It is much cheaper i nthe long run to soay, also will prolong her life and elimante the chance of a piometra which would need an emergency spay, and is quite pricey. There is a lot of info online with the benefits ofspaying.

Answer 2

The best thing to do is to spay her. Preferably before her first heat which normally occurs at around 6-8 months. This will greatly reduce her risk of an early death from mammary cancer, uterine cancer & infections, etc. She will be a healthier and longer lived dog so make an appointment with your Veterinarian to have her spayed and do not do it while she is in heat as her chances of bleeding are greatly increased at that time.

Answer 3

Keeping the females and the males apart, when you know the females are in heat, so they can't breed.

Or, getting the females spayed, and the males neutered.
