Okay, there is a Chihuahua in my family. My husband bought him for his grandfather as a comfort before his grandfather died. His name is Skeeter. Now Skeeter is not a big fan of people. He will bark and bark at strangers. But he is truely a chicken in a dogs body. At the same time, he does NOT like my three-year-old brother-in-law, and has bit him several times. (The 3 yr. old parents let him pick on the Skeeter. My son Austin, 2 yrs. old is loved by Skeeter. But Austin is not allowed to pick on Skeeter either.)

My point, Chihuahua's act big and bad, but I've never heard of one biting. This is just insane.
