Hello and welcome to Yorkietalk. As you mentioned this is an awesome sight to ask questions, read stories, share picture's of our fur-babies and everything else inbetween...
It sounds like you just are anxious to receive your new little Yorkie. The excitement can tend to make one worry, try to relax and know in just a few days your little one will be here.
Correct, there is no such thing as a "tea-cup"..It usually is just a breeder's way of justifying a higher cost to charge for their Yorkie pups. Yorkie's can be small, medium, even bigger yet but they are all just still Yorkies. I have seen through my own personal Yorkie expierences that the smaller ones can tend to have extra special health concerns. The smaller one's need to keep their sugar levels regulated, their bones are real tiny so even the shortest jump can be damaging to their joints/ligaments. Also, I read you had children younger in your home, it's important for your new fur baby not to be stepped on accidentally or smashed in a closing door by kids walking out.
You will be busy these next 4 days getting prepared for your new pup, so that will help take some of your tension away. New bed, kennel/crate, food, dishes, safe chew toys, etc...Also, you might want to stop by your vet for some Nutrical. It is wonderful for the little babies. It is a health supplement that keeps their sugar regulated. Also, your new pup will be nervous coming home and the Nutrical helps with the stress levels in their bodies also. It's a lifesavor if your little one does go into a hypoglaucemic shock.
Feel free to post your questions on YorkieTalk, we love to help out when we can.
Also, don't forget to post pictures of your new one, we love pic's the most!!
Have fun these next 4 day's with all your new pup prep, it's an exciting time...Im jealous, I wish I was waiting for a new Yorkie pup. I have Schatzie who is 8 months, but I would love a million more!!
