title: Faecal corticosterone levels of dogs relinquished to a shelter in Japan.
abstract: This study investigated the baseline level of faecal corticosterone in dogs relinquished to a shelter and compared changes in it caused by social events that dogs experienced. Faecal corticosterone was measured to assess the average stress levels of dogs that depend on the actual conditions of the shelter. One category of subject animals was dogs relinquished by their owner or stray dogs who were penned in a group (group RG) or caged individually due to their incompatibility (group RI), and the other category was demonstration dogs kept for dog training classes (group DT) and petting activities held in welfare facilities for the elderly and in elementary schools (group DP). While the number of dogs that were included in groups RG and RI fluctuated almost daily, the demonstration dogs were kept together for three months. The average level of faecal corticosterone was significantly higher in group RG than in groups DT and DP. The level of group RI was also relatively high, but the difference from the other three groups was not statistically significant. Faecal corticosterone concentrations of groups DT and DP rose somewhat from the baseline levels on the day after social service activities. The results of this study reaffirm that temporarily relinquished and socially unstable dogs especially suffer a certain level of stress in a shelter.
