Yorkdaddy and Babiegurl, hope you both have great luck with your dogs. I was lucky enough to get a wonderful little dog from what I call a pet breeding and she is the most marvelous little dog.
We already had 6 Chihuahua's when I had the chance for the Yorkie and it is amazing how different the two breeds are. Even though they are both small dogs they have totally different characteristics and behaviour.
Bella (our Yorkie) is much smarter than our Chihuahua's (don't tell the Chi's)
and she never stops moving. My husband and I said she should have been named EVEREADY like the battery!
She has had no medical issues, no illness (so far) and no major personality disorders.
I am very much against puppy mills and that always gets me going but now that you have purchased your dogs the best advice I can give is to make sure you don't fail them. Remember they are not disposable and even if they have issues it falls to you to care for them. Sickness and in health. My hubby and I stretch $$ pretty close to take care of the furkids we have but they repay us in ways to numerous to name.
Good luck and I can't wait to see pictures of both when you get them home!
P.S. My Bella doesn't bark unless she wants to play or someone has something she WANTS....then watch out!
