Sophie I will put it on here, well first thing to do would be to dab her Vulva with a white tissue to see if there is any colour, brown or dark red would say start of season, bright red in season, they don't normally turn tail, (swish it to the side) until they are hot and ready for mating, it she was she would of be mounted constantly by every dog at training and Sid too, (even though he has lost his tackle). The Vulva become swollen, and can be almost three times bigger but in a younger bitch may just go a little larger, t will be bigger though.
First do the dab test, let me know either ring or e mail if you rather Sophie. Summer's daughters all came into season around the same time so Diva's girls may well do the same.
