Dogs do shed tears, and dogs protect their eyes by shedding tears Dogs, like humans, are capable of secreting two kinds of tears, one is the basic tears and the other is the reflex tears. Basic tears: Basic tears are produced between blinks, the amount produced is so small that we can barely feel it, and the main components are salt and sterilizing substances that have the effect of keeping the eyes moist and sterilizing. Reflexive tears: Reflexive tears are a protective response produced by conditioned reflexes when foreign objects and dirt such as sand, dust and insects enter the eyes, and can clear foreign objects to keep the eyes clear.
