Collapsible content

Harper, the English cream lab - she came to Kat as a puppy and inspired the desire for mushroom-based immune support for growing pups!

Harper's Story

These formulas are dedicated to my dog Harper, who inspired me to explore the benefits of mushrooms.

Harper was my very own quarantine puppy, an amazing distraction from all the chaos happening in the world. As the first developing dog I had taken care of in a while, she inspired me to deep-dive into helping her develop into the healthiest adult she could be. I learned that building a strong immune system was a key to long-term health, and went on a path to discover the power of mushrooms.

Tasty topper!

You know how one partner makes the dogs’ food one way and the other makes it their way? Well I add Harper’s Immunity topper to my dogs’ food after I mix in wet + dry food, and our pups gobble down their meals immediately. When I was out of town my husband made the food without the topper and the dogs just stared at their bowls until he sprinkled some on! They love it, and I love that it supports their immune system. We have a Doberman (Thor) and a Frenchie mix (Coco), and many Dobies have very sensitive stomachs. We have used Harper’s immunity topper since Thor was a pup and he has never dealt with a sensitive tummy. His coat is shiny and gorgeous! We will soon get the joint support topper as well!!
