My rescue, Ella Bean, I believe is a 'Morkie' She was a rescue, so I don't have her exact lineage, but she is definitely half Yorkie and the other half seems like a Maltese. Mine is teeny - she was 1 lb. when I got her at 5 months and now she is a year and about 2.5 lbs.
I will say, she is a great pet, with an awesome personality. She rarely ever barks, only during play, is loving, affectionate and brave. She knows she is small, but plays with my bigger dog without any fear. Plus, she was SUPER easy to potty train!!
