Hi LBelle, welcome to the BEST place on earth to learn all about Yorkies and their unique traits and personalities. The members on here are wonderful and will willingly share their knowledge and support. You've come to the right place to become educated and ready to be the BEST parent possible for your new little family member.
Please, please, please be cautious about purchasing a puppy online or from a backyard breeder. This breed can carry many serious genetic issues if they are not bred responsibly. You'll pay less up front but $$$$$$$$ in heartbreak and vet bills if you have one that is not well bred. Don't take a chance There are many AKC breeders that will share a healthy puppy with you and believe me it's worth the time and effort to research your breeder carefully.
Bella is my first dog EVER and she is the joy of our lives. She is 4 lbs. of happiness and adds so much joy to each and every day. I can't imagine life without her. We rehomed her and luckily the original owner took the time to be sure she was from a reputable breeder. We never realized what a chance we were taking when we rehomed her with no regard to her parentage. We were fortunate.
Anyway, good luck in your search. The more time you take, the more happiness and joy you'll have when you find the right puppy for you! Keep us posted and remember we love pictures!
