oh yes many times, I actually bit a dog once... my dog and another dog where fighting outside my house, I was 8 years old and I was scared for my dog so I tried to help him, the other dog bit my arm and I hit him several times but he didn't let go so I bit him on the back 🤣 it didn't work either. My dad came to my rescue and I only needed a few small stitches and a rabies vaccine.
