How Can We Help?

A daily bacon-flavored powder for dogs. Every scoop combines 1,000mg of organic fruiting-body turkey tail mushroom with 1 billion CFU of live probiotics to support your dog's gut balance, normal immune response and everyday energy.‡ No fillers, no proprietary blends, and every batch is third-party tested.

Neither. KOIRRA® is a fine powder you stir into your dog's regular food. No pills to hide in cheese, no chews packed with binders: just one scoop over breakfast and it disappears with the meal.

One scoop a day, stirred into a meal. Each jar contains 30 servings, a full month of daily support for most dogs. The included scoop makes dosing effortless.

That's what the bacon flavor is for. Most dogs lick the bowl clean, picky eaters included. And if yours is the rare exception, you're covered by our 90-day money-back guarantee, so trying it is risk free.

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.

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.‡

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.

KOIRRA® is formulated for adult dogs of all sizes, and many of our customers are the parents of senior dogs. For puppies under one year, or if your dog has a specific health condition, we recommend checking with your veterinarian before starting any new supplement.‡

We ship internationally, including the United States, the United Kingdom, Canada, Australia, and New Zealand. Prices on our store automatically show in your local currency.

Orders are processed within 1–2 business days. After dispatch, US orders typically arrive within 3–7 business days. International orders can take longer depending on your location, the carrier, and customs. You'll receive a tracking link by email as soon as your order ships.

Use the tracking link in your shipping confirmation email, or visit our Track Your Order page and enter your order number. Tracking can take up to 48 hours to show its first update after dispatch.

First, check your tracking link: international deliveries in particular can take longer than expected, especially around customs checks or busy periods, and tracking sometimes pauses for a few days even though your package is still moving. If your tracking hasn't updated for more than 5 business days, contact us with your order number and we'll investigate with the carrier and make sure your order reaches you.

Subscribe and your dog's next jar ships automatically, so you never run out mid-routine. Subscribers lock in the lowest price per jar and shipping on subscription deliveries is on us. You stay in control: skip, pause, or cancel whenever you like.

Anytime, no questions asked and no cancellation fees. Email us at support@koirra.com from the email address on your order (or include your order number) and we'll take care of it. To avoid being charged for the next delivery, make sure to cancel before your upcoming renewal date.

Of course. If you have a few jars stacked up or you're going on holiday, just let us know and we'll skip your next delivery or adjust how often your refills arrive. Email support@koirra.com before your renewal date and we'll set it up.

Yes, your first subscription order is covered by the same 90-day guarantee as any other order, under the same conditions of consistent daily use. And since you can cancel anytime, there's nothing locking you in.

We stand behind KOIRRA®, so every order is covered for 90 days from the date of purchase. We ask one thing in return: give it a fair try. Gut support works through consistency, so use KOIRRA® daily for at least 30 days (a full jar) before deciding. If you've used it daily and you're still not happy with what you're seeing, contact us within 90 days with your order number and a short note about how you used it, and our team will sort out your refund.

If your order hasn't shipped yet, we can usually still change the address or cancel it. Reach out as soon as possible with your order number and we'll do our best. Once a package is on its way, we can no longer intercept it, but you're always covered by the 90-day guarantee.

Email us at support@koirra.com or use the contact form on our contact page. We aim to reply within one business day.
