that is the way that some are - all chihuahua's have the "apple head" look, their eyes are always going to look like that (that is a standard for the breed), of almost 30 years of being around them, I have never seen a chihuahua with a tongue hanging out all the time - I think that is a trait of certain lines, but I am not for sure on that as I have never experienced it.

LOGAN - you aren't a vet - if you were, you would have a lot more technical & professional terms other than "old man". Geez. Look at some reputable websites of breeders & you will see that the standard for chihuahua's is the apple head & their eyes do water & have a little bit of a bug eye to them. Go to the link above & you will see what to expect.
