I grew up around a farm for a while, and my stance today is that I only eat animals I'd be willing to kill myself. Which pretty much just knocked pork out of my diet, since as you pointed out they are very intelligent animals. The overlap between "smart pig" and "dumb dog" is substantial.
More like dumb pigs are on the level of smart dogs. "Pigs are widely considered to be more intelligent than dogs and equally as intelligent as chimpanzees. "
