I am fostering a dog. A little Jack Russell mix named Sweetie, although depending on how big she is, we might call her Itty-Bitty. It's a long-ish story, but the short of it is that a friend of some friends knows of a family on some hard times - and their dog needs a home to stay in for the interim. I figured I could handle that, as I'm already used to a small dog.
My hope is that she gets along with the cohabitational pets.
Yes, I realize that these foster situations turn into "forever homes". We'll see. Even if it turns out to be a pain in the ass, it feels like the right thing to do.
