Izzy has Lp...we had her X-rays assessed by radiologist at the University of Guelph and the university of PA..the radiologist in Guelph recommended surgery..the radiologist. at uni of Pa recommended we wait and see how she managed...take supplements and have her build her leg muscles up by walking up hills of at least 45 degrees...and if we did go the surgery route to make sure it was by a board certified surgeon . We have been lucky , Izzys problem has never worsened..but If she does require the surgery we will have it done in Mexico by a board certified ortho surgeon for a 1/3 of the cost here and momma can have a nice vacation by the ocean .
