Want the latest information on research regarding ovary-sparing spay? Check out this paper by Oregon State University veterinary student Megan Mattravers for an excellent overview.

One size doesn’t necessarily fit all (dogs, that is). Parsemus Foundation has been at the forefront of providing information on a variety of options for pet sterilization. Ovary-sparing spay, or “partial spay,” is a method of sterilizing your female dog without affecting hormones. The uterus is completely removed but the ovaries, which produce most of the female hormones, are left intact. It turns out that natural hormones provide protection against a number of diseases in at least some breeds of dogs.
