Here is a picture of my iggy's (Italian Greyhounds):
Their names are Prancer and Vixen. (My Prancer is a male though!) Italian greyhounds are just like the larger greyhounds in temprament and looks, but they are miniature. My male is 11 pounds and the female is 10 pounds. They are truly lap dogs, because you can't sit down without them climbing into your lap. They chase each other just like your's Rozzie! Greyhounds are just born to run, they love it so much! They are such gentle dogs too! You will want to have that second dog so Prancer can have company. They love to curl up together. I'm sure you are excited and can't wait until she is with you! Congrats!
