Two pit bull puppies at once!

Hi, we've got two littermates, boy/girl, at 6 weeks, they're 7 weeks now, starting puppy cl$#@! in 3 weeks (trainer going on vacation)..my SO has had pits before, I've had lab mixes..am lucky to be a stay-at-home girl so MUCH time and attention as needed...they're crated together...it's snowy here and they're so young I carry them out to 'go' and reward them at site, so far pretty good, considering their age! They get some free play time after going out and afterwards sometimes crash on their dog bed, sometimes they go into the crate, sometimes I put them in the crate...Any tips on leash training, before cl$#@! start...?

thanks!
