I was very apprehensive last May when my 14 year old dalmatian, Cassie, had to have an infected cyst removed from the side of her jowel. We thought it was a fatty tumor all that time until it burst. She felt so much better when we got it out. I totally understand where you are coming from about putting her under. Cassie did great, but I was very worried. You have to do what you think best for Sasha. Hope she feels better soon.
