Hi! I have a 9yo female beagle, Lucy. In November 2008 she had an ugly growth removed from her mouth. It came back melanoma as the vet suspected. She was given 6 months to a year to live then. Well, a year has come and gone. In November 2009, we had a 2nd ugly growth removed from her mouth. Shortly after that surgery, I noticed that the lymph node on the left side of her throat was growing. The vet said this was the cancer spreading. The lymph node is about the size of a baseball now. Our vet feels like it might only be a few more months. She is a happy dog. She eats well and plays with her toys and loves to stand outside at night and catch bugs that gather around the garage lights. We don't want her to suffer. When will I know its time to let her go before she is in pain? Thanks for any and all replies.
