As we mentioned, we are continuing to follow what's happening with our allies, including largely the United States Department of Veterans Affairs and the Australian Department of Veterans' Affairs, to help inform where we want to go in the future, because, as noted, there has been research done. We have worked to develop consensus for national standards, and we've made some progress, but we still need that underpinning of research to really assist with ensuring that what we're doing is the right thing for veterans.
I will ask Dr. Heber to speak to some of the issues that we see with service dogs. They assist with managing symptoms. They are not a treatment in their own right.
Dr. Heber.
