The excessive fear of firecrackers, fireworks, thunder or other loud noises is common in dogs, and causes the animal to try to flee or hide, seek protection for his master, shake, put the tail between the legs, tumble, growl or bark from a distance.
This fear affects the mascot for the suffering endured and the risk that it could hurt them trying to escape or hide, as well as its owner because the animal can attack him when he tries to help, or result in material losses housing.
The causes of fear or phobia of loud noises that some dogs develop are varied: 1) a traumatic experience, 2) never having been exposed to loud noise when they were puppies, 3) genetic propensity to develop a fear of noise, 4) phobia triggered inadvertently by its owner.
An example of this last point. It is normal for a dog that never heard thunder startles and may even react with fear. If at that time the owner continues to behave normally and shows that nothing happens, you usually end up settling down the dog and get used to the strange noise. But if on the contrary, the owner caresses, kisses him, cuddle him, or he says things like, poor thing!
In the eyes of the dog, its owner is rewarding him for being afraid, so this behavior will be reinforced and the result is that the dog perceives that its owner also thinks it's a situation to be afraid, and also the more shaking, more coddle. So we are conditioning the response of fear in your subconscious.
