I have a female Staffordshire bill terrier. She came into season on the 20th February and I mated her the 1st March, they tied for approximately 10 minutes, after that the male wasn’t interested in mating again. I calculated it from the first day of mating which means she is around 65 days today but no signs of labour. She is only eating little bits of her food, still weeing and pooing fine. She started loosing bits of fluid yesterday, like a clear/white mucus but no other signs or labour except shaking and sleeping a lot. She has put weight on and her teats have got darker and bigger, plus her vulva has become enlarged.. Any ideas on what could be happening?!
