bad knee

Hi, I've read this column enough to know that you don't give medical advice, how about advice on dealing with a medical condition? Snoopy, our 3 year old female, would SOMETIMES limp and yelp in pain, and the next moment run and jump as usual. After tests and xrays, it was confirmed that Snoop has a torn ligament in her rear knee. Prognosis: It may heal itself with a month's rest, if not she will require surgury.

We are trying everything to keep her calm: crating her when we are gone (she was crate trtained, but we haven't used it in two years), picking her up to put her on the bed, carrying her outside (so she doesn't take her customary leap out the back door - over the mat and down 5 steps!). Despite all, we cannot get her to calm down and are concerned that she may have to have surgery. Any tips? Thank you.
