Jack turned fifteen years old today. We think he's pretty old now. Walks are slower & shorter. He often likes to sit & rest on these short walks. When he commences to lie down I remind him that we are on a "walk" not spending time in the back yard. Often when he is in the backyard he likes to just lie down & watch the birds & squirrels. He long ago gave up chasing anything but he certainly knows how to relax & take it easy.
