Silly Dog Thinks he's a Puppy

Chico, our daughter's dog, has been with us this past week while they were in Costa Rica.  He is 15 1/2 years old and generally moves very slowly...unless there is a ball involved.  Then he forgets about his achy joints and takes off after it like a young dog.  I limit the times I throw the ball for him because I think he would keep running after it and then be too sore to move later.  The extra was taken right before I threw the ball.  I love the excitement in his face that we don't see often enough anymore.  Many thanks to Admirer for hosting Silly Saturdays!
