About us

We are here and we are VetImmune®
Happier, healthier pets is our goal.

Who we are and what we do.

Our company was formed to offer unique and specialty products that help strengthen the immunity of our pets. We focus on immunity because it is the system that protects us and our pets against disease and allows us and our pets to live happier, healthier lives. And the first product we are delighted to offer is Polyprenyl Immunostimulant™, the first and only therapeutic manufactured by Sass & Sass, Inc. and used for signs associated with feline rhinotracheitis (herpes) virus infection. More products will come soon, and we will gladly assist you and your fur children. Welcome!

VetImmune® is the distributor of Polyprenyl Immunostimulant™, a therapeutic approved by the U.S. Department of Agriculture for reduction of severity of the disease caused by feline herpesvirus infection.
