Next Level Dogs

I listen to the podcast weekly & am a huge fan! I'm a fairly new trainer in VT. I had a question regarding a long down as negative punishment. I have a pit bull that I would like to try this with since he likes conflict & gets more turned on with physical punishment. Where do you make the dog do a long down if they like the crate, or if once you remove them from the stimulus they calm down fairly quickly & don't see a long down as a negative punishment. I feel like I do this but he doesn't care. I rely on management, structure, exercise & tug which has helped a ton, but not sure I'm handling it right.
Thanks!

I would down them at the occurrence. The goal is to effect their memory of the event. If you remove them from the event.... THEN down them..... It doesn't effect the memory. If that makes sense?
The deal is, that it is stressful to down in that situation. And will likely take some insistence. So... I'd avoid using it as a go to training modality. But.... As an emergency training scenario it is a way to make a teachable moment out of a shit show.
