The heat from the dryer comes out while you're combing your dog. That's why using this product drys your pet's hair so fast. It's small and quite easy to use. Admittedly, the handle part is thick however, it houses the heating element. Frankly, it's no big deal at all. It's not big and intimidating, so it won't freak your pet out. As well, it's not as noisy as a hairdryer. Our poodle is pleased, as he's the boss and we do what he says. I hope you enjoy it as much as we do.
