Girl I am in the exact same possition. I am still looking for my first yorkie its been 2 months still no pup. Although I have had small dogs in the past as a younger child like long haired chihuahua, palmeranian and Tibetan Terrier but my main knowlege is big dogs like rottwelers, pittbulls and large mixe breeds. its going to be my first yorkie and i am strongly against petshops, but never knew how hard it is to find a breeder and even harder to find a good one. Theres only one that i keep running to over and over again its Debs site
http://www.sumtoiyorkies.com/ i had the pleasure of speaking to her on YT. She is extreamly knowledgable about yorkies and even helped me look for my ideal yorkie even if it wasnt from her. The more i learn about her and her yorkies the more it makes me want to get one from her. she has 4 pups right now just over a month old but maybe she might have them available by march.
