Yes. The United States, as noted, is very well advanced in research and the benefits related to service dogs. Currently, the United States Department of Veterans Affairs service dog veterinary health benefit provides service dogs to veterans for issues relating to hearing, vision and mobility. Based on their five-year study, they're looking right now at what changes they might want to pursue in the future. That's what we're closely monitoring.
I'll ask Nathan to add some additional context from a research perspective on that issue.
