My boyfriend and I got our puppy Paco a few weeks ago. The breeders said he was a mix chihuahua and american bulldog and possibly shepard. Many people are saying he looks chihuahua and resembles red nose pitbull. We called the owners and they said they don't know the father and they never even had the father. What do you guys think!? Paco is a little over 3 months and has the body of a chihuahua but has the upper body of some sort of bulldog and has many wrinkles on his forehead.
