Little dogs rejoice! We’ve catered Little Dog In-Ground Fence™ for your petite pal’s safety. It starts with our smallest waterproof receiver collar, specially designed for greater comfort. The reflective strip on the collar helps you find your small dog at night, so outside playtime doesn’t have to end when the sun goes down! To set up the system, you’ll establish the yard boundaries with underground wiring. Training your best furry friend to stay within those boundaries is a snap. No more straying. No more worrying. Just big freedom for those little paws.
