Lady lifts her right leg slightly when she pees. I think she does it so she won't pee on her foot.
Yes, please get your girl spayed before her first heat. You can basically eliminate her chance of getting mammary cancer later on.
The risk of malignant mammary tumors in dogs spayed prior to their first heat is 0.05%. It is 8% for dog spayed after one heat, and 26% in dogs spayed after their second heat. http://www.peteducation.com/article....&articleid=460
