I stopped at the dog pound yesterday. I saw about a dozen dogs that were very appealing, but one has stayed in my mind. She's a nine year old black lab. She was in the same "stall" that Gibby was in. She was quiet, sweet, and hopeful. She looked like a really good dog who has lost her family. She must not have been a stray, must have been turned in by her family, because there was information on her card - she's never bitten and she is house trained.
A nine year old wouldn't make much of a playmate for Gibby, but might make a good companion. My other labs lived to be sixteen and seventeen, so she might have some really good years left. I've been thinking maybe no one will adopt such an old dog.
I think I'll give the pound a call tomorrow and see if she is still there.
