It took Happy Herd two years to find a farm that collected urine in a manner that was acceptable to the Happy Herd Brand. From the void to the bottle is the most crucial factor when handling urine and to assure the urine is bottled contaminant free. With the medical laboratory experience that is the foundation of the science and studies of the Happy Herd Brand, we are able to do just that. Contaminants are the number one contributing factor that causes urine breakdown. Hence, the ammonia odor. Every mature buck in the woods knows the difference. Happy Herd is the brand you can trust with every product we offer. If it’s not the best, you simply will not see it on our lineup of products. Guaranteed!!
