Estrus in dogs typically lasts 2 to 4 weeks, with the most fertile period during the 7 to 10 days of the estrus stage. Monitoring is crucial for breeding or preventing unwanted pregnancies, and spaying or neutering is an option for those not planning to breed.
Estrus, also known as the heat cycle, in dogs typically lasts for about 2 to 4 weeks. However, this can vary among individual dogs and breeds. The cycle is divided into different stages: proestrus, estrus, diestrus, and anestrus. The most fertile period, when the dog is receptive to mating, occurs during the estrus stage, which usually lasts around 7 to 10 days. It's essential for dog owners to monitor their pets during this time if they want to prevent unwanted pregnancies or, alternatively, if they are planning for breeding. Spaying or neutering is also an option for those not intending to breed their dogs.
