I'm sorry to hear of this with your cocker. By the principle of Occam's Razor that lump is painful and responsible for his lameness. Please have his vet thoroughly examine and X-ray that leg. Hard and painful lumps too often represent osteosarcoma (bone cancer) which should be readily apparent in X-rays. If his bones look good, the lump should be needle aspirated and the aspirate examined microscopically for its cell type. Once it's determined what the lump consists of, treatment can be more specific. I would expect surgical removal to be recommended as long as bone isn't involved.

Please respond with further questions or concerns if you wish.
