Dog meat in my food? I asked for pork ! That's disgusting and sad!

Yesterday on the Daily Mail Uk

Chihuahua chow mein: Six Chinese restaurants shut down in Tijuana after a horrified customer discovered DOG meat was being served up as pork

• Customer witnessed dog being butchered at Lo Yen City restaurant

• It was killed to be served as a pork dish, it has been alleged 

• Police raided the restaurant and arrested five people, including the owner

• Officials on the scene discovered a decapitated puppy in a rubbish bin 

Why is Dog Meat so disgusting for us? I mean, we order pork, sorry i meant we order PIG flesh and it doesn't bother us a bit. Pigs are genetically very close to humans, their heart will pump if placed in a human chest, we are so similar that they say humans taste like pig. Pig blood will even keep you alive if transfused into your blood. Wow... we can't say the same about our dear dog at home, can we?

I found this online which reflects exactly how I feel currently regarding the dog meat trade in Asia:

"The Korean culture views dogs and cats as food.  That certainly was foreign to me as an American.  We shared our homes, our beds, our lives with these beings.  We loved them.  They were family, friends.   Our culture, on the other hand, viewed cows, pigs, chickens, turkeys, lambs, fish, even rabbits as food.  How could I, in good conscience, object to the culture of another country without examining our culture.  In that moment, I became a vegetarian.  To be able to criticize the customs of one culture without being a hypocrite I would have to reject our culture of eating the flesh of any animal.  The thought of anyone eating Casey or any of his relatives appalled me.  But weren’t the lives of cows, pigs, chickens, turkeys, lambs, fish and rabbits just as valuable?  Of course they were and are.  Casey and the love that I had for him opened my eyes and changed my view of the world and transformed my lifetime love of animals into a respect for the lives of all non-human animals.  "

But why, why do we have this cultural speciesism? Melanie Joy asnwers... Her TED talk is always a good watch, if you haven't already!
