The unique problems for me with dogs is not just that they're evolved to interact better with us, it's that in many places where they eat them it's believed that it tastes better if it was terrified and in pain when killed. So you can imagine how they're treated when getting prepared to slaughter. No easy life or death for food dogs.
Then there's several places in Peru where it's believed cats taste better if drowned.
Not that we treat our livestock great in the west but some cultures take it to a horrifying level due to tradition.
