Ok .. you need to slow down a bit.
Folks always seem to come up with "creative" spins on "Place" that I never anticipate?? Crate is not "Place" your going to confuse your dog and you
will lose the whole benefit of "Training" Place. And the goal of a "properly trained "Place Command" is at least two hours.
In the real world ... if you have a dog that understands a properly trained "Place Command," you can point at a spot and say "Place." The dog won't move from that spot until you release him. That is how it works. If your using "Crate as Place" you can't do that ... if there is no "Crate???" Your dog will have no idea what your talking about??? For train Crate I'd suggest per JG ... "Kennel Up"
You can work on "Place" indoors, use throw rugs around the house. Guide the dog into position with a drag leash if need be (a short leash with no handle to get caught up on furniture) or you can use a real leash but don't leave it on him indoors if your not training. Tell the dog "Place" let him stay for a few minuets guide or point to another throw rug and say "Place." Build up time two hours in one spot is the "GOAL."
In the real world you could take your dog over to a friends house, throw a mat on the ground and say "Place." The dog stays there "regardless of distractions" until you release him. The dog understands, he needs to chill because he is going to be here for awhile.
And ... yes "Place" seems to cause a lot of confusion that I don't understand myself?? But a part of it is because it "looks" similar and functions "similar to a "Stay." I heard Jeff Gellman say "he no longer teaches "Stay" because "Place" serves the same function.
I suppose, ... I tend to disagree. I train both to me "Stay " means don't move! If I said "Stay"my Struddell (White Boxer) would freeze like a statue! I don't expect her to remain like that for two hours! With "Place" a dog is free to move about that "Spot" he just can't leave it. So there is a difference as I see it.
And the "Down" thing ... the command is "Down" one word not two, it's a subtle difference but "Down" once properly taught is also an emergency command, it can stop forward motion "Now!" It's pretty hard to get "Lay Down" out if you find yourself in a "Crap Happens" situation, the one second difference between "Lay Down" and "Down" ... could cost you your dog ... so change that to one word "Down."
The Choke Chain and the SLL ... hmm never thought about it?? I suppose one could view a SLL as a large version of a Choke Chain??? If used improperly they both can casue damage. The primary difference (besides size and material, is that an "actual, SLL has the little tab thing that positions the SLL sung and high. If your working with a dog that is not used to walking properly ... that postion of the SLL (high and snug) tells them hmm something is different here???
I've found that most dogs get with the program right quick! Usually less than 4 minutes. I did have one "Pitty" that did not much care for the SLL ... he was not a 4 minute "doggy" nor was he one you'd want to yank on! He did the whole sit and won't move and then got over that and did the rear up on the hind legs thing! Sigh .. I waited him out and got on with the program a first time experiance for me. Having a dog put up that much of a fight.
Usually they struggle a bit .. get nowhere with that and then sit and look at me for directions and then I say ... "OK" ... let's go. And with a real SLL you'll find that it will fall down, the tab doesn't really stay keep it snug but ... it really does not matter, once you've made your initial point. But if on your walk you see, what may or may not be an issue?? You stop reposition t,he SLL so that is snug again and your ready for a slight tug sideways if needed.
And the straight back thing?? Yeah unless your training an "attack dog???" That's always going to be a lose! It's still a"slight tug sideways" and if the dog goes over the top ... you've lost, turn around and walk away or change your intended direction and try again or don't. You need to "communicate" with the dog before he goes over threshold if he's over the top you've lost that round. And it is a slight tug just enough to move him sideways and let him know "your still there." And yes if the dog goes sideways then yes you go sideways in the opposite direction. The goal however is to catch the dog before that happens
Did I get everything??
