My avatar is Cookie the chihuahua. MIL adopted her from Humane Society @ 6 months because she did not train her well. I found out I went adopted her. I have broken her of a lot of bad behavior. She never barked until a neighbor got a barker. She is smart enough when someone calls her stupid or talks bad about her, I don't know how she knows but, you can tell by the look on her face that she knows. She has never bitten or tried to bite anyone. I prefer poodles and Shih Tzu.
