Well shucks man, you'd be napping too if you had to chase a ball all day.
Seriously this dog has a great life. I've got a Golden Retriever who is either 15 or 17, papers conflict. Toby would prefer to lay around then run around. He's been that way since we got him from the local Retriever Rescue group. He doesn't see too well and doesn't get around like he used to but he is nonetheless a big part of the family, just a little more quietly now.
