Mija, my 8 month old yorkie only weighs 1 kg (2.2 lbs). Tomorrow morning she is scheduled for a sterilization operation. Mija almost died when i first got her and everything is starting to finaly go normally. I am worried about her because of her small size and past and I am not sure I should have the operation done. But on the other hand I have herd that not getting the operation can later on lead to cancer. I dont know what to do anymore
