Awww - poor Winston. Hope he recovers quickly and without complications. I understand that, although it sounds worse to break something, a broken bone is actually better than a lot of the other kinds of twists and tears you can have... since as long as the alignment is okay (which it sounds like it is) bones heal quite rapidly and consistently - or at least that is what everyone told me when I broke my ankle a few years ago!
Aw! Poor baby. That just breaks my heart! I'm glad to hear he's ok but I'm sorry that this is causing so much strain and worry for you and your family. You're in our thoughts and prayers. Squeegee sends Beagle kisses to Winston.
