Eating a dog is no different than eating a cow. Meat is meat. If the cow farmers in the US decided to unleash their herds in a populated place it would also be a bad time...
Your first post didn't make any sense to me, either, until you explained it, and now it makes sense, although I'd recommend clarifying as "land animal meat is the opposite goal of fish meat" or something like that.
But yeah, I'd never thought about it that way. Interesting.
