Well, now its evening and she's back to hopping on 3 legs.
We took both our dogs for walks, and she walked like normal including running. Then she layed down for a nap, and woke up hopping/limping again.
I debated giving her a bath as I had wanted to today, but then decided to go for it. The warm water must've helped, because now she is running around in that famous "post-bath race".
So..... I just don't know. I'm worried. We'll see how she does tomorrow.
