As the other's have said it will only confuse your pup by trying different things,how long have you tried these things for before switching to another method?

We stuck to one method only it took a good few months but it paid off,you won't see results overnight it may take a good few months.

What I mean't was because this puppy is getting confused and your not sticking to one method you will have a puppy that you can't do anything with,totally out of control,with behaviour issues that later on may need rehoming,or a dog that bites a person or child due to not training correctly.

Tyler was a nightmare for biting,feet,hands,you name it,we replaced our hands feet etc with toys if he carried on,we stood up and totally ignored him,till he'd calmed down,the link Jackson posted is good.
Don't forget your puppy will also be teething and will need something to chew on.Kongs frozen are good.
Jackson's post above is also good advice again so is the link.
