Female dogs can go into season as early as six months in most breeds.
Well, it's not referred to as a "period" in dogs. Dogs "come into heat" are "in season" or "in estrus". Unlike in humans, this is when she can become pregnant and the only time she is interested in mating (and males are interested in her). Here is some info about the reproductive cycle in dogs:
The age a female first comes into estrus is variable. Can be as early as 6 months, as late as 2 years. (Though that's not common.) It happens roughly twice a year until she is spayed or dies.
