When do dogs go into heat?

The female dogs go into heat once or twice a month. During this period, she will howl, showing her “availability” to male dogs. The owners of female dogs that are in heat must be very careful, because they might run away easily. Even if you have a faithful dog that does not run often, during the heat periods, it is likely for the dog to run away. You can think about sterilizing the dog. In this case, the female dog will not feel the natural feeling of mating, and she will not have the same “symptoms”. Moreover, she will not spread the common smells that alert the male dogs.
