Just got a call from the vet.the cancer fluid has spread to her groin,the vet said that even with the amputation,that there was a 95% chance that the cancer would return in six months,I did not feel right about putting her throught the pain and recovery to have her be in pain in that short amount of time.She was asleep on the table when the vet called us,so we went ahead and let her sleep.at least she can chase lizzards as long as she wants,and eat all she wants,and never have to worry about anything ever again.....REST IN PEACE FAITH DOG WE LOVE YOU VERY VERY MUCH.
