He is about 2 months and 2 weeks... he born on December 05 2011
He bites our leg I think it is just play bites but will it continue?

Yeah,it will not continue biting when it's older cause my BFF had a Rottweiler and that'sthe same with her pup! Now it's an adult and it had many "biting" pups! ROFL!

It isn't just a Rottie thing, it is a puppy thing. You have to teach him not to bite. Otherwise the behavior will continue. You have a cute little pup who is going to grow into a an intelligent and powerful adult. Don't allow behaviors now that you wouldn't want in a full grown dog.

Yes, it is play, but you are not a toy. When he starts biting, give him the command that you want to use to say 'stop it', then distract him with a toy he can bite. Give him lots of praise when he plays with the toy. Another method is 'yelping' and moving away like a litter-mate would. I prefer that one for hand nipping.

Do you have the ability to make a pen (or safe room) for 'time outs'? If he continues, without fuss put him in the pen for a minute or two (lengthen the time as needed) and ignore him. You want to give him as little attention as possible when he misbehaves. Let him out. He will come to understand that being rough means he doesn't get attention or his playmate.

If you are crate training him, do not use it for time outs. You want him to see it as a safe bed instead of a jail. The same thing goes for putting him outside. It should be for going potty and play, not for punishment.

Make certain you have toys he can chew on. One brand that does well with strong chewers is Kong and they make several types that hold treats which encourages the pup to chew on them and not you or your stuff. Teething is right around the corner and you want to be prepared.

Teach him how to play appropriately with you. How you play with him now will determine how he plays with you when he is a ninety to one hundred pound adult. Know your limits and teach them to him.

Start teaching him basic obedience through play. Teaching him to mind his manners to get what he wants: Hold up a toy and have him figure out how to get you to give it to him. When he sits, he gets the toy.

I know I speak only for myself but I think our pet/dog experts will agree. Thank you for asking for advice before the behavior and the dog get out of hand. If there is anything else we can help with to get you both off to a good start on your lifetime together, please feel free to ask.

Congratulations on your new family member and may you have many wonderful years together.

He will continue to be mouthy when he is older. Yes it is a puppy thing, but during puppyhood is when you teach what is allowed and what isn't.

You need to have him stop biting you little.. It's much harder, and hurts much worse, if you wait until he is older to teach him manners. It is never OK to bite skin or clothes.. doesn't matter what the age is... Its not cute.

We do the "ouch" method.
When the puppy bites I squeel "ouch" in a high pitch voice to mimic the sound of a dog yelping, then I just stand up and walk away from the puppy.

Come back once the pup has calmed down and start playing with a toy, encourage the pup to bite the toy, but the second those teeth land on skin or clothing, repeat the "ouch" and walk away.
