Hello all! Yesterday I fell in love with a Chihuahua puppy, he's 10 weeks old and he has the most adorable apple puppy head. They're selling him for $750 and he's going to grow up to be 4lbs (Toffee's weight). Do you think it's a good or bad idea to get another dog now? Especially since Toffee isn't 100% house trained (he's 80% there, and 7months old). Is it a lot of extra work and am I going to be very hassled by having two dogs around?

Do Chihuahuas and Yorkies get along? Finally, what are the negatives about Chihuahuas?
Thanks you guys!
