Hi there , and welcome to YT

You have Two beautiful yorkies. Your Chloe is 100% full yorkie to me! She is a silver blue yorkie.. That is her coloring, and is recognized as a pure bred Yorkie! Even though her weight is higher then 7lbs , she is still a Yorkie .
There a a lot of people here on YT that get rude comments from strangers all the time about their Yorkies ! Try not to let it upset you. Your Chloe is a yorkie and she is precious.
