Zamzows

Zamzows is an Idaho lawn, garden, and pet business with its own line of dog and cat foods, not just another retailer reselling national pet brands. The company traces its story to the Zamzow family in the Treasure Valley, with roots going back to the 1930s and a current headquarters in Nampa.

The ownership trail is clear enough to list. Zamzows' homepage describes the company as family owned and operated since 1933. Its about page tells the longer Zamzow family story, beginning with August and Carl Zamzow in Meridian and the family business that grew from there. The company's LinkedIn profile lists Zamzows Inc. as privately held, based in Nampa, and family-owned and operated. We found no acquisition record, corporate parent, or match in the corporate-parent exclusion list.

For Clean Directory, the interesting part is the proprietary pet line. Zamzows sells its own dog foods, including Grandma Z's formulas and Dr. Jim Z Idaho Trout and Potato Fermented, alongside other pet products and local store support. That matters because pet food can be opaque: private labels, contract manufacturing, vague ingredient language, and little connection between the people selling the food and the customers feeding it.

The company does not publish every manufacturing detail a pet-food purist would want. That is a fair limitation. What it does provide is a named family business, a long operating history, a real retail presence, and product pages tied to the Zamzows name rather than a shell label.

Zamzows is still a regional business, so shoppers outside Idaho should check shipping and availability by product. The brand is strongest for people who want a family-run pet supplier with a long local history and a narrower house-brand food line instead of a faceless marketplace.

This is not a boutique raw-food startup. It is a durable Idaho family company with deep pet and garden retail experience, a visible store footprint, and enough ownership transparency to make the cut.
