The Bible says it's OK to eat dog? Really?
Mark 7:18-19
18 And He *said to them, “Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, 19 because it does not go into his heart, but into his stomach, and [g]is eliminated?” (Thus He declared all foods clean.)
There’s other passages that say God’s cool with eating any animal. The only real rule against eating certain meats has more to do with their being used for sacrifices to idols. Even then it’s more about bringing down your weaker brothers than it actually being harmful to your own soul.
The Bible forbids the eating of pork but I've never come across anything relating to dog or cat either (lapin de toit) for that matter.
Dog and man are symbiotic creatures which are beneficial to one another's survival as species. I don't think dog should be at the top of anyone's menu. That said, if things get tough, protein is protein.
