Just recieved a call from the vet. Because the symptoms for HOD were not all present,(no fever, swelling, heat in the joints) and the changes in the long bones were so mild that they decided to send the xrays to a radiologist that specializes in growth disorders. Upon his recommendation they have reversed their diagnosis of HOD. They now say that it was an unusually strong growth spurt, and are no longer recommending euthinasia. All of the research and information that so many kind people have sent to me, has helped me make several decisions. First he will come off of the rimadyl as soon as possible, and I am going to try MSM which is an animal nutrient anti inflamitory for stiff joints that has been around and in use for about 20 years, and also glucosemine, and try to cut the protien down in his diet to 21-24%. I will also be seeking another vet.
Thank you all for your support and well wishes, and I appreciate everyone that sent information and prayers.
