When Does a Dog Go Into First Heat?

Understanding the reproductive cycle of dogs is crucial for pet owners, particularly when it comes to the female dog’s first heat. Known as estrus, the first heat is a significant milestone in a dog’s life, and it is essential to be aware of the signs and know what to expect. In this article, we will discuss when a dog typically goes into her first heat and answer some frequently asked questions about the process.

A female dog usually goes into her first heat between six and twelve months of age, although this can vary depending on the breed and individual dog. Smaller breeds tend to experience their first heat earlier, while larger breeds may take longer. It is important to note that there are exceptions to this timeline, and some dogs may go into heat as early as four months or as late as two years.

During the first heat, the dog’s body undergoes hormonal changes preparing her for reproduction. The most noticeable sign is vaginal bleeding, which can last for about two to three weeks. Other signs include swollen vulva, increased urination, and behavior changes such as restlessness or increased affection. It is crucial to keep a close eye on a dog in heat as she will attract male dogs and may try to escape to find a mate.

Now, let’s address some frequently asked questions about a dog’s first heat:
