Yesterday, I was petting my Maddie and felt a lump on her belly. I immediately thought mammary cancer. I took her to the vet and they expressed clear fluid from her nipples. The vet said this was the weirdest thing and she has never seen anything like it. Surgery is scheduled for Monday to remove these masses but I am just curious if anyone else has encountered this? The masses will be biopsied so eventually I will have an answer. I have attached a picture. Oh and I should add she has been in diabetic remission for a year and a half now. Thanks!
