Thanks for your support, Thief! I hesitated to write it, as I know it's a bit too honest, but it's true. The bottom line is that we love Silas even though he can be so obnoxious and selfish. He gets away with it more now as he's got a graying muzzle and I'm starting to worry my time with him is limited. I believe 13 is unusually old for big dogs, so I'm nervously checking on him each morning!
