Pigs are not more intelligent than dogs. That's flat out misinformation, and you are propagating misinformation, i.e. spreading a myth every time you repeat that false information.
I don't think I'm being rude, although I don't have a lot of patient for people that willfully spread misinformation.
Maybe, just maybe, do some more research other than believing what the first link in your Google search results brings up.
One source has been posted thus far, and it contradicts what you've said. In fact, the entire first page of Google's search results for "pigs vs dogs intelligence" brings up nothing to support your point. (Low-quality sources, but again, it's currently low-quality vs no-quality.)
It's (IMO) somewhat rude to demand compliance without supporting your position.
