Aw, poor Chamois! I'm glad to hear she's recovering well, though. My boxer girl has been there... She tore a ligament in her knee (pretty sure it was the ACL, but I could be wrong) when she was younger, 3 or 4 years old, and ended up developing arthritis at an early age for the trouble. She's still doing incredibly well these days, though, despite her arthritis--12 years old and still going strong.
