6 Month old puppy has a red eye. Know whats wrong with her eye?

As i said, she is about 6 months old. I am very worried. She has just recently been hit by a car, she is fine. We took her to the vet. But i just noticed that the white part of one eye is completely red. Thanks!

could be ruptured blood vessels from the impact of the car, however it could also be actual trauma to the eye that may require medical attention. I would take her back to the vet for a recheck. If you wait too long you may end up having to take the puppy to a specialist or end up having to do surgery.this may also be completely unrelated to the bump with the car, puppies, while playing can induce trauma to the eye. i have seen injuries happen from playing with sticks, playing in the yard, playing with another dog, attempting to play with a cat... it can be hard to say with puppies. Allergies may also be a culprit as well (though both eyes are normally affected). Abnormalities can also show up at this age, such as cherry eye or entropion, though rare, but possible.Needless to say, i think another trip back to the vet may be in store. Like I said earlier, ask for a recheck, some vets do these checks at a cheaper price than the initial exam.
