If you want to reduce your dog's discomfort with the pet hair dryer, then you must gradually desensitize the dog to the pet hair dryer.

You need to give your dog some necessary desensitization exercises. Depending on how scared your dog is from the hair dryer, you can adjust the level and duration of desensitization. For example, listen to the sound of the hair dryer for 2 to 3 minutes a day, 2 to 3 times a day, this process may last for days or even weeks.

Since dogs' hearing is much better than ours, they are quite sensitive to noise. Remember the principle of "slow down the training process" rather than rushing for success.

To get started, you might consider placing cotton balls in your dog's ears, or using ear protection devices designed specifically for dogs. But you should never put the cotton ball in the ear canal, and remember to remove the cotton ball from the dog's ear after training. Do this slowly until one day you will find that your dog is no longer so sensitive to hair dryers.
