Nutramax Laboratories files lawsuit against Zesty Paws

Nutramax files lawsuit against Zesty Paws.

Nutramax Laboratories recently brought legal action against Zesty Paws and its Hong Kong-based owner, H&H Group(1). The action is for false advertising regarding the ingredients, quality, third-party rankings and recommendations, and market performance of its products, as well as for making false or misleading comparisons to Nutramax’s DASUQUIN products.

Third-party testing of Zesty Paws’ products indicates that at least some of its products contain inconsistent, and sometimes undetectable, amounts of key active ingredients, and in some instances, contaminants, including E. coli and high aerobic microbial counts.

For more than 30 years, Nutramax has placed its valued customers first. It is committed to providing innovative products that are backed by science and held to the highest quality standards.
