From the brand

For over 30 years, we have been manufacturing products to ensure the superior quality of life our pets deserve.

After our rescue dog, Winston, was diagnosed with arthritis & hip dysplasia, we began researching alternative medicine while working with Dr. Pedro Rivera. After several months, we developed a natural joint formula that gave Winston a second chance at life.

And thus, VETCLASSICS was born.
