Welfare in a shelter dog rehomed with Alzheimer patients

This study evaluates whether a shelter dog could be rehomed successfully into a facility for people suffering from Alzheimer's disease (AD). The goal was to assess the effect on animal welfare of this form of pet ownership and of individual sessions of animal assisted activity (AAA) with some pre-selected patients. After the enrollment of a suitable shelter dog, the dog was introduced gradually into the facility. Upon adoption, the dog's welfare was monitored during the first 6 months by integrating indirect assessment (18-item questionnaire) with direct observations of behavioral and clinical responses (31-item score system table), and with an assay of hormonal changes. Only descriptive statistics were done on the questionnaire data. The findings suggest a progressive positive integration into the new environment. The qualitative data using direct observations were analyzed with the Spearman Rank order correlation test. Some data showed significant variation during the period of observation, suggesting a gradual reduction of the dog's stress during AAA sessions. The hormonal trend, especially for cortisol measured in hair, seemed to correlate with the clinical and behavioral findings.
