We always recommend our clients research the available alternatives to the traditional spay and neuter to see if those options are right for them and their dogs. At Veterinary Village we offer an Ovary Sparing Spay and a Vasectomy as well as the traditional spaying and neutering.
Below is an article from Parsemus.org that gives some additional detail about the subject, and you can always find more information on our service pages Spay or Ovary Sparing Spay, and Neuter or Vasectomy, or our resource article The Spay and Neuter Controversy.
