You do not need to wait. Those firmware updates (like Nokia's Lumia Cyan update) and carrier updates are separate from the Windows Phone 8.1 Update 1 RTM update that is now available.
A Puppy's Life to Dog-dom. Weeks 1 and 2. These weeks are very quiet in that the puppies can not see or hear for the first 10 to 15 days, they can not regulate their own body temperature - they are totally dependent on their dam and their environment for warmth, nutrition and stimulation.
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.
