Limping is a sign of pain in dogs, so yes Allegra is in pain if she is limping. I would recommend having a bone biopsy done. There is a possibility that she is suffering from an osteosarcoma (bone cancer), and a biopsy is a logical next step. Dogs are very good at hiding pain and oftentimes don't show how painful they truly are until much further along in their illness. I do recommend having this bone biopsy done.
