How long does heat last for Staffordshire Terriers? - in detail
The duration of estrus, or "heat," in Staffordshire Terriers can vary depending on several factors, including age, overall health, and individual genetics. On average, however, the estrous cycle in these dogs typically lasts about 18-21 days. This cycle is divided into four distinct phases: proestrus, estrus, diestrus, and anestrus.
The first phase, proestrus, usually lasts around 9 days. During this time, the female dog may exhibit signs such as swelling of the vulva, a slight bloody discharge, and increased urination to mark her territory. She will also likely be receptive to male dogs during this period but will not allow mating.
The second phase, estrus, is when the female is most fertile and ready for breeding. This stage usually lasts about 9 days as well. During estrus, the vulva remains swollen, and there may be a decrease in vaginal discharge. The female will now allow mating with male dogs.
The third phase, diestrus, begins after mating or if no mating occurs, typically lasting around 60-90 days. During this stage, the body prepares for potential pregnancy. If the dog is not pregnant, the hormonal changes will lead to the final phase of the cycle.
The last phase, anestrus, marks the end of the estrous cycle and the beginning of a period of sexual inactivity, which can last from 4 to 11 months. During this time, the female's body rests before the next cycle begins.
It is essential to note that individual variations can occur, and some Staffordshire Terriers may experience shorter or longer heat cycles. Additionally, older dogs may have irregular heat cycles compared to younger ones. Regular veterinary check-ups are crucial for monitoring the health of your dog throughout its life, including during the estrous cycle.
