Dr. Sue’s Recommended Tests for Osteosarcoma Diagnosis and Work up (pre-surgical biopsy optional)

As I discussed in the previous blog, the first sign of osteosarcoma (OSA) that a pet Guardian sees is usually limping, or refusing to put weight on the leg involved. This is because bone tumors hurt, especially when the bone bears weight — so your dog will be lame or will limp. You may see…
