Which way do dogs wear pants

Ian: A dog would obviously wear his pants like the left side because pants are made to cover up legs. The definition of pants is having individual leg portions that reach typically to the ankle but sometimes to any of various other points from the upper leg down. On the right side, he is only covering two legs so according to the definition the right side is incorrect.

Rex: I disagree with Ian. I think the image on the right side is way more logical because yeah, on the left the dog's legs are covered up but the dog's anus is exposed. Personally, I think pants are used more for the reason of covering up areas that you don't want the world seeing. I think that keeping the anus covered is way more important than keeping all four legs covered up.

What do you think?
