Understanding the Symptoms of a Female Dog in Heat

When a female dog enters her estrous cycle, commonly referred to as being "in heat," it's a time of significant changes in her behavior and physiology. Recognizing the symptoms is crucial for pet owners to ensure the well-being of their furry friend and to manage the situation appropriately. Here are some key symptoms to look out for if you suspect your female pet dog is in heat.

1. Swelling of the Vulva

One of the first signs that a female dog is in heat is the swelling of the vulva. This swelling is often accompanied by a discharge, which can vary in color from clear to pink or red. The vulva will gradually become more swollen as the heat cycle progresses, making it one of the most noticeable symptoms.

2. Changes in Behavior

During the estrous cycle, you may notice changes in your dog's behavior. She may become more affectionate and seek attention from you and other dogs. Conversely, she might also become more irritable and aggressive, especially if she is approached by male dogs. Some dogs may become more restless and exhibit signs of anxiety or nervousness.

3. Increased Nymphomania

Female dogs in heat often exhibit a strong interest in mating. This can be seen through behaviors such as raising her hindquarters, wagging her tail, and actively seeking out male dogs. This increased nymphomania is a natural part of the estrous cycle and is driven by hormonal changes.
