Charlie is our Chocolate Lab, otherwise known as Grandpa.  He is 12, and has arthritis in his back legs, which is very common in Labradors.  He is a little on the chubby side, so he's forever on a diet.  He loves watermelon, cucumbers and cherry tomatoes.  He ate almost all of them out of the garden last year.  We couldn't keep him out : /

He does swim a lot, which is really good exercise for him.
