first welcome to yt..........second....she is gorgeous..........to answer one of your quesitons........yorkies go into heat every 4-12 months.......with the average of them going into heat every 6-8 months..........and those are pretty much the signs.......you may also notice that if there is a male around he may start "paying more attention to her".....and frequently sniffing her........good luck
