Staffordshire Bull Terrier Puppy Growling!

Question
Hi Nancy please could you help us me and my partner recently got our second staffordshire bull terrier we already have a female shes still only 10mnths old but a great dog and very well behaved we have just got a male stafford and hes now 10wks old so still very young had him a couple of weeks and after a few days or so we started to notice that he didnt like to be told off whenever we tell him NO or BAD and when we lift him or try to give him a cuddle and say put him on his back to give him a little tummy rub things like that he growls at us he doesnt show any teeth but its a scary thing we are now very worried our female didnt do this and i have never heard of a puppy growling at you before not so young anyway! Please could you tell us if this is a sign he is aggressive and things will only get worse or if its just because he doest know any better and needs time to learn?? We are training him and when we tell him of he does now go to bed bit if you do something he isnt happy with or about then he lwts you know by growling at us! When he does go to his bed after being told off he looks up at us but with his head down just like what they call puupy wleyes but i think that hes looking at us because he is unhappy and like i said because he doesnt like to be given a telling off for anuthing? Please let us know what to do i am going to take him to puppy classes once he has had his next jag but im just worried that he has an aggressive nature ans nothing will change that am i wrong is it just as hes a pup and we just need to give it time? Will he grow out of it once hes learnt do you think? Hes also very rough when playing with my female and she doesnt do anything back but he nips her everywhere and makes really vicious sounding noises while playing with her? I feel sorry for her as shes just so soft so im always telling him off when he bites her and she will squeel when he hurts her so i have to constantly tell him off for that and to play nice not hurt her. Please get back to me as soon as possible and help us we really are worried and not sure what to do wether to just continue to tell him off and possibly start to put him in his cage to also show him he has been bad is that a good idea for us to do that with him i just dont know so i would really appreciate your help and to tell us wether or not this is normal behaviour or not and what you think we should do with him. Thank you very much and i really hope to hear back from you soon Nancy. Thanks Steph.

Answer
Hi Steph,
At 10 weeks he is doing to you what he learned in the litter.  He is treating you like another puppy, pits are very competitive.  I would give it a little time and be much more forceful when he growls.  I would hold his mouth gently for a second when I say 'NO' to let him know you don't like him growling.  Tell him, "No Growl".  If this escalates to biting you will then have to put him on his side or back until he submits and becomes calm.  You only let him get up when he is totally calm and submits.  You want him to stay there when you let go, so hold him until he relaxes then slowly let go while telling him to stay.  You might have to jump back to a hold a few times until you succeed at this.
If you are afraid of him at ten weeks, you might want to exchange him for one of the other pups in the litter who is calmer.  This is something you will have to figure out for yourselves, you should be comfortable with your pet.  
You can start to be his "alfa" by teaching him to sit, stay, down, do not let him eat until he sits.  Become more comfortable with him.
As far as your female, I would separate them.  You don't want her hurt and you don't want her to get nasty.  You also don't want to be constantly correcting him when he doesn't know what he is doing wrong.  If you teach him "Leave It" , you can apply that to when he bothers her.

If you don't know how to teach "Leave it"  get back with me.
