I worked with Nala today to acclimate her to a new wireless electronic fence. The system we have had in place for several years depends on a buried wire which defines her permitted roaming area. After the wire broke for what must be the tenth time we decided to investigate a wireless version. The technology has progressed substantially since I last looked at these systems. We are evaluating a product which uses a bidirectional Wi-Fi link between base and collar which allows us to know how far she is from the house at any time and also can monitor the condition of the collar battery remotely. The only downside of this approach is that the containment area must be circular. We found a transmitter location in the house which results in an optimal field. Now the trick is to retrain Nala from her old boundaries to the new ones.
