Welcome to YT!!! With this being your first Yorkie and your first inside dog, you will find this site overwhelmingly helpful. The parents of your new pup are in the standard range so your pup PROBABLY will be too. I'd guess probably around 7 lbs also....but you never know. 7 lbs sounds like a lot, but I don't think it looks like it when it comes to a Yorkie. Also you won't know exactly what she is going to look like as an adult either. Have a great time here, it can be lots of fun
