We recommend the PetSafe Ultralight Dog Fence Collar for dogs that are 5 pounds or more and are easy or average to train. The PetSafe Ultralight Dog Fence Collar comes complete with nylon collar, batteries and short probes for short hair dogs and long probes for long hair dogs. It is compatible with all PetSafe brand underground fences and Radio Fence and Pet Guardian Underground Pet Containment Systems.  Battery Included. We recommend you get extra batteries with your order. Initial system set up and pet training will create more drain on the batteries than normal.  Typically the batteries included with the receiver will need to be replaced after 30-60 days.  Battery life under normal usage averages 4-6 months.
