CHRI included 4 subject dogs, all Siberian Huskies from 1 year of age to approximately 6 years old. One Handler per dog, each Human/Canine Team were together for 24 hours per day for a total of eight 24 hour periods, sequentially. Each dog was cared for by one handler, and in the possession of that handler the entire eight day sequence. None of the dogs or handlers had ever met before, and there were no preconceptions of each dog. Dogs were observed for structural, musculature and behavioral characteristics, aberrations and anomalies.
