When we got my dog logan they said he was a min pin x chihuahua. I highly doubt the chihuahua part. he dosn't look like a chihuahua. He is way too big. He wieghs 20lbs. He is brown with other colors mixed in. We didn't get his taill or ears cropped. he looks kind of like a min pin and has the same attitude as one, but agin is too big to be a purbred. What else could he have in him?
