Poor Diablo! I'm sorry to hear that he's having this problem. If I'm understanding you correctly, it sounds like he has a bone tumor of some kind affecting his femur - I'm assuming that this was diagnosed on x-ray, along with the physical exam. Statistically, by far the most common type of bone tumor in a dog of this age and breed is an aggressive cancer called osteosarcoma - it's best to confirm this with a biopsy if possible, but it can be very difficult to get a diagnostic sample of a bone tumor without special equipment. If you want to try and get a definite diagnosis, I would suggest asking for referral to a specialist who can take a full-thickness bone biopsy with special tools. If referral isn't something you want to pursue, I would recommend asking your vet for treatment recommendations at this point based on the presumptive diagnosis of osteosarcoma - this might include amputation of the affected leg, and/or palliative treatment with anti-inflammatories and pain medication to make him more comfortable.
