My 3 yr old Yorkie has just been diagnosed with Legg Perthes and medial patella luxation...the orthopedic vet says that there is no surgical intervention needed for the hip at this time as it already looks "smooth" but that the MPL needs to be corrected...surgery is set up for about 10 days from now...has anyone had experience with these 2 problems together? He was put on Novox for inflammation and pain which has made a huge difference but he can't stay on those type meds for the next 10-12 yrs
