Most Beagles stay in heat (active phase) for around 2-3 weeks. During this time, a female dog is prepared for mating and potential pregnancy but some precautions must be ensured. For instance, it is important for beagle owners to monitor their dogs for unwanted bleeding and take appropriate measures to prevent it.

Similarly, it is highly recommended to let your Beagle go through a few heat cycles before allowing them to mate. This is important because your female Beagle should be fully developed before pregnancy. Keep reading to know about the stages of a dog’s heat cycle and learn more about the duration for which beagles stay in the heat.

What Are The 4 Stages of a Dog in Heat?

The entire heat cycle of beagles is divided into four stages (proestrus, estrus, diestrus, and anestrus). Dog owners need to understand each of these phases to take appropriate measures and prevent complications. In addition to preventative care, you may need professional help in case some unusual symptoms appear. Let’s discuss each one of them in detail to ensure that you are well familiar with all the phases.

Proestrus

This phase usually lasts around 9 days. During this phase, the body of a female dog is prepared for mating (and potential pregnancy). This is when the dog’s vulva starts to swell, and she may exhibit behavioral changes such as increased affection or irritability. However, it should be kept in mind that the female is not yet receptive to mating during this stage.

Estrus

This is the active phase of the heat period during which the female beagle is receptive to mating. It usually lasts around 9 days but can range from 3-21 days. During this time, the vulva continues to swell, and the female may also exhibit signs of attraction to male dogs. This includes frequent urination and lifting of the tail.

Diestrus

This is the period of sexual inactivity and usually lasts around 2 months. It is characterized by a decrease in the female’s reproductive hormones. In case the dog became pregnant, diestrus is when the fetus(es) will develop. The body will also prepare itself for delivering the puppies during this stage.

Anestrus

This is the last stage of the heat cycle and can last around 3-4 months. During this phase, the female beagle will not exhibit any signs of sexual behavior. This stage is crucial for the female’s reproductive health because it allows her body to rest and recover.

How Long Does a Beagle Bleed in Heat?

A beagle typically bleeds or experiences discharge during the first stage of their heat cycle (proestrus). This bleeding can last anywhere from 5 to 14 days. However, the average duration of bleeding for Beagles is around 7 days.

The discharged blood can vary in color and consistency, ranging from light pink to dark red. Similarly, it will be accompanied by swelling of the vulva and you must observe your dog closely. This is because it is important to prevent any contact with male dogs to prevent unwanted breeding.

Once the proestrus stage is over, the discharge may decrease in amount. This is because the beagle will enter the estrus stage where she is receptive to mating.

As a beagle owner, it is important to be aware of the signs of your dog’s heat cycle. It is also important to take appropriate measures to prevent unwanted breeding during the heat cycle. For example, you should keep your Beagle indoors or on a leash during the inactive phases to prevent unwanted bleeding. Similarly, you may need to seek veterinary care to deal with any unusual symptoms or behaviors. Some of the most obvious and useful symptoms that indicate a dog is in heat are explained below.

Swollen Vulva

One of the most noticeable signs that your beagle is in heat is a swollen vulva. This may be accompanied by a discharge, which can range in color from light pink to dark red.

Increased Urination

Beagles in heat may urinate more frequently than usual. This is due to the hormonal changes that occur during the estrous cycle.

Changes in Behavior

During proestrus, the first stage of the heat cycle, your beagle may exhibit behavioral changes such as increased affection or irritability. During estrus, she may show more interest in male dogs and may lift her tail or urinate more frequently.

Changes in Appetite

Some beagles may experience changes in appetite during their heat cycle. This may be due to hormonal fluctuations or changes in behavior.

Excessive Licking

Beagles in heat may also lick their genitals more frequently than usual, which can be a sign of discomfort or irritation.

Restlessness

Beagles in heat may also appear more restless or anxious than usual. This may be due to hormonal changes or a desire to mate.

You should also be aware of the different stages of the heat cycle to better understand the needs and behavior of your dog. With proper care and attention, you can help ensure that your beagle stays healthy and happy throughout her heat cycle.
