Dogs are highly intelligent. The majority of stock are not. The only exception that comes to kind are pigs.

More important is the incredibly abusive practices carried out in these countries. Some insist that forcing the other dogs to witness the killing and butchering improved the quality of the meat. And then there's the trade of slaughtering not just cats but kittens specifically for fur. They aren't killed before being skinned. 

Eating an animal is eating an animal but theirs a lot to be said about how a given culture treats the animals it uses as livestock. There's even been a shift in attitude in some Asian cultures.
