About Us

hi…we’re KanavaRx, the makers of DiarRice

…and we’re here to support the lifelong bond between you and your dog.


We started our dog health and nutrition products in 2016.  We wanted our dog parents to have products that are developed by an actual practicing veterinarian based on what works from his experience seeing dogs every day for more than 25 years. And definitely not by some conglomerate chemical factory where profits dictate ingredients.

Since then, we have been making the purest, all-natural and most effective dog supplements that support and provide the best nutrition for your canine best friend.
