To be perfectly honest...No, I don't think a Yorkie is right for you. And it really seems like maybe you already realize that seeing as you have listed the factors working against you.
I would really wait until you're life becomes a little more stable, you and the new hubby have moved, settled in and you are not away from home so much and can spend more time with the dog. You seem to have enough in your life to easily stress YOU, just imagine how it would be for a wee little one.
If you've only been eyeing them for a month, I would really suggest that you resist that impulse urge to snatch one up. (I know how hard it is.
) Stick around here, learn more about the pros and cons (yes, cons) to this breed and don't rush things. You will learn a million things you never knew you never knew and it will only help you to make a better decision and choice in the future regarding getting a little one.
