Dogs don't cry like humans do. If you see a discharge coming from your dog's eyes, then there is a problem with the eyes. Make sure to gently wipe away the discharge with a damp clean cloth. If it continues, then take your dog in to be checked out by your Veterinarian. Eyes are too valuable to just ignore problems.
Messages travel from the dog's eyes to their brain.
