Perhaps I need to stress that the third eyelid is a perfectly normal part of every dog's eyes. Most dogs never show it, but if it does emerge it can be a useful pointer to an infection such as conjunctivitis, which can normally be cleared up quickly with drops. Anyway, I may be completely wrong, judging from a not-very-clear photo!
