Been very many years since I have been on this forum due to TPLO with our first lab Tank (RIP). I am looking for any advice on this type of cancer. Our almost 13 year old lab Orson has received a detrrmination on a punch biopsy of this tumor in the rib area. I am wondering what to expect for life expectancy. At the present we feel any intervention will be not be a wise direction for him.
