I'm very sorry to hear that your Rottweiler has had such a tough go with illness all her life. Even with misdiagnosis, she is obviously been pulling through from your love and care and her strong will to be with you. Between these two factors, your and her love for each other, it may not be too late for her to have this procedure. The procedure does have a decent success rate, but that is dependent on underlying factors of the particular dog's health, strength and age.
However, since I cannot examine her and read through every medical test she has had, you are going to need to rely on the vet that you trust the most to guide you with this decision.
