SportDog / PetSafe Fence System Keep your dog on your property and safe with this SportDOG - PetSafe Fence. Simply bury or lay the wire to form an enclosure, then plug the transmitter into a standard outlet. A lightweight, waterproof collar receiver gives your dog one of five levels of correction, with a warning tone then vibration before the correction when the boundary is reached. After a few short training sessions, your dog will remain within the encompassed area. This system includes 1, 000' of 20 gauge boundary wire, 100 training flags, 100% water proof receiver collar, and transmitter - this kit is enough to cover 1.4 acres. By purchasing additional wire and flags, you can expand the containment area up to 100 acres. And you can contain multiple dogs by purchasing additional receiver collars sold below. The SportDog receiver collar has an anti-linger feature that prevents your dog from standing in the warning zone and depleting the battery. A low-battery indicator on the receiver collar and a wire-break alarm on the transmitter give you peace of mind the system is up and running 24/7. You can customize the level of correction to match your dog's temperament, and the adjustable collar allows you to create a perfect fit for your dog. This system is for dogs from 30 pounds and up.

The wire sends a signal to a receiver worn on your dogs collar. The receiver features advanced technology that includes visual and audio alarms to warn you if there's a problem. With a PetSafe electric dog fence your dog can not only use the back yard, it can be in the front yard safe from traffic on the streets. Dogs are nosey animals and hate being stuck in the back yard where they can't see what's going on. A Petsafe electric dog fence changes all that. When they are in the back, every sound they hear they think may be you, thus building up a lot of frustration. Electric dog fencing by PetSafe allows your dog to go to the front yard and satisfy his curiosity, making your dog more calm. The front yard offers your dog entertainment and stimulation. He gets to see the mail man, the UPS truck, the trash men (their favorite), the school bus, and other things of interest including you, when you arrive home. You can create "Off Limits" areas with electric dog fencing, such as a pool or garden area. You can have your front yard separate from the back yard. If your dog runs out your open front door, he is still contained. PetSafe has a electric dog fence for every yard & budget. Try our discount PetSafe electric dog fence today.
