If people weren't so ignorant about the role dogs have played in the advancement of humans in countless fields from theatres of war to scientific exploration to bringing solace to the loneliest of souls to saving countless lives they might be slightly less likely to dismiss them in the way some on here have.

Similar things can be said about horses but I don't see people getting so upset about them getting eaten.
