PetSafe In-Ground Fence Kit for Dogs - Electric Dog Fence & Underground Dog FenceMany dogs enjoy lounging, playing and running around outside, but pet parents may worry about their dog's safety. If you don't have a fence around your yard, or if your fence is not strong enough to contain your energetic pooch, your pet could accidentally wander off. The PetSafe In-Ground Fence Kit for Dogs is a safe and effective electric dog fence that provides gentle corrections to keep your dog within your property. Pet parents can gain great peace of mind by installing an underground dog fence. With an electric dog fence in place, your pup can run and play within the confines of your property, and you won't have to close off your yard with a big fence. The PetSafe In-Ground Fence Kit for Dogs is easy to install. Start by burying the boundary wire around your property. Next, make sure your dog is wearing the Deluxe UltraLight receiver collar. This waterproof collar communicates to the transmitter and buried boundary wire. When your dog comes close to the underground dog fence, a warning beep will sound. With proper training, the warning beep is enough of a deterrent for most dogs to stop and go back. Dogs that continue forward will receive a harmless static correction to remind them to stay in the area that you have established. The receiver collar includes four adjustable levels of static correction and a tone-only mode that will only beep. These different levels allow you to help your dog understand the boundaries established by the electric dog fence. With patient guidance from pet parents, most dogs adapt to the electric fence readily and will happily stay within the boundaries. The PetSafe In-Ground Fence Kit for Dogs includes additional measures to help your dog adapt to the underground dog fence. The kit comes with 50 boundary training flags that act as visual fence markers. Additional safety features include anti-linger prevention, which keeps your dog from staying within the warning zone (which could drain the transmitter's battery). A progressive run-through prevention system increases the correction if your dog tries to run through the boundary zone. All of the measures that come in the PetSafe In-Ground Fence Kit for Dogs can help your dog more quickly understand the boundary. This underground dog fence can work with multiple dogs if you have additional transmitters (sold separately). Additional wire can also be purchased to expand the boundary. Dogs adapt best to an electric dog fence with patient guidance and training from their pet parent. Please refer to the training materials included with this kit. Contact the manufacturer or a dog training expert if you have any questions or issues.
