In-ground fences are a great option if you have a rectangular or uniquely-shaped yard. When you bury your boundary wire, you have the flexibility to fence in a customized area for your dog. Setting up an in-ground pet fence is a DIY project, so plan to install your new fence over a weekend. We’ve designed a rechargeable receiver collar with 8 levels of correction. Level 1 is a tone and vibration setting which is helpful for when you’re training your dog. The vibration level is also great for pets that are hard of hearing so they can enjoy safely playing outdoors too. Levels 2-8 are adjustable static correction that you can set based on your dog’s temperament. This system includes 2 collars, but you can add as many pets to this in-ground fence system as you need. Just purchase additional Classic In-Ground Fence™ receiver collars (sold separately) for every furry member of your family. This In-Ground Fence™ system comes with 500 feet of boundary wire which lets you secure up to a 1/3-acre yard. If your yard is larger, you can purchase more boundary wire (sold separately) to fence in up to 5 acres. The In-Ground Fence™ transmitter has an LCD screen which allows you to easily see the boundary distance setting, and if there are any wire breaks. And if your dog has a habit of getting into the kitchen trash can, or digging in the flower beds, the Classic In-Ground Fence™ receiver collar can help with that too. This collar is compatible with all our Pawz Away® Pet Barriers, so his collar can keep him safe in the yard when he’s playing outside and teach him off-limits areas inside. Your dog deserves a safe backyard to play in. Trust PetSafe® to keep your pet healthy, safe and happy.
