Dogs Benefit Humans in Many Ways

What I say in my headline today is actually superfluous. Of course, dogs benefit humans in so many ways, it should be unnecessary to say so. On the other hand, here is another benefit to humanity: a genetic fault in dachshunds may explain a certain kind of blindness in humans. These blindnesses are similar, as would probably be the genes causing it. This only goes to prove, yet again, that the benefits that humans get of dogs are countless.
