Bridget:
Carina also had two fatty cysts removed. The last one was in her back and the size of a golf ball. It got so big because the vet told me not to worry about it, she knew it was not a tumor. Finally, she had to have surgery last Spring because I didn't want to see that bump in her back any longer. It was indeed a fatty tissue cyst. It's very common in some dogs, but the best thing is to consult with your vet. Hope that's all that is wrong with Daisy. Give her a hug from us
