We just found out that our 12 yr old MH female Annie has a tumor the size of a baseball in her abdomen. My good friend and vet says if we do surgery to remove it we could maybe get her another 6 months, or we can keep her on pain meds and enjoy her as long as we can, he is thinking 2 to 3 weeks. She has a hard time getting up but once she is up she finds a bumper and just wants to retrieve. I dont know what to do. Any thoughts? Im a little worried at 12 she wouldnt make it through surgery. Any advice appreciated.
