As they say, a dog biting a man is not news. A man that bites a dog is news. So, this is news. From Luke Shearer in the U.K:
It happened so quick. We were walking to cut my grandma’s hedge so luckily we had some shears with us. The dog came and jumped at Sky’s neck, and it was life or death for my dog, so I just reacted and hit it with what I had. My dad was hitting it with his walking stick but that didn’t work, so I stabbed it four or five times in the spinal column, but it kept coming. I jumped on it and started biting its face until it let go.
