My dog, who is 4.5 years old, hates the vacuum cleaner - STILL. I sweep, literally, every day, and he still attacks the vacuum cleaner repeatedly. He never gives up. So, when I am vacuuming, I have the kids yelling, Mayhem is yelling, "STOP," and the dog is trying to bite the throat of the vacuum.
How long does it take for a dog to get used to the vacuum, anyway? Also, it is actually a funny thing to watch (if it were not so annoying). Therefore, I took a video of it, and will have it up in the next couple of days - keep a look out!
