More pics - lol - sorry

My good boy's name is Bo. I rescued him when he was 7 months old and he is just the greatest dog. He gets up and follows me wherever I go. If I go into the backyard to get to the garage where the washer/dryer are, he always stands at the door to make sure I am ok. When I get up in the middle of the night, he always gets up with me. I feel bad because he is old, as much as I don't want to admit it...and I hate that he always gets up because I know that it must sometimes hurt his old bones. I don't see any signs of arthritis, but I figure that something must sometimes be achy for him. He always has this worried look on his face like he is in deep thought and he raises his eyebrows whenever he hears a noise. He is one of a kind, so loyal and I just hope that he has a few more good years in him. He is quirky, won't walk in the lawn sometimes, insists on walking down the driveway and on the curb to get to the car, so that his feet don't touch the lawn....yet, he has no trouble peeing in the grass later in the day. He just cracks me up constantly. I think the other two keep him young.
