i like the advice of going where your friend got Teddy. If that is not an option, I would just check local yorie breeders and if you are wanting a bigger yorkie...just start asking the breeders if they have any large yorkies. then just go with your gut...if you meet a pup and bond with him..it won't matter if he is silky or yorkie. you will have the pup you were able to bond with. i'll warn you, yorkie or silky...these pups are heart stealers. you will fall in love with them all
there is nothing quite as irresistable as a yorkie pup
good luck!!
