Thank you, everyone, for your kind words.
I'll get some new pictures of Charlie posted, as soon as I can.
Charlie has been slowing down the last year or two. When we do our walk down the street, he often stops (and doesn't want to contine) on our way back.
I often pick him up and carry him one or two houses, before putting him on the ground so we can continue the walk.
Also, especially when he gets up from sleeping, he has a noticable limp. I started him on a joint treatment, late last week, so I'm hoping he responds to the treatment. I believe it's Glucosamine (please pardon my spelling).
Otherwise, Charlie is doing fantastic. I figure in human years, he's around 59 to 63 years old (depending on how it is calculated), so I understand exactly what he is going through since I am in the same general age bracket .
Thanks again for the support. I am enjoying the "here and now" with him and feel blessed to have such a wonderful dog. Cavaliers are the best!
