Agressive puppy Biting ...

I am a new member and need some advice on my 10 week old Staffy called Berlin ...the breeder separated him from his mom at 5 weeks and sold him to us at 7 weeks ..
We followed everything by the book about his biting ..but as time as gone on his biting as got worse ..and no matter what we do, he refuses to respond ..he just keeps going and going ..my arm is really sore ..where he keeps attacking ..we have tapped his nose ..but he snarls and growls and flys at us ..and sinks his teeth in reallly hard ..and wont let go ..if my fiance picks him up to put him in his bed ..he wiggles like a worm trying to bite his hands ..the more we say no the more he gets to bite ..and the cats are really getting it now too ..I love him to bits and need some advice as why is he so agressive , its stopped being enjoyable as be cant stroke him or anything as he bites so much ...

Hi and welcome from me and daisy :-)
He is still young and will learn, you just need to be patient and consistent. I rely found the yelp and ignore method worked for me.

Hi & welcome.

Can you tell me what food he has & how often? Also, what sort of exercise & training does he get?

Sorry for all the questions!
