Airedale Terrier - The Cat of Dogs
People call them the king of the terriers, but Airedales should be called the king of the assholes. There is simply no worse dog on earth. And they really are the cat of dogs - they hate you, and will be forthcoming about their hatred. They will hate you right to your face and they will totally ignore you at the worst possible time and you'll want to hit them so badly.
If you already own an Airedale Terrier, I strongly suggest you commit suicide right now. If you do, however, make sure you kill your dog first.
Okay that was a joke. Don't kill your dog, even if it is the worst dog in the world. But do kill yourself for being so stupid as to shell out hundreds of dollars for a pure-bred pile of shit. Next time go to the local shelter - it's cheaper and you can get a sweet adult dog who will love you for the rest of its life. Seriously, and I have gobs of experience so you can trust me on this, mixed-breed shelter dogs are much better companions on average than purebreeds from a kennel. They've been through some bad times, and that builds character - just as it does in humans. Kennel dogs are raised to think they're champions, so they act like pricks. I'm totally serious when I say this. Plus, by getting a shelter dog, you might just be saving a life.
