My grandmother was recently diagnosed with uterine cancer and is doing a daily radiation treatment. I don't know many of the details, sorry. To make it short: she was diagnosed with stage 1 uterine cancer, had a hysterectomy, and began radiation recently.Her dog, a tea cup chihuahua has stopped eating, stopped sitting with my grandmother and is just not her normal self. Is this because of the treatment? Should the dog be taken away from my grandmother while she is going through the treatment?
