The other day I visited Mr. Tan's Violin Shop to renew the rent of violin. He is such a nice guy, but his dog is huge. I opened the door and the dog was walking toward me. I am scared. But I heard from a vet, if a dog attack you, you have to bear the pain, hold the legs with each hand and move them to the opposite directions as much as you can Extremely quickly, the dog will go to trauma very quickly and die.
