LOL! Is this a song? I think the chorus is "And the dogs, they went a-running..."
If they've figured out climbing, you're going to have to either add electricity or move to an addition to the fence. Not barb-wire (that's too extreme), but some kind of a lip on top so that when they climb up, they get to the top and can't go any higher.
I had a dog (cockapoo) years ago who learned how to climb... the baby gate that we used to keep him in the basement. Came home one day and he greeted us at the door. Put him back in the basement, got out of site, and watched him climb.
He actually made us re-define our fence in the back yard. Any hole that was three inches in diameter was enough for him to take off through. We built an extension onto the gate, and buried a plastic barrier at the bottom of the fence (because he'd dig his way under).
Hmmm... I'm probably not helping. Don't let them read this [img]smile.gif[/img]
Might be time for invisible fencing... but with how many collars?
