Grips Needles

My dog bites?
I have a 9 week old puppy and she is very intelligent (for example, she goes through the dog door when she has to use the bathroom and is 95% potty trained and have an accident from time to time), but bites like a tight grip with small hands in it and I dont know how to stop her and know she is just a puppy and that is what they do, but I want to stop young people if they do not grow out of it. She also has a lot toy, it is only when I hold her bite her ear or cheek or chin ext when she is on the ground to chew on a toy and then check out my foot and go for it and chew it or hand. So, does anyone know how to stop their young?
You should start to be the leader of the pack and take control. worked with my nieces puppy next week. First, sat beside him and without saying anything to his awakening, I put my hand on his shoulder and said "down." Reinforce and maintain hand there. She squirmed for a short time (maybe 1 / 2 – 1 minute). Once relaxed and calmed down, then I rubbed her back. Simply affection when she is calm. She finally understands! Cesar Millan (The Dog Whisperer man) has videos and books that you can buy at your website or stores. They are very useful to understand why dogs do what they do!
