Sad! We have to get rid of our dog!

So we have a Chihuahua, named Napoleon. He is 3 years old. About a year ago, he bit Julian on the arm a few times. He seemed to be over the biting thing, until this week. He's bit Julian twice this week alone, once on the foot, and once on his face! Poor kid. Napoleon is a good dog, he just can't handle kids. He's never bit me or Barry, I think that kids just make him nervous. If you know anyone that would love a Chihuahua to spoil, someone that doesn't have kids, and doesn't plan on having kids, let me know, please! He's a really cute dog. He's about 15 lbs (we were told he's 100% chihuahua, but I feel like he's not. He's big (for a Chihuahua).
