Great fence, beautiful view for handsome Baron. I know your boy will respect the boundary set up for him, the same way Dobies treat baby gates and X-pens inside the house.
However, our Spock did jump a baby gate for the first time last weekend when I was having one on one playtime with Eva playing tug (his favorite). It was my mistake for taunting him and should have had him outside.
I have no doubt if you were outside your fence, being attacked by a killer squirrel, Baron would scale it in an instant to save you!
