I think I saw pictures you holding him on your Tumblr, now that I recall. He was soooooo adorable. <3 And our dogs wouldn't really hurt anyone either; even the temperental one. He's just more bark than bite, haha. XD And soooo cute. <3
My parents have a Yorkie just like that. It's the temperament of the breed. He's a sweetheart though. I love him, and I'm sure I'd bond with your chihuahua in no time. x)
