Formulated With Purpose

TailFuel™ is built on two ingredients, at doses that actually do something: 1,000 mg of organic turkey tail mushroom for immune support, and 1 billion CFU of live probiotic so he absorbs it. No proprietary blends, no eleven-mushroom label padding, no guessing what's inside.

Every Breed. Every Size. Every Senior Dog.

Whether your dog is a German Shepherd, a mixed breed, or anything in between, ageing digestion needs the same support. TailFuel™ works with any breed and size — you just change the scoop count: one a day up to 11 kg, two up to 23 kg, three above that.

Frequently Asked Questions

What if my dog doesn't take to it?

Every order is covered by our 60-day money-back guarantee. Give it a fair trial — daily use for at least six weeks — and if you're still not happy, email us with your order number and we'll refund you. Keep the jar; there's nothing to send back.

Why turkey tail mushroom for dogs?

Turkey tail has been used in wellness traditions for centuries and is one of the most studied functional mushrooms today. TailFuel™ combines 1,000 mg of organic turkey tail with 1 billion CFU of live probiotic — the mushroom supports normal immune function, and the probiotic helps your dog absorb it.

How do I give it to my dog?

One bacon-flavoured scoop a day, stirred into a meal — no pills, nothing to crush or hide. Dogs up to 11 kg have one scoop, 11–23 kg two, over 23 kg three. Thirty scoops per jar, and the scoop is in the lid.

Can I give it alongside other supplements or medication?

TailFuel™ is designed to fit into a normal daily routine. If your dog is on medication, pregnant, nursing, or has a health condition, check with your vet first — the same advice we'd give for any new supplement.

When will I notice a difference?

Every dog is different. Digestion usually settles first, within the first fortnight. The energy changes tend to land between weeks three and six. Consistency matters more than speed, which is exactly why the guarantee runs 60 days and not 14.†

How long does shipping take?

Delivery is free to the UK and Australia, and orders typically arrive within 2–5 working days. Order before 2pm on a working day and it's dispatched the same day, with a tracking link by email as soon as it leaves us.
