Oh, yeah, that's another point. How big is she? Large dog spays are more difficult when the female is in heat because everything kinda fills up with blood, but if her heat's done with by now, or if she's small, it shouldn't be an issue.
You can probably find a lot of stuff about how spaying is good for the health of your dog. Can't get ovarian or uterine cancer if you don't have ovaries or a uterus! It also prevents this nasty condition called pyometra, which I'll let you google for yourself if you want. Plus, heats are hard on a dog. Spayed dogs, especially ones spayed before their first heat, live longer.

But many of us defer to the advice of our vets on many issues, after all, they are meant to be the experts, however if you ask multiple vets the best way to treat an illness or the best way to dress a wound or the best diet to feed your dog you will likely get multiple answers. That doesn't make them all right or all wrong, but as pet owners we must do our best to take care of our animals with the information we have available.
