As I understand it, the shock only lasts for 10 seconds, if the dog runs thru it. It does not reset till brought back into the zone, so there is no fear the dog cant come back wo a shock.
I guess some testing is in order.

Our situation had this issue and simply called the dog back into the 90' "ring of safety"and no problem. We did this to introduce the boundaries with the flags. Our dogs don't go past certain points with collars on. I used clippers on one dog to make sure the contacts were solid to the skin and full correction is made. Disadvantages to everything, we just minimized them to fit our needs.
Forgot to add that this is a portable system if you go camping or traveling and have access to a power source for the transmitter and a few flags for boundary reminders. Plan on using it this summer for this purpose.
Eddie, your going to have to share this story again in May at the Classic !
