I am the bad neighbor. We just moved to a farm house about 15 miles from where we are building our own place. I use a radio controlled perimeter fence system with shock collars for my two Podencos. The older one stays within the limits of the system, but the younger one has run thru the system twice and taken off. We have since recalibrated the transmitter and collars and they seem to be working properly but when the dog took off, he was gone for many hours and I could hear him in the distance barking. The first time was about 10:30pm and he didn't come home till 3 am. The second time was in the early morning and he was gone till the afternoon. I could hear him barking in the distance and used google maps to figure out where the roads were that would get me to where he was. I didn't find him but he was waiting on the porch when I got back. He was completely torn up with cuts and abrasions and his eyes were very swollen from running thru tall grass and getting loads of pollen and debris in them.
That was enough for me. That was when I recalibrated the transmitter and collar. But the next day I stopped at Cabella's and bought a Garmin Alpha 100 GPS tracking/training collar and handheld. I have been training him on this and we put it on him regularly when he is outside. I don't want to lose my dog. I don't want him harassing anyone else's dogs or other animals and they would be completely justified in shooting him if he was.
