It doesn't seem that long ago that the knuckle dawg mutant was able to join his little bro on the deck railing. NOW, well I don't even think the deck railing would be wide enough for just one of his mutant paws. Just thought I'd share this.....when we first brought the knuckle dawg home he would get up on the deck railing with shovel and bond with him. That was 2 1/2 years ago. Oh, and the top of the deck railing is a good 12ft off the ground. It used to scare me when he'd get up there but he was even able to turn completely around with no problems.
