Well, my old dog had her last morning this morning.  We knew she wasn't well when she wouldn't eat and was having trouble moving around the kitchen.  A quick trip to the vet confirmed that the old girl had tumors all through her body and was on her last legs.  The vet said that putting her down humanely was the best option for her, so that's what we did.

She was a good dog, and in her older years she and I became much closer than when she was younger.  Apart from the last couple days she was always in good spirits, and would often do something we called "the happy Tina dance"... it involved her rolling about on the floor and kicking her legs happily while arching her back.  The last time I saw her do it was last week after I gave her a bath.  So I know she was happy pretty much right up to the end.

So long Tumblin' Tina... for 15 years you've been a faithful (if dimwitted) companion to us, and we will always love you.
