More: My fishing partner Sam is 13 years young and on 11/3/2020 she had to have her right front leg amputated due to osteosarcoma. It started with a limp and was diagnosed as arthritis with no x-rays taken, which is very common. Two weeks later she was dragging her paw and x-rays confirmed osteosarcoma. This girl loves any outdoor activity, but fishing is her favorite. She knows there’s a fish on before we do. We are working towards kicking this nasty diseases butt! If your dog develops a limp please have it x-rayed as this is a very aggressive cancer and the sooner you catch it the better. FIsh On and TIght Lines
