Description : Do dogs know if they're biting something that is alive?
Last Answer : Oh yeah they do. My brother's dog would nip a little in the house. Mostly playful. I went into his pen one day. He didn't like that at all. He chewed on me hard. I didn't back down and ... doing. Both arms were scratched up bad and the next day they were black and blue from my wrist to my elbow.
