That last picture is my favorite!  Definitely some chow in there...she has the dark tongue which I believe is a chow trademark.  Looks like a sweetie.  My Sandy has more husky/shepherd in her, tons more hair.  
 
Are they all getting along well still?  My Sandy is not a huge fan of the Yorkies.  She tolerates them, and that is all.  Because of that, they have very limited and only supervised time together.  Sandy is just not real fond of other dogs.  There is one exception to that...she seems to love the next door neighbor's Yorkie.  Go figure!
 
 
Wishing you all the best of luck and a very blessed Holiday season!!
