Hello all, I'm brand new to this forum and I'm looking for some help.  My husband and I just returned from our honeymoon to discover that our Zoey has gone into the heat for the first time.  How long does a heat cycle usually last for a yorkie and how often should I expect cycles to come around?  Poor girl, she's wondering what she did wrong as she's now wearing a diaper in the house.  
  
Thanks for your help!
