When is a Dog’s First Heat?

As a caregiver, understanding your puppy’s journey into adulthood is crucial. In this guide, we will delve into one of the most fundamental aspects of a female dog’s life cycle – their first heat.

Understanding Your Dog’s Reproductive Cycle

Female dogs typically experience their first heat between six and twenty-four months old. However, smaller breeds tend to mature faster, so they may start their cycle earlier than larger breeds.

This period, also known as the estrous cycle, includes four stages:

  1. Proestrus: This is the beginning of the heat cycle. It lasts about 9 days, and the dog may show signs like a swollen vulva and bloody discharge.
  2. Estrus: This is when the dog is fertile and lasts about 9 days. The dog may show signs like a change in discharge color and increased friendliness towards male dogs.
  3. Diestrus: This stage lasts about two months. The dog is no longer fertile.
  4. Anestrus: This is the resting stage, lasting about 15 weeks, before the cycle restarts.

Signs of Your Dog’s First Heat

Recognizing the signs of your dog’s first heat can help you provide the necessary care and attention. Here are the most common signs:

  • Swollen vulva
  • Bloody or straw-colored discharge
  • Increased urination
  • Changes in behavior, such as clinginess or aggression

How to Care for a Dog in Heat

During this time, your dog will need extra care and attention. Here are some tips:

  1. Keep her indoors: This prevents unwanted pregnancies and protects her from male dogs who may be aggressive.
  2. Provide a comfortable space: She may be uncomfortable, so provide soft bedding and keep her area clean.
  3. Watch her diet and exercise: She may eat less and may not have as much energy for exercise.
