You might be cleaning a little extra around the house these days, and have noticed that every time you pull out the vacuum cleaner your dog runs into another room. Have you ever wondered why your dog is scared of the vacuum? Is it the loud noise, the moving of furniture or the flurry of activity that often accompanies vacuuming? Or is it something that they can perceive that you just can't?
Dogs' fraught relationship with vacuums is well-known — but few of us truly understand the reason why. In this piece, we'll explore the answer to the question: Why are dogs scared of vacuums? We'll also dive into training techniques to help your dog better tolerate the use of this household cleaning tool.
Why Are Dogs Scared of Vacuums?
More often than not, when vacuums surface, dogs exhibit fear-driven behaviors such as trembling, hiding or barking at (or attacking) the vacuum, to name a few. But why? At the core of the issue are two basic reasons:
1. They're Noisy
The verdict on exactly how powerful dogs' sense of hearing is may still be out — but it's undeniable that in certain cases, dogs are able to detect sounds that even the sharpest human ear cannot hear. The American Kennel Club reported, "The average adult human cannot hear sounds above 20,000 Hertz (Hz), although young children can hear higher ... Dogs, on the other hand, can hear sounds as high as 47,000 to 65,000 Hz." What's more, dogs can also detect very soft sounds at high frequencies. So, considering a dog can hear sounds at lower decibels that humans (below 0dB), imagine how loud a vacuum cleaner is that often registers around 75dB, according to Yale University.
Now consider your vacuum, which emits many high-pitched sounds. To a dog who may be detecting sounds we can't hear, that racket could become too much to handle — especially if it catches them by surprise.

2. They're Smelly
Dogs' sense of smell is also powerful. While you might not realize it, your vacuum is kicking up a lot of unusual smells that your dog can detect. You might only smell the warm scent of a freshly vacuumed living room, but your dog will able to sense dust and old particles that had long since settled under your couch, according to MSN . Given that dogs rely so heavily on their sharp senses of smell, it's easy to see why they get anxious.
