About Us

The PORTA-GRAZER™ is designed to replicate as close as possible a natural grazing environment for your confined equines by slowing down feed intake while simulating head down grazing behavior. The result is better physical as well as mental health for the horse.

We also knew it needed to be user-friendly while at the same time safe for the horse with no locks, latches, or hardware to fool with. It is perfect for at home or when traveling…no mess, no wasted feed, and no unsanitary conditions with the PORTA-GRAZER™. My goal is to contribute to better equine health as well as saving money for the owner.

We take great pride in our company, our commitment to customer service and in the products we sell. Our online store is designed to provide you with a safe and secure environment to browse our product catalog.
