To enable your dog to become accustomed to the collar probes on his neck eliminate the collar soon after each and every training session in the course of the first week. Right after that, eliminate the wireless dog fence collar every night for the next three weeks. Ultimately he will probably be able to wear the dog fence collar all the time, however it may perhaps take some time for him to develop a tolerance to the probes on the receiver. Clean both the probes along with the dogs neck every single evening for the very first 30 days.The training flags are there for two reasons. Very first, to give your dog a visual boundary and secondly to help you with the training process. The flags ought to be installed about 12″ to your yard side on the dog fence wire inside the ground. All the flags will stay inside the yard for about 30 days.
