when you tell my pup to sit he will and he will imediately but if you move or take a step he is right there moving with you.I have had him on pinch collar with some quick jerks of leash and sit and nothing.I have tried healing stick with pops to hind end sit and he will but as soon as you move,here he comes.I have tried with a collar on one with sit here he comes level 2- here he comes,3 a little flinch but still comes,level4 he will sit for about 3-4 seconds but then will come.(on level 4 I get very small peep out of him)Hehas been FF and trying to move to pile work and start handling soon but with him not remote sitting it is kind of hard.He is 11 mo old and will be one here in next couple of Days.
