Sounds like you already have the answer. You are young and thinking of a family and these little dogs are cute. But most of us use them as our kids. And little kids you have to watch with these fragile little ones. Plus some of them get very jealous. Not sure if you want to go through that. There are other dogs out there that are small and better built for kids down the road. If you really must have a dog maybe you need to think about something that will fit with you future life with kids. Hope you decide but yorkies are special when the timing is right.
We have this as our 2nd life, all the kids aren't home and now these are our babies.
