Another thing you can do it get a slim fast drink, make sure you drink it, rins the can out really good and Put 25 or so pennies in it, tape the top so the pennies will not come out and take the slimfast wrapping off so you just have a shinny can.
When ever the dog bits you give the can a little shake (They can't stand the noise). and make him go to time out. Also if the dog get up from time out make him go back untill you let him up.
