Castello di Riva - Ponte dell'Olio - Piacenza - Italia

Just as the title says really and just out of curiosity, is there an age when their ticking/spots stop coming through? My girl will be 2 next February and her spots have been coming out a lot recently. Shes always had really speckled skin (she’s black and white) but up until maybe 6 months ago didn’t have loads of black ticking outside of her larger markings, but her skin is so speckled with black spots with white fur coming off them up until recently when a lot more black fur spots are showing. Will the hair on the black skin spots start turning black or is the speckled skin and ticking unrelated?

Again just out of curiosity I’m fascinated by the changes in her coat 🐾
