Without knowing the extent of the injury all I can advise is to try to keep her quiet and calm and monitor for any trouble breathing or discomfort. Signs of breathing difficultly, trouble walking, dissension of the abdomen, bleeding, changes in attitude that include panting, inability to get comfortable, or any sign of distress warrant an immediate trip to the closest emergency clinic. Please see the vet tomorrow and I expect they will do a thorough exam and provide pain medication (please don’t use an over the counter without the vets ok), and antibiotics.
I’m sorry but I don’t understand what your question is? Please ask your vet about conditioning behavior training if your dog seems to be afraid.
It sounds as though your dog is fearful of the noise. With noise sensitivities, we can use desensitization and counterconditioning to acclimate the dog to the sound. We would start by playing the sound at a very low volume (low enough so the dog doesn’t have the fear response) and giving a treat about one second after the sound occurs. When we shut off the noise, the food stops. So, the dog learns that the noise predicts the food. You may need the help of a good trainer or behaviorist to do this conditioning, but the god news is that it can be very effective. We use this technique to get dogs to like all kinds of things they previously feared or disliked.
While this video doesn’t involve noise, it’s a good example of the procedure:
