4 year old NBRAN alumni Gunner has being using a Fi collar as part of his field training and his owner love it. Gunner is not a flight risk, but is an anxious dog that needs a job, which is to run and "hunt". His NBRAN foster and now Forever home trained him on an e-collar and now that he is being field trained wanted to add a collar with GPS abilities. The FI collar lets them choose a daily step goal which for Gunner is about 25,000 steps. In addition the app lets them see exactly where he goes and you can sign your dog up to see how they do compared to other dogs or breed specific. It's almost like having a face book page for your dog! Roberta & Bill R.
