The reason why a dog is bitten and has a big soft swollen bump is because the dog's skin is relatively loose. When bitten by another dog, the dog's bite force is relatively strong, which will cause the skin layer and muscle layer to interact with each other. After peeling off, a larger cavity will appear, and some exudate or blood will accumulate in the cavity to form a large bag. It will also cause infection due to the presence of a large number of bacteria on the dog's teeth.
