most of my dogs were trained to sit with the treat over the head thing. Electra didnt quite catch on to that one though lol she like using her paws too much. so for her I placed my hand under her chin and lifted up and pressured inward, this causes her to sit. when walking I always have her sit at street corners(well I have all of them sit, but Happy and Misty dont have to be told lol) but when otherwise training right now I try to avoid her sitting as much as possable, just because she is not the brightest bulb on the tree and I dont want her randomly sitting in the ring lol

oh and for the standing thing, with Electra I start training something kneeling or sitting and then once is solid there I slowly rise up, just so the change of postions is not so huge. Leck is the only dog I have had to do that with though, BCs are so much eaiser to train lol
