Ok I just got a chihuahua from someone i didn't know that wasnt taking very good care of it for $50. They claim its around 8 months to a year and 2 months. Hes about 10 lbs right now. Any ideas on an age or what mix breed? I was thinking maybe a chihuahua-rat terrier mix. He looks just like a chihuahua... not fat or anything looks actually pretty healthy. But big for a chihuahua. He has the pointy ears like a rat-terrier too. Thanks for ur help
