So here is why cats will for ever ever be inferior to dogs.
When I was a kid, my family got an Irish Wolfhound. They are the biggest dog race in existence. Now, Irish Wolfhounds are called Wolfhounds because they were bred to take out wolfs. Which explains their size. But it also had the effect that Irish Wolfhounds were not only really big, but really big and aggressive. Which lead to them almost going extinct when it became less of a necessity to have dogs which hunt and kill wolfs.
Almost, because finally, a rebreeding program was undertaken. The focus of this new program was to make Irish Wolfhounds tame dogs who are safe to be around.
They succeeded (mostly - I get into this right way).
Here is a picture:
And when they are angry
So we got ourselves such a new-breed tame Irish Wolfhound. And while being really big and accordingly scarry to other people, he was the most peaceful dog I have ever known.
No matter if people or other dogs or even birds - he showed no aggression towards anyone. The maximum of his aggression was taking a half-hearted bite at some fly bothering him. He didn't learn to properly bark until we got ourselves a second dog (a terrier - not the best of our decisions). He was the arch-type of the gentle giant.
So we thought.
Because there were two instances were our Irish Wolfshound seized to be big and gentle, but got big and threatening.
One instance occurred when my big brother took our dog to a local bar/club. It is not to be imagined like one of those big commercial establishments. It was a very "local" kind of thing, where everyone knows everyone and all is rather chilled compared to those ordinary commercial establishments. Just to explain why it was even feasible to take a dog there. So he took our dog there and being the big lazy comfy ass he was he laid down at some edge and chilled. Now there was this one guy my big brother wasn't on good terms with. I am a bit fuzzy on the details, but this guy was on to my big brother in a quit adversarial way. So this guy enters the room, he and my brother see each other and suddenly, our Wolfshound gets up and does something so far totally unknown - he bares his teeth like animals do if they want to threaten someone and makes a quit impressive snarl.
Now to be straight about this - this dog never ever did this before. Ever. But at this instance he does, clearly directed at the guy who is with odds with my brother. Moreover, my big brother isn't one to invent stories, so I hope you believe me if I say this is genuine. Well needless to say, the guy decides to leave the establishment.
The second instance was even more awesome. A lot more awesome.
Me and my family were on a camping trip through-out Italy using a camper vehicle. We had planned camping sites for every stop. But everyone who has been to Italy knows - Italian roads can be wondrous, a world of surprises and falls leads. At least by accurate German standards. So one time we got so lost, we ended up at a parking area and decided to spend the night there. We slept in the vehicle, our dog slept outside.
Another thing to keep in mind is that my mother is rather paranoid and has very light sleep. In deed, she objected to sleeping in an parking area out of fear that something might happen. Criminals ganging up on us or something like that. She even made my farther go take a round to have a look at a car on the same parking area. He reported that there was just some guy making out with a gall. My mother being my mother, she stayed restless regardless.
In the middle of the night, she heard people moving around our camper vehicle. And she noticed our Wolfhound, showing his shiny teeth and making sounds of an unmistakably threatening nature. The people went gone and the night passed.
Later I got to know about German reports concerning Italian gangs who would pump gas into camper vehicles on parking areas in the middle of the night, gas which would render the inhabitants unconsciousness, and who then would consequently rob the vehicles of everything worth to be robbed.
Long story short point: Dogs can be actual full-fledged buddies which will accompany you through thick and thin. Cats are ... pets.
Also, get yourself wolfhounds. They are the most awesome dog species to ever honor this earth with their presence.
Sadly, they don't grow very old though. (7 years is rather usual, 9 years really really old)
edit: another cool story about our awesome wolfhound: Once my family had rented a kind of wood cabin when we went to holiday in the Czech Republic. Somehow, our dog didn't like it. I don't remember why, but for some reason, he really needed to get into the cabin. But apparently it seemed very suspicious or rather scary to our dog and he refused to enter. And when he refused and decided to stay where he was, there was little my mom could do about it (the rest of the family was gone some place). Like a rock and that was it. So doing all she could, pulling, screaming, whatever - my mother got desperate and sit down and started to cry. What does the dog? He moves forward towards here and then walks into the cabin just like that. I'd like to believe that he did it for my mother when he saw how sad she was.
