Could my dog be blind???? PLEASE ANSWER!!!?

its a possibility, is he the runt...the teacup? if so he does have more sensitive spots than "normal chihuahuas" but as for the squealing when you pick him up. a lot of chihuahuas dont like to be picked up from there "armpits" or under their arms. it does hurt them alot. if you were three pounds and this thing was hovering over you and pick you up by your armpits "espiecially girls if you know what i mean" it hurts so keep that in mind. and it could be a face. he may need an eye cleaning or rinse. and there is im sorry to a possiblitie he could be blind. the easiest way to tell is take a picture of your dog with his eyes open if the dogs eyes are gray and shiny looking "at the same time" hes most definatly blind! im verry sorry!
