His inner eyelids (as in: what is seen when you pull down on the flesh beneath the eyes) are quite red and have been since we brought him home to live with us two months ago.
He seems perfectly healthy in every way, is almost 8 months old and very active. I'm feeding him Orijen dog food supplemented with raw meat and cooked bones here and there. But, actually, I do not think it has to do with diet because the redness was there when he came to live with us. I should also add that we live in a very high heat climate (average of 100 degrees daily for several months this time of year).
Hmm . . interesting stuff to think about. Thanks for the replies, friends. No, there doesn't seem to be anything else that stands out as unusual with his eyes and his health in general. Guess I'll just keep an eye on it (jeez, no other way to say that!) and watch for any changes.
