My husband for Valentines day got me Titus. I have never had a Chihuahua before and I was just wondering if you all think he is fullblooded. It doesn't matter to me, we totally love him, I'm just curious. Alot of people think he is mixed with a terrier. He has a very curly tail like a pug and a underbite, and longer legs than most of the chi's that I have seen. We got him off of craigslist for a very small rehoming fee. He is 8 pounds and 6 months old.
