Yup they LOVE to dig. Casper's dog run is completely tiled up with those cement tiles now too. At first it was just a few cement tiles, then he'd always find a new spot to dig. I finally got sick of the holes and just tiled up his whole area, lol.

If these dogs wanted to escape they would rather dig a hole than try to jump the fence.
