Born from a family’s loss of a German Shepherd, Dog Guard has made electronic pet-containment systems in Troy, New York, since 1988. This second-generation family business uses North American-made components and performs final assembly and testing in-house, then supports installations and pet training through a network of locally owned Dog Guard Pros across the country. Its FreedomPro system is designed for precise underground boundaries, including small yards and tight spaces, with a rechargeable collar offering up to 30 days of battery life.
