Canine Estrus Cycle. If your female dog isn't spayed, expect her to enter estrus approximately every six months. If she's a small breed, you might have to deal with the bloody, smelly discharge accompanying her heat cycle three times annually. Usually, a canine heat cycle lasts for two to three weeks, although the dog won't bleed that entire time. The initial discharge is fairly heavy, but it tapers off during a seven- to 10-day period. In addition to bleeding, a dog in season also urinates more frequently.
