Bleeding during canine estrus: Duration and necessary care

Heat in dogs is a natural process that is part of their reproductive cycle. One of the most notable characteristics of this period is bleeding, which can be a concern for many pet owners. In this article, we will explore in detail the duration of bleeding during canine estrus and the care needed to keep our dog healthy and comfortable during this time.

Bleeding during canine estrus: What is it and why does it occur?

Bleeding in a dog in heat is a visible sign that she has entered her fertile phase. This process is similar to the menstrual cycle in females, although with some important differences. Bleeding occurs due to hormonal changes that prepare the bitch's body for a possible pregnancy.

During this phase, the lining of the uterus thickens and becomes more vascularized, resulting in blood flowing out through the vulva. It is important to understand that this bleeding is not exactly the same as human menstruation, as it occurs at the beginning of the fertile cycle rather than at the end.

Typical duration of bleeding in female dogs

The duration of bleeding in a dog in heat can vary, but generally lasts between 7 and 10 days. However, it is crucial to keep in mind that each bitch is unique and may experience variations in the duration of her bleeding. Some factors that can influence the duration include:

• Breed: Small breed dogs tend to have shorter cycles than large breeds.

• Age: Young dogs may have irregular cycles in their first estrus.

• General health: Health problems can affect cycle length and regularity.

It is important to remember that the dog's fertility period is not limited to just the days of visible bleeding. In fact, the dog may be receptive to males and become pregnant even after the bleeding has decreased or stopped.

Phases of the canine estrous cycle

To better understand the process of estrus, it is useful to know the four main phases of the canine estrous cycle:

• Proestrus: This is the initial phase, lasting approximately 9 days. It is during this stage that bleeding is observed. The bitch can attract males, but is not yet ready to mate.

• Estrous: This is the “true estrus” phase, which lasts about 9 days. Bleeding decreases and the bitch is receptive to males. This is the period of greatest fertility.

• In-estrus: This phase lasts approximately 2 months. If the bitch has become pregnant, it is during this time that gestation will develop.

Anestrus: This is the period of sexual inactivity between cycles, which can last from 4 to 5 months.

Necessary care during bleeding

During the bleeding period, it is essential to provide special care to our bitch to ensure her comfort and well-being. Some key aspects to consider are:

• Hygiene: Keeping the bitch clean is crucial. It may be necessary to gently wipe the genital area with unscented wet wipes or a damp cloth several times a day.

• Home protection: To avoid stains, you can use special diapers for dogs in heat or place towels in the areas where your dog usually rests.

• Exercise: Keep going for walks, but avoid places frequented by other dogs to prevent unwanted attention from males.

• Diet and water: Make sure your dog has access to fresh water at all times and keep her diet regular.

• Attention and affection: Your dog may feel more sensitive or anxious during this period. Give her extra attention and affection to help her feel comfortable.

Hygiene and cleaning of the dog in heat

Hygiene is a crucial aspect during your dog's heat. Here are some specific tips:

• Gentle baths: If it is necessary to bathe your dog, do so with lukewarm water and a mild shampoo. Avoid frequent baths that may irritate her skin.

• Local cleaning: Gently clean the genital area using wet pet wipes or a soft cloth dampened with warm water.

• Diapers for bitches: Consider using special diapers for bitches in heat. Be sure to change them regularly to prevent irritation or infection.

• Maintaining the environment: Regularly clean the areas where your dog rests to maintain a hygienic environment.

Behavioral changes in dogs during oestrus

During heat, it is common to observe changes in your dog's behavior. These may include:

• Increased restlessness: Your dog may be more nervous or agitated than usual.

• Increased affection: Some dogs seek more attention and affection from their owners during this period.

• Changes in appetite: There may be variations in appetite, either increased or decreased.

• Territorial marking: Your dog may urinate more frequently to mark her territory.

• Attraction to males: It is natural for your dog to show interest in male dogs during this time.

It is important to be patient and understanding with these changes, as they are a natural response to the hormonal changes your dog is experiencing.

How to avoid unwanted pregnancy in dogs in estrus

If you do not want your dog to become pregnant, it is crucial to take precautions during her heat period. Some preventive measures include:

• Constant supervision: Keep your dog under close supervision, especially during walks.

• Separation from males: Avoid contact with male dogs during the entire estrus period, not just during visible bleeding.

• Controlled walks: Use a short leash during walks and avoid areas frequented by other dogs.

• Consider sterilization: Spaying is a permanent solution to prevent unwanted pregnancies and may have health benefits for your dog.

• Veterinary consultation: Talk to your veterinarian about birth control options, such as birth control pills for female dogs.

In conclusion, bleeding during canine estrus is a natural process that requires special attention and care. Understanding the typical duration of bleeding, the phases of the estrous cycle and associated behavioral changes will help you provide the best possible care for your dog during this time. Remember to always consult with your veterinarian if you have specific questions or concerns about your dog's estrus.
