Bailey is 11 and the vet told us to just keep an eye on things. This gives me something I can actually DO every morning. She licks the bowl clean, every single day.

What Pet Parents Say
★★★★★
My picky senior boy eats around everything I hide in his food. This? He licks the bacon powder off first. Three weeks in and his tummy has been so much calmer.†

Week 4 and Cooper is waiting at the door for his walk again. He just seems brighter and more like his old self. I wish we had started this sooner.†
Linda R.
★★★★★
I've tried so many supplements that did nothing. One scoop, no pills, no wrestling matches. Finally something simple that actually fits into our morning routine.
Deborah K.
★★★★★
Moose thinks it's a treat. Zero fuss at breakfast, and his digestion has been noticeably more regular since we started. That alone is worth it for us.†

★★★★★
Duke is 12. I wanted to support his immune system between checkups and this checks every box. Love that it's just two clean ingredients and nothing else.†

Your Questions, Answered
Why turkey tail mushroom for dogs?
Because it's earned its reputation. Turkey tail has been used in wellness traditions for over a thousand years and is one of the most studied functional mushrooms in the world. KOIRRA® uses organic fruiting-body turkey tail (the part of the mushroom traditionally valued) paired with 1 billion CFU of probiotics to support your dog's daily gut balance and immune system.
How do I give KOIRRA® to my dog?
One bacon-flavored scoop a day, stirred into a meal. Each jar contains 30 servings, a full month of daily support for most dogs. No pills to hide, nothing to crush: the bacon flavor does the convincing.
Can my dog take KOIRRA® alongside food or other supplements? ‡
KOIRRA® is designed to fit into a normal daily routine and is given with regular meals. If your dog takes medication, has a health condition, is pregnant or nursing, we recommend checking with your veterinarian first, the same advice we'd give for any new supplement.‡
When will I notice a difference?
Every dog is different. Some dog parents report changes in digestion within the first few weeks, while for others it takes a full month or more of consistent daily use.* Supplements support the body over time: consistency matters more than speed. That's why every jar covers a full 30 days.
What if my dog doesn't like it?
Every order is covered by our 90-day money-back guarantee. We only ask that you give it a fair try: use KOIRRA® daily for at least 30 days (a full jar), since gut support works through consistency. Still not happy after that? Contact us within 90 days with your order number and our team will sort out your refund.
Is KOIRRA® third-party tested?
Yes. Every batch is third-party tested for purity, potency, and contaminants before it ships. What's on the label is what's in the jar: organic fruiting-body turkey tail, 1 billion CFU probiotics, and nothing hidden behind a proprietary blend.
