My 9 week olds love it when I bring them treats to snack on. My question is that when the treats are gone, they jump in my lap & love to peck at my clothes & scratch on my shoes. Sometimes they peck at my ankles...it hurts!!! Why are they pecking at me???? They are all girls. I'd like for this behavior to stop before they draw blood. Any advice or are they trying to eat me alive?!?
