I'm not sure I'd go with rhyming names...although they sound cute it might be confusing for the puppies! Why not check out the thread for yorkie names...there are tonnes that popped up! My husband and I googled several lists of dog names...we each wrote down our personal favorites and narrowed it down from there.
It also helps to have the puppy at home...we were sure that we would name our female Diva...but one look at her sweet little face, we knew that name was not going to fit her personality. Who knows....maybe your pup will introduce herself to you
