I always find it very hypocritical that the same people who have no problem eating pork are outraged over people eating dogs in Asia.
Pigs have never been domesticated in that way in large numbers and have always generally been used as food, or for limited other purposes, occasionally as pets.
I think this difference in lineage and purpose leads to a very meaningful distinction.
In a society, people seem to taboo things which indicate a general lack of emotion toward other members of the society. With farm animals, there are social (and religious and legal!) rules around maintenance and slaughter, and farmers deal with large groups of animals, so the relationship between farmer and animal is one-to-many and doesn't leave much room for long term emotional bonds to form.
For working animals and pets, the bond is one-to-one, and involves working directly with the animal in question. The relationship with a working animal is much closer to the relationship with another human. Thus, killing a dog in a society where the role of a dog is to herd cattle makes you seem dangerous to the people around you, while killing a cow in a society where cows are food is explicitly sanctioned and not an indication that you might murder your co-workers.
You know how Hitchhiker's Guide to the Galaxy has a pig that has been genetically bred to want to be eaten? Like that is it's greatest desire in the world.
Dogs have been selectively bred over thousands of years to want to be our friends - to trust us, and to work together as companions. To deliberately kill and eat an animal like that is worse than eating any other.
The dog species doesn't trust us (in any meaningful way). Individuals dogs do. Likewise, regardless of what we've bred "food" animals for, properly cared for farmed animal will hold the same implicit trust in a farmer as a dog does with his owner.
These evaluations need to be made at the individual level to make any sense.
A pig wants to live just like a dog does. They want to avoid pain and suffering just like a dog does. They seek comfort just like dogs. The fact that they were bred for a certain human purpose, doesn't change any of that.
Definitely are Asia (Laos and Cambodia, I think)
You can find the same exact "smile" in goats, sheep and pigs, they're definitely not making that face because they're happy.

But a dog's smile is so much more, posture, sounds, tail wagging..
A dog's smile makes me smile.
And for that matter, humans can bare their teeth as well..
Or the average age of the site is too young to remember Pulp Fiction.
« Some people have gone so far, especially with show pigs, as to slather sun screen onto their pigs when they know that they will be out in the sun for a considerable time and they don't want them to get dirty with mud. » -- http://petcaretips.net/pigs-sunburn.html
You could also just keep your pet pig indoors all the time.
