TOD:
The beloved dog of my childhood was Cindy, a cairn terrier who looked just like Toto. We were all destroyed when she finally died of cancer.
We still had her son, Duffy, who we turned into a neurotic dog, as children do. While we had him, my mom, who made all the pet decisions, decided she wanted another dog.
When she got our third dog, a St. Bernard named Gretchen, Duffy started running off to other houses, especially a house with a dachsund, which I guess made him feel like a big dog again. He was eventually killed by a pack of wild dogs (we lived in the mountains of Virginia) in the schoolyard where my mother taught, so she saw it all happen.
When I was in college, it was discovered that Gretchen had heart worms, and the treatment would be very expensive. So my mother had the vet put her down before anyone could object or even knew of her condition. This led my father into a deep depression that lasted for a long time, because he loved that dog very much.
Is it any wonder that as an adult I am now a cat person?
