I'm so sorry to hear your news. Definitely join the Circle of Greys group and get guidance as to treatment, meds, timeframes, etc. there. If you're not going to amputate, then good pain control with meds is critical for quality of life. You might want to send the x-rays to Dr. Couto at OSU for a second opinion to confirm the diagnosis. This is a very heartbreaking road to travel, however many of us have made the journey with our beloved hounds and can offer you support and a shoulder to cry on.
