How long does the first estrus last in Shepherd dogs? - in detail
The first estrus in Shepherd dogs, also known as the heat cycle, typically occurs between the ages of six months to two years, with most experiencing it around six to twelve months. This initial cycle can last anywhere from two to four weeks, though the duration may vary slightly depending on the individual dog. The estrus cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus. The proestrus phase marks the beginning, lasting about seven to ten days, during which the female dog may exhibit signs such as swelling of the vulva and a bloody discharge. This is followed by the estrus phase, which lasts approximately five to nine days and is the period when the dog is fertile and receptive to mating. The diestrus phase follows, lasting around two months, during which the dog’s body returns to its normal state if pregnancy does not occur. Finally, the anestrus phase is a period of inactivity in the reproductive cycle, lasting several months. It is important for owners to monitor their Shepherd dogs closely during this time, as proper care and attention can help manage any discomfort or behavioral changes associated with the estrus cycle.
