How long does heat last for Labrador Retrievers? - in detail
The duration of heat in Labrador Retrievers can vary, but it typically lasts between 7 and 14 days. During this period, female Labradors experience several stages.
The initial stage is called proestrus, which usually lasts about 9 days. During this phase, the female dog shows signs of heat, such as swelling of the vulva and a slight bloody discharge. However, she is not receptive to mating during this time.
After proestrus, the female enters the estrus stage, also known as the standing heat. This phase lasts about 5 to 13 days on average, but it can be shorter or longer in some cases. During estrus, the female is receptive to mating and will allow a male dog to mount her. The vulva remains swollen, and there may still be some discharge.
Following estrus, the female enters the diestrus stage, which lasts for about 60 days if the female does not become pregnant. If pregnancy occurs, the diestrus phase continues until the end of gestation, around 58 to 72 days after mating. During diestrus, the vulva returns to its normal size, and any discharge ceases.
Understanding the duration of heat in Labrador Retrievers is crucial for breeders and pet owners to manage the female dog's health and prevent unwanted litters. It is essential to monitor the signs of each stage carefully and consult with a veterinarian if any concerns arise during the heat cycle.
