eating dogs,cats may be some culture and its probably accepted in some countries.

But there are also other eating habits too.

For many of these big well known restaurants serve all of kinds of animal meat for luxury.
They pay at very high prices for all kinds of exotics animals. (especially endanger animals)
the more exotic they are, the more money they pay. 
For others, it is illegal to sell or serve these meat as delicacy.

for some poverty country they do not have a choice to choose their food because they struggle to survive.

the question is do we eat to live or live to eat?

Dog meat is regarded as a masculine dish in Korea, I don't know how many people eat it because many people detest people eat it. Anyway, whenever eating dogs is made an issue I come to think it's convenient to side with the public whatever. As you know there are absolutely more people who love dogs than those love pigs, it would be why they blame the people, thinking nothing of saying "I eat pigs."
