Jessica Thomas New York, International 8/6/2014 12:29:19 AM I love chihauhaus. I bought a short haired one with a tan fur colour, I called him caramel! He is totes adorbs and loves to curl up on my lap. But the other day he started to get aggressive. He bit my 6 month old yorkie terrier and now barks a lot. What can I do? I love him so much, but he's turned into a beast! Please help!
