In early 2000, the founder Matt Koss discovered that his dog, Luna, was displaying early signs of renal failure. After exhausting all other methods, Matt took the advice of a holistic veterinarian who recommended switching Luna to a diet based on bones and raw food (also known as BARF or Biologically Appropriate Raw Food), which mimics how an animal would consume food in the wild.

With a renewed sense of hope, Matt created his own species appropriate pet food for Luna. After a short time on the new raw diet, not only did her appetite drastically improve, but she also showed an increase in energy and overall happiness. After seeing the powerful results of raw feeding firsthand, Matt set out to bring Primal to market so that other pets could enjoy a happier, healthier, more vibrant life.
