How to know when a dog's heat starts? - in detail

To determine when your female dog is entering her heat cycle, also known as estrus, you should look for several signs and changes in her behavior. Understanding these indicators can help you prepare for the cycle and make informed decisions about breeding or preventing unwanted pregnancies.

1. Vaginal Discharge: One of the earliest and most noticeable signs that a dog is approaching heat is vaginal discharge. This discharge may be light in color, similar to blood or mucus, and can increase in volume as the cycle progresses. Keep an eye on your dog's vulva for any changes in appearance or secretions.

2. Swelling of the Vulva: As your dog enters heat, her vulva may swell and appear larger than usual. This swelling is caused by increased blood flow to the area as the body prepares for potential mating.

3. Behavioral Changes: Female dogs often exhibit behavioral changes during their heat cycle. These can include:

   • Increased urination to mark territory and attract males.
   • Restlessness or increased activity levels.
   • Excessive licking of the genital area due to discomfort.
   • Aggressiveness or irritability, especially towards other female dogs.
   • Decreased appetite in some cases.
   • Changes in sleeping patterns, such as restless sleep or difficulty settling down.

4. Attracting Male Dogs: During heat, female dogs release pheromones that attract male dogs. You may notice more male dogs showing interest in your dog, attempting to mount her, or following her around. This increased attention from males is a clear sign that she is in heat.

5. Physical Examination: If you are unsure about the signs, a veterinarian can perform a physical examination to confirm whether your dog is in heat. They may use a speculum to visualize the vaginal opening and assess the stage of the cycle.

6. Monitoring Temperature: Some owners monitor their dog's body temperature as a way to predict the onset of heat. A drop in body temperature, often by about 1-2 degrees Fahrenheit, can indicate that a dog is approaching her heat cycle. However, this method may not be reliable for all dogs and should be used in conjunction with other signs.

By being aware of these indicators, you can better anticipate when your female dog is entering her heat cycle. Proper care and precautions during this period will help ensure the health and well-being of both your dog and any potential offspring.
