Welcome to YT! There is a GREAT thread on here that talks about kibble that you could be very helpful for you. I don't know how to link to it so hopefully someone will help me out
As far as a "sign" for getting a second yorkie, my only advice is to remember that the purchase price is such a small portion of the costs by the time you start adding in vet bills, etc.
We wish you the best on your decision!
