Installing a dog fence can be complicated, but we help make it easier. The Stay and Play compact wireless fence is our smallest size wireless fence transmitter. It'll help keep your dog secure in his yard so he can enjoy safely playing off-leash or napping in the sunshine with minimal installation time and no need to dig up your yard. Skip burying wires or building a physical fence - just plug-in the transmitter indoors and set-up your new wireless dog fence in 1 to 2 hr. The circular, wireless boundary adjusts to fit yards up to 3/4 acre. An LCD display on-the transmitter shows you what diameter your pet's boundary area is set to. Our wireless fence offers the most accurate wireless fence experience. The LCD display also has warning indicators to let you know if there is an error with your dog's fence. Since this fence is wireless, you can take it with you wherever you and your excellent friend go. Pack it with you when you go camping or when you travel in your RV, place the transmitter indoors and make sure you have an outlet nearby. This kit includes 1 rechargeable receiver collar that has a tone only mode and five levels of static correction which you can adjust based on your pet's training response. With a little training (a lot of treats too) your dog can learn his new boundary area in just two weeks. If your pet does ever leave the boundary area, he won't be corrected when he enters the safe play area again. If you have more than one pet at home, you can purchase additional receiver collars so all your four-legged friends can safely play in the yard together. Your pet deserves the best. Trust PetSafe to keep your pet healthy, safe and happy.
