I took Beastley in for a "cold tail" and also mentioned he has been raising his right rear leg but we tell him to sit and then he walks normally. He felt his knee and did xrays and he said he had a luxating patella. He said I could get a second opinion with a orthopedic surgeon if we wanted but surgery with an orthopedic surgeon could cost upwards of $2500.00. OMG He said if it isn't corrected he could become lame and develop arthiritis. Has anyone had this type of surgery and what is the success rate. Is there any place to assist financially for surgeries such as these. Any suggestions would be appreciated.
