their night vision is not as good as a cat's, but much better than human's.
Dogs have much better night vision for 2 reasons:
* They have more rods (which enable night vision).
* They have a structure called the Tapetum Lucidum
This is a reflective surface behind the retina (area including the light sensitive cells) that reflects light back through it (gives the eerie shine at night).
Here is a great article about canine vision> http://www.uwsp.edu/psych/dog/LA/DrP4.htm

Well, they don't go blind at night, now do they? They see differently from people.
