We are having exactly the same problem with Winnie! She started limping a week ago today on her right front leg. We took her to the vet, who found a bruise in between her paw pads. She is not limping as badly now, but she still does limp, especially when she first gets up from a nap. Also, it's almost impossible to keep her from jumping up and down off of the couch and bed. We never crate her either, unless we leave the house, which is rare. At times she doesn't limp at all. I'm going to give her a couple more days and take her for an xRay if it's not cleared up, because it seems like a bruise should have cleared up by now. Keep us posted and I'll do the same!
