A found dog

An email from Cindy.

"While out walking this morning, a woman who lives at 224 Elm (I think I'm recalling the address correctly) came out of her house while a very friendly dog was barking at us in the yard. She said the dog showed up a few days ago. It's a female, the lady thinks she has greyhound in her. She is large, but thin, mostly white with some brown areas and a dark/brown black round patch on her side. The dog did not have a collar, but she put a red collar on it so she could take it for walks"

Anyone know who this dog might belong to?
