I do feel for you. Both Roxy and TJ have luxating patellas in both rear legs. Roxy had surgery ($3000 - ortho specialist in Westbury, NY - Long Island), Roxy's right leg is luxating again, she will have surgery on 11/20/06 to futher stabilize that leg (another $600 - $800). TJ will have surgery next summer (that will be at least $3000)...
I didn't except this, but I wouldn't trade them for the world. They are my babies and I would provide anything they ever needed.
This must be very hard for you to decide, but only you can make that decision....
Even though my husband and I have spent and will spend thousands of dollars (that we never expected to) on TJ and Roxy, I am soooooooooo thankful that they came into our lives, b/c they could of gone to another home, where the family couldn't or even worse wouldn't provide the medical needed for them.
You can PM me anytime if you'd like to talk futher...
