All of the dogs I've known are literally idiots. They can't even do the things they were bred and trained for right. Although calling them aggressive might be a better way to sum up their behaviors.
Meanwhile I feel like my cats understand me, even when they weren't bred or trained for anything. Sometimes they leave the house for weeks at a time and then show up at home alive and well, apparently having hunted for themselves.
I don't like dogs because I don't find them very intelligent. However, wolves I like. You can't not like wolves (unless you had some past trauma involving them or something like that)
