Is your dog afraid of fireworks? The best way to teach a dog that fireworks is nothing to worry about, is to train with them as puppies.
Watch me how i am trying to prepare the puppy for the upcoming New Years Fireworks. The older the dog is the less volume and the most distance to the noise is necessary. Once the dog gets used to the sound, get the noise closer, or turn the volume up a little. Take it slow and easy, and you are going to be successful.
Let me know in the comments below how it worked for you.
