4 month old puppy is so hyper. Runs around the house ruining and breaking things and bites everything. When we try to calm her down, she bites our hands and its deep enough to leave a mark but not deep enough for our hands to bleed. She was hyper before but not this much. Now, everytime we touch her, she goes in for our hands. We give her toys to bite but she still very much prefer our hands and its hurting. How do I teach her to calm and stay put? When training, I can barely manage to teach her to sit and then jumps on me the next minute.
