Question from Julie Wilshaw: at wot age do staffies.stop having seasons? Answer from Shanika Winters: Hi Julie, you have asked an interesting question for all owners of entire (unspayed) female dogs. In short entire bitches (female dogs) do not stop having seasons. I will discuss what seasons are, signs that your bitch is in season, when seasons tend to start and what happens as your bitch gets older. A season is what we call the time when a bitch is able to get pregnant (reproduce). An average season lasts approximately three weeks, during this time the vulva (outside part of the bitches vagina) becomes pink and swollen, there is often a bloody discharge for around 9 days, this is followed by ovulation (eggs being released from the ovaries) and after this time things start to settle back to normal. Bitches usually have one to two seasons a year. During a season bitches give off pheromones which attract entire male dogs from a long distance away, also at or near the time of ovulation the bitch may stand with her tail held up and to the side to allow herself to be mated. Some bitches can become aggressive during their season others more clingy.
- Anoestrous - not in season, around 6-8months
- Proestrous - around 9 days, vulva swells, vaginal bleeding
- Oestrous - around 9 days, usually stop bleeding allows mating
- Dioestrous - around 2-3months, high levels of the hormone progesterone which can sometimes lead to false pregnancies
