Ask your breeder when her lines typically go into first heat. I spayed my girl at 18 months with her not having had a heat, my dogs breeder said 20-22 months was common for her dogs line. Other lines it may be as soon as 8 months. I personally would really want to wait at least a year because of the Addison's risk, but if it's going to stress you too much during chemo to worry about it I would just do the 6 mo. You can only do what you can do and the human comes first.
