I'm not sure if you can see the depth of this hole that the dogs have dug...when Penny is at the bottom digging, you can only see her little nubbin'. Penny & Lola have a little system going. Penny gets deep in the hole & kicks the dirt out...and Lola is right behind her moving that dirt so it doesn't go back into the hole.
This was their designated dig spot, but it 's gotten so deep we're (aka Scotty) gonna have to fill it in so it doesn't cause foundation problems.
The girls also search for treasures in the ferns...
