I just had to share this. My daughter's near 13 year old Lab has had a number of major health issues in the last 3 years, among them the loss of a cancerous leg 2 years ago and a cancerous spleen last November. But he's a fighter and as strong as a plow horse when I'm walking him, almost daily.
My daughter always makes him his annual Halloween Costumes and last year he was Bat Dog and this year he's a Pirate Dog. Too cute!
