SIL had an extremely strong willed GSHP. He would periodically approach the invisible fence line testing the collar. Once the battery/beeping diminished he would bust right through, but he was a Houdini in all things. Our last golden breached the fence twice. Both times the Princess was away for the night, and I think Dani went looking for her. I turned off the fence, and both times she returned early in the AM.
Lol. Whoever coined the term "dumb animals" was referring to their inability to articulate verbally, not their inability to problem-solve!
