Well, Lid, I can argue along the same lines for abstaining from beef.

Without cows to pull the plow, agriculture would not have been possible. Much of the architecture in the ancient world would not have gone up had we not had this beast of burden to aid us in our endeavors. Cows provide many cultures with milk, cheese, and butter, one of the most important sources of protein and calcium. Without it, the culinary map of the world would be very different. I'd go so far as to say, without cows, civilization as we know it might not exist.

And an additional plus, about a billion people on earth worship them as holy animals.

So yeah, other than that cows gave us civilization, they're just like any other animal.

Since pigs are more intelligent than dogs, and we're more indebted to cows (and arguably horses) as a race, dogs seem to be fair game.
