Female dogs (bitches) don't have menstrual cycles in the same way that women do. Bitches go through estrus, or go into heat, three times a year. It is during these times that they are receptive to mating and can become pregnant. The odor of female dogs in heat is designed to attract males and increase the chances of mating. You can reduce the smell of your bitch's genital area by purchasing "bitch's britches" and pads for her to wear during estrus. These are available commercially and also reduce staining of furniture, carpeting, etc.

Shetland Sheepdogs, like all dogs, do not technically have a menstrual period - this is a biological phenomenon restricted to humans and primates. However, dogs do have heat or estrus cycles in which they are fertile and receptive to male dogs. These cycles occur every 60 days or so and are generally less than a week in length. The first heat cycle generally happens at 6-8 months of age, which is why veterinarians recommend having your female dog spayed by 6 months ofage.
