Yes, Genteal liquid gel for moderate dry eyes (orange stripe on box), NOT the Genteal gel in tube (red stripe on box) , is very helpful for dry eye, in dogs or humans. I've tried less costly brands but they seem just like water and are not nearly as comforting.
A funny thing, dry eyes sometimes cause the eyes to tear like crazy, which seems counter-intuitive, but true, and the Genteal does help.
