OK, thanks for the reply. When we see limping in the rear leg of a large breed dog, we usually are going to look towards the knee first, before the hip. It is common for large dogs to tear the cruciate ligaments in the knees. A partial tear can result in intermittent limping and pain, whereas a complete tear often results in a complete inability to bear any weight at all.

Usually this problem can be diagnosed with a combination of a detailed orthopedic physical examination, along with x-rays. If there's only a partial tear, then 4 to 6 weeks of rest (no off-leash exercise at all), and a prescription anti-inflammatory (safer than over the counter drugs), can be attempted. In cases of a severe partial tear or complete tear, surgery is usually needed.

If the knee is OK, then the hip is the next logical place to look. Hip dysplasia is common, but is difficult to manage, other than weight loss, glucosamine supplements, and, if truly severe, hip replacement surgery.
