I'm a somewhat new Yorkie owner. I got Mango on July 2nd.
He is a lot of time and commitment. I don't think your school hours are that bad, but I think you are better off with a Young, but not adult, Yorkie if you'll be gone 3 days a week for 7 hours. Unless you don't mind cleaning up a huge mess from going to the bathroom.
When I'm at school (I'm in 11th grade, gone 7 hours a day 5 days a week now), my mom takes care of Mango. He does not like to be alone and will bark if no one is with him, cry, and sometimes if he wants our attention, he will pee.
While I think out of all my dogs (Siberian husky, and pug,) Mango is definitely my, dare i say, favorite, of them all because he has the MOST personality. I treat him like my kid! He goes wherever I go (except school), and follows me everywhere in the house. He is expensive, and costs continue to add up, but it is worth it. He is my baby! |
