How long does heat last in Staffordshire Terrier dogs? - in detail
The duration of heat, or estrus cycle, in Staffordshire Terrier dogs is similar to that of other breeds. On average, the heat period lasts about 18-21 days, but this can vary from dog to dog and with each individual cycle. During this time, the female dog will experience several phases:
Proestrus: This initial phase typically lasts around 9 days. During proestrus, the female's body prepares for ovulation, and she may display signs of heat such as swelling of the vulva, a bloody or straw-colored discharge, and increased urination to mark her territory. She will likely be receptive to males but should not be bred during this phase, as it can lead to infertility.
Estrus: The estrus phase is when the female dog is most fertile and ready for mating. It usually lasts about 9 days, but this can vary. During estrus, the discharge changes from bloody to a clear or yellowish color. The female will be more receptive to males and may stand still or wag her tail when a male approaches. This is the ideal time for breeding if you intend to have puppies.
Diestrus: After estrus, the diestrus phase begins, lasting around 60-90 days. During this period, the female's hormone levels decrease, and she will no longer be interested in males. The discharge will stop, and her body will prepare for pregnancy if fertilization occurred. If the dog is not pregnant, she will experience a false pregnancy, which can include behavioral changes and even milk production.
Anestrus: This is the final phase of the heat cycle, lasting until the next proestrus begins. During anestrus, the female's reproductive system is inactive, and her body focuses on other functions. The length of this phase can vary greatly among dogs, with some entering heat again as soon as 4-5 months after their previous cycle, while others may take up to a year or more.
It's essential to monitor your Staffordshire Terrier dog's heat cycles and consult with a veterinarian if you notice any irregularities or have concerns about her reproductive health. Regular check-ups can help ensure that she remains healthy and happy throughout her life.
