Our lovely labrador (who we got off a MNer last year) has developed mammary tumours. The vet said to spay her and have the mammary strips done will cost in the region of £500. I don't care about the cost, at the end of the day, I would sell everything I own to pay for it for her. BUT the vet has said that there are no guarantees that the mammary tumours wouldn't come back. She is an old dog. 9-10 years (ish), so too old to insure as well. I am really concerned about putting her through such a major op at her age. I don't want them to operate on her to lose her on the table or she gets ill afterwards. The tumours can still come back afterwards if she has the op. She seems ok in herself at the moment. They don't know if the tumours are canerous or not. They might not be, and she could go on for the rest of her life with them, or they could be bad and affect her quite quickly. Oh I don't know what to do. I only took her in for her booster injection
