How Often Do Female Dogs Go Into Heat?

Understanding Your Dog’s Heat Cycle

As a caregiver, you are the primary source of care for your female dog, and understanding her heat cycle is vital. It’s a natural process that deserves your attention and understanding. The frequency of a dog’s heat cycle can vary greatly depending on her age, breed, and individual health.

Typically, most female dogs experience their first heat cycle when they are between six months to a year old. From then on, the general rule is that dogs go into heat approximately twice a year, or every six months. However, smaller breeds may go into heat more frequently, as often as 3-4 times a year, while larger breeds might only cycle once a year.

Knowing when your dog is in heat can help you handle the situation better. You’ll notice several signs:

  1. Swelling of the vulva
