At Dirty Paws Botanicals, every batch we carry is third-party tested before it reaches you. No exceptions. The results below are from our most recent inventory, analyzed by Murray-Brown Laboratories, Inc. — an independent, accredited testing facility based in Northglenn, CO.

These COAs aren’t marketing. They’re the actual numbers. Every batch is screened for microbial contamination, heavy metals, and alkaloid content. If something doesn’t pass, it doesn’t ship. Simple as that.
