consistent supplementation.
Digestive Health: Improvements in digestive health, such as reduced flatulence or better stool consistency, can often be noticed relatively quickly, sometimes within a week or two.
Skin and Coat Health: For benefits like a shinier coat or healthier skin, it might take a few weeks of consistent supplementation.
Joint Health: Improvements in joint health and mobility may take a bit longer, sometimes up to a month or more, as joint tissues take time to repair and regenerate.
It's crucial to follow the recommended dosage guidelines and maintain a consistent supplementation routine to see the best results. Additionally, every pet is unique, so what works quickly for one pet may take longer for another.
What is the shelf life of your tinctures?
Generally, the shelf life of our tinctures are 2 years from the date of manufacture, when stored as directed on the packaging.
We recommend checking the "Best By" date printed on the packaging of each product to ensure you are using it within the recommended timeframe. It's also advisable to store our supplements in a cool, dry place away from direct sunlight to maintain their efficacy and quality over time.
What is your return policy in case I’m not satisfied with the product?
We have what we like to call a 'this sh*t better work guarantee'.
If it doesn't work, we don't deserve your money. We made this for our own dogs first. And we stand behind it, completely. If you try it and don't see a difference, we'll refund you, no stress, no stupid hoops. Because your dog's health isn't a gamble. And neither is your money.
