Marty with Crinkles and Noodle

Our Story

In 2002 in Boulder, Colorado, Marty Grosjean adopted an adorable Lab mix named Crinkles who was suffering from several health issues. Conventional treatments only led to more unwanted side effects.

Marty knew the benefits of a natural lifestyle for himself, so he applied the same philosophy to his care for Crinkles. She started to thrive. She had more energy, bright eyes and a soft and shiny coat—the signs of a healthy and happy dog.

To help other pet parents, Marty launched an e-commerce website at onlynaturalpet.com in 2004 to provide access to people across the country seeking natural food, treats and wellness solutions for their dogs and cats. Due to popular demand, we soon began developing and selling our own products under the Only Natural Pet label. What began as a single flea & tick product has evolved into an innovative lifestyle brand offering food, treats, supplements and supplies with a focus on health, safety and sustainability.

Today, Only Natural Pet is still headquartered in Boulder and has grown into a team of pet health experts committed to researching, selecting and developing premium, natural pet products that support the health and happiness of your pets.
