Dogs love to play so we’ve designed a fence that gives them more space to run! With standard in-ground fences, your dog gets a correction before he steps over the buried wire. But with our YardMax® In-Ground Fence™, your dog won’t get a correction until after he steps over the buried wire, giving him the feeling that the correction area is infinite! With this fence you’ll get 500 ft of wire so you can fence in a 1/3-acre yard. If your yard is bigger, just purchase more wire to fence in up to 10 acres for your pet. You’ll also get 1 YardMax® Rechargeable In-Ground Fence™ Receiver Collar which has a tone-only mode and 5 levels of safe, static correction that you can adjust based on how your dog responds during training. With a little training, your dog will learn his new play area in just 2 weeks! If he ever tries to run through the boundary, the infinite correction area outside the boundary will help encourage your pet to turn and head back home. If you have more than 1 pet at home, purchase additional receiver collars so all of your pets can safely play in the yard together. Your pet deserves the best. Trust PetSafe® to keep your pet healthy, safe and happy.
