They build that trust, for sure, and that trust is the base for everything. If you don't have a solid base on how that connective piece works, it's very hard, I think, to have a service dog that's going to be functional for that veteran in any environment that they want to go into.
Can someone take an obedient dog into most environments? For sure, but an injured veteran poses a whole new circumstance, because you don't know when they're going to be triggered and you don't know what's going to cause it all the time. However, you work on the different types of regulating, the recovery things, that will help them with their dog come back to being present so that they can safely, for example, go home.
