Snickers is smaller than the normal size Yorkie so I am told. I like them small also. She is the size of our friends 8 week old Boston Terrier. She is under 4lbs and is a yr old now.
You need to do what you feel is best for you, you are not one to mistreat your animals or any for that fact so just love the one you get and spoil it rotten
As far as the pricing goes. I am not sure about pricing of Yorkies but I do price a little higher for my show marked Dane pups out of our litters. Is this pup you want more cause of her size or is she show marked? Sorry I am not sure about Yorkies and how it all works on this end so just a question and a thought to why she may charge more for the pup you are looking at.
