My puppy keeps biting. I know biting and nipping are normal but she seems to take it to an extreme. I take her outside multiple times a day. My family and I also take turns playing with her. For some reason, she still tries to bite me outside of play time. She has even started chewing up her puppy pads. She does chew on her toys but the moment I'm in view, she will try to bite my legs or any other place she can reach. Is there anyway of preventing this?
