Invisible fence Does anyone own an invisible fence for the backyard? Right now we have a fence but we are moving and fences are not allowed. There is a man made lake in back. He loves to run around in the yard here but won't be able to let him loose there and wonder if the transmitter on the collar is heavy. Do you keep it on them all the time? I wonder because he is an escape artist and runs out the door as soon as we open it a crack. Thanks |
