My dog's limping for a month, not broken. Why does he tuck his leg?
Limping can be caused by several different problems - if x-rays didn't show a fracture, then it is likely that Bentley has some type of soft-tissue injury causing him to limp. One of the most common injuries like this that we see in dogs is a torn cranial cruciate ligament (CCL) - this is the same ligament that human athletes sometimes injure, called the ACL in humans. This ligament is responsible for stabilizing the knee joint when the dog walks, so if it is torn it causes significant lameness that does not improve with rest and pain medication. Other possible causes of limping for over a month would be a torn muscle, or a torn tendon or ligament in another part of the leg. Unfortunately, these injuries will not show up on x-rays. If your veterinarian doesn't have any other suggestions for further testing (such as a sedated orthopedic exam to check joint stability), then I would recommend asking for a referral to an orthopedic specialist. Bentley may need an MRI or other advanced imaging to diagnose the problem.
