You may not like trapping. Or you may have no problem with trapping as long as trappers follow the rules.
Regardless, these videos contain information that you can use — especially the second one, on releasing your dog from traps. They were made by Idaho Fish & Game, but everything in them pertains to other states as well, except maybe the wolf part.
Basic rule: Compress the springs, don't pry the jaws.
If nothing else, learn the Conibear trap, which starts at about 3:40 in the video. "Your dog is most likely to be trapped by its head or neck, so it's critical you learn how to act quickly to save your dog."
If you have any actual experience with dogs in traps, I would like to hear it. But if you just want to talk about how you want to put some trapper's head in a large-size Conibear, well, I have heard that before.
