“Pinkeye” has two definitions: bovine pinkeye is a specific bacterial disease that only affects cattle; otherwise, “pinkeye” is a generic synonym for conjunctivitis.
Dogs can’t get bovine pinkeye, but they can and do get other types of conjunctivitis. It may just be less noticeable in dogs because the white sclera of their eyes isn’t as prominent as humans’.




One thing that might be a factor is the Bernoulli effect (moving air has lower pressure than still air). When your head is in moving air but your chest is in relatively still air, that would create a pressure differential that makes it harder to draw air into your lungs. On a motorcycle, your whole body is in moving air so the pressure differential wouldn’t exist.
