Today Buster had to have an unplanned surgery. The night before Thanksgiving we found a bump on his left side. We took him to see the dr. that Friday, but they didn't think it was anything to worry about. Not only has it doubled in size since then, but it nows seems to bother Buster. We took him in today and the vet has no idea what it is. He removed it and will send it for a biopsy. We should know more by Friday. he said it wasn't a cist like he though, but some kind of tissue growth. We pray it's nothing serious. Buster looks so sad!
