Ziva my little min pin is going to be getting a 'partial' spay today. She will have the uterus/horns, & cervix removed, the ovaries will be left intact. After tons of research this is the method I feel most confident about after back & forth, research, talking to several vets etc. My dad has done only a couple of them in 40 years and the dogs didn't have problems. His concern is the possibility of mammary tumors later in life, but the research I am doing mammary tumors have many causes, hormones, diet, environment, vaccines etc, and since Ziva is naturally raised (well since 4 months on), I'm hoping that won't be a problem. I know of several people who have treated tumors homeopathically & they've resolved on their own as well. Anyways keep Ziva in your thoughts that all will go well with her surgery.
