The duration of the first heat cycle in medium-sized dogs like Beagles can vary slightly but generally follows a specific pattern. The first stage of the heat cycle is known as proestrus, during which the dog's body prepares for ovulation. This phase typically lasts about 9 days, although it can range from 5 to 14 days depending on the individual dog and its overall health.

During proestrus, the female Beagle may experience some behavioral changes such as increased affection towards humans, restlessness, and a swollen vulva. However, she is not yet receptive to males during this stage. The next phase, estrus, marks the period when the dog is fertile and most likely to mate. This phase usually lasts around 9 days but can range from 5 to 14 days as well.

The final stage of the heat cycle is known as diestrus, which occurs after the dog has ceased being receptive to males. Diestrus typically lasts about 90 days, during which any potential pregnancy should be evident. If no pregnancy occurs, the dog will enter anestrus, a period of sexual quiescence that can vary greatly in duration but generally lasts from 4 to 12 months before the next heat cycle begins.

In summary, the first heat cycle in medium-sized dogs like Beagles typically consists of proestrus lasting about 9 days, estrus also lasting approximately 9 days, and diestrus lasting around 90 days. Understanding these stages is crucial for responsible pet ownership and potential breeding considerations.
