Ahhh congratulations on your first Yorkie!
I first got Mango last summer, July 2nd to be exact, if I remember the date correctly! The first few days were tough, Mango was really nervous the first night, and next day. He wouldn't eat/drink or go to the bathroom, but then he warmed up. Soon, he was completely attached to me, followed me around the house EVERYWHERE. I stood up to go to the kitchen for water, he followed, I go to my room to find something, he followed. Yorkies get very attached to owners, and that is what i love!
Yorkies have SO much personality. I have two other dogs (pug and a husky) but out of all three, Mango has the most personality by far. Hes my bud!
Good luck with your new little one!! You will love him I'm sure! I bet you're so excited!
