Ok, so over the last week or so we have been struggling with Presley (13.5 wks) and her biting hands. She will not let you pick her up if shes playing or running. She will instead lunge at your hand and bite. I have tried to curb this by telling her BED and closing her in her crate for a little bit. When I let her out, she immediately does it again. And she WILL do it, until shes tired. Then she lays down and is a lasy litle turdmonster. But even then, if I get my hand near her head, she acts like a lazy nipping turd. I have tried giving a light tap and a sharp no, but I can rarely get the tap
