Didn't you know your dog was in heat? usually a groomer will not take a dog which is in heat. If you didn't know (because I know not all dogs have visable bleeding) your groomer would have realised when the intact males were pestering her.
Either way I think you need to take your girl to a vet, breeding dogs is more complicated then you may think and I dont think it is worth risking your girls life for.
