i would still recommend having her spayed...she will be healthier and happier. Their heat last 3 weeks and it can really get messy. She will need to wear diapers. If she did get out, she would most likely get raped.
I don't think you want that for your little girl.
Unless you are going into the breeding business, i think every dog should be neutered or spayed. There are so many stray dogs and cats and millions are put down every year in shelters.
Please leave the breeding to the professionals and get her spayed in a couple of months from now. She will be a much better pet temperment wise too.
You won't have to worry about her this way. Many boarding/grooming places won't take them if they aren't spayed or neutered as they don't want that liability. You can walk her and take her places without worry too. Good luck to you and your little girl.
