PetSafe SportDOG® Add-A Dog® Collar

The SportDOG Contain + Train System combines an in-ground fence with a remote training system. But it only includes one collar receiver. For households with multiple dogs, this collar responds to the system's remote and In-ground fence transmitters so you can make sure each dog gets the same message. With this add-on collar, the Contain + Train system can be expanded to include up to three dogs in Training mode, and unlimited dogs in Containment mode. The collar receiver should not be worn for more than 12 consecutive hours. Reposition the collar every 1-2 hours so the contact points are not always rubbing the same spot on your dog's neck. Keep your dog comfortable by removing the receiver when he or she is safe indoors.
