I too have followed this thread from the beginning and and am so sorry for your loss. Little charlie may not have belonged to you but he certainly thought of you and your pack as his own. Run free little man.

Oh so sorry to hear that, poor little Charlie and poor you, and his owners. Perhaps one of your dogs can go to visit when you visit, I know I would hate not to have dogs even as visitors.

I'm so sorry.  I've been following along and this is not the news I hoped to find.  Your heart must be broken.  My condolences to you and the wee Charlie's owners.

Very sad news for you after all that you have done for the poor lad x
