I came home tonight to find Gambit had died. Lets not discuss the details of the next hour or so because it was really kinda awful but despite being a little hysterical I managed to get him to the vets office. They were really great and sympathetic and non judgy that I wasn't entirely rational and took good care of his final needs.
Gambit was a good dog. He was smart and handsome and on at least one occasion (possibly two more) he and Sammy scared off a sketchy character from our old house.
He has nearly 14 and had a breathing problem that was beginning to effect his quality of life. I wish he hadn't died all alone like that but I'm glad it was fast and he was happy the last time I saw him alive.
Goodbye Gambit you will always be my handsome boy.
