Dampness by her vaginal area can be a sign of her cycling. If there is an odor or color to the discharge then i would be concerned. Is her chin wet as well?
Honestly a yearly vet visit is a waste of your money. Its extremely stressful to your chin which in its self can lead to issues (stasis, bloat, parasites, upper resp...). Chins should only leave the house on an as needed basis.
