Holy crap, that's scary. I'm guessing the dog didn't directly cause it. Look for energy healers or something; they actually can do a bit of work, and no, I'm not some wacko out in some rural town nobody's heard of. Really, try them, or look for a clairvoyant person to tell you the problem. Try putting lots of rosemary and strong herbs around the dog. Also, if the dog is supernaturally causing things and it's not just luck, killing it or getting rid of it won't help.
For specifications, how long have you had the dog, and it what proximity of time did all the disasters happen? Additionally, are you a very careless person that breaks things a lot?
