First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study looked at whether teaching military members to train service dogs can improve symptoms of PTSD, anxiety, depression, and concussion. 156 participants spent one hour twice a week working with professional dog trainers. Researchers measured changes in stress, mood, sleep, and even blood markers like cortisol. The goal was to see if this hands-on program adds benefits beyond standard care.

Exclusion Criteria: * Participants must not be younger than 18 years old or other than 65 years old at the time of consent. * Participant must not show current suicidal/homicidal plans (if the participant expresses current suicidal/homicidal plans, clearance from the participant's current behavioral health team can be provided). * Participant must not exhibit violent or psychotic behavior. * Participant must not currently or in the past month have been in an inpatient psychiatric health treatment program. * Participant must not currently have an active substance abuse disorder or been in a substance abuse program in the past month. * Participant must not have problems that limit cognitive competency to understand study procedures, including the ability to provide informed consent (e.g., severe TBI).
