Has anyone else had a problem with their puppies realizing if they run really fast or leap into the garden they can avoid repeated zaps from the electric fence? Once they are in they run around like it's the Indy 500 Speedway and destroy my plants. We are thinking of adding more wire and snaking it through the beds so they would not have a "safe zone" . Any thoughts? I am still going to mke them their own garden but have not had the time to plan it out yet. Some days they could try the patience of a saint!!!
