Simon does that digging thing, too. It still keeps me from letting him nap up on our bed. I hope he grows out of it or at least takes it easier!
Funnily, we had to teach him to dig in the sand at the lake. He kept looking at us like we were silly creatures for even touching that stuff.
As far as furniture, we're doing the usual "put everything up high, not high enough, higher – do we care about this thing or should we give into that cute face?" And this puppy can JUMP! He can leap onto the kitchen counter from the floor without a running start. Egad.
