Abstract |
To emphasize the effects of group- and single housing of kennelled dogs, the behavior of 211 dogs in two German animal shelters was tested and observed. After being placed, 197 of the dogs' new owners were interviewed.
Although 51% of the German animal shelters already keep dogs in groups, there is strong prejudice against group housing because of the fear of fights. This study demonstrates that this apprehension is unfounded. Ninety-one percent of the social confrontations between dogs housed together were settled by the use of behavioral rituals. Keeping dogs in groups, furthermore, leads to a significant reduction in noise emission (p<.001). Group housing fulfills the dog's need for social interaction and the need to move. Dogs that were housed in groups displayed a closer human-animal relationship (80%) than those that had been kept individually (43%). A high percentage of individually housed dogs suffered from behavioral problems (31%) and 10% developed stereotypes. The percentage of behaviorally disturbed dogs observed in group housing was 11%, and stereotyped forms of behavior did not occur. Dogs who had been kept in groups were, on average, placed within 10 days, and were returned to the animal shelter less often (9%) compared to those housed individually (25%). Dogs that were housed separately needed an average of 17 days to be placed. Even after being placed, there is a correlation between the animal shelter's type of housing and the dog's behavior. Within four weeks after picking up their pet, 88% of the owners of dogs that had been housed individually complained of problems compared to the owners of the dogs that had been kept in groups, 53% of whom were completely satisfied with the adoption.
Despite the fact that these results might be influenced by the small number of shelters examined, the study leads to the conclusion that keeping dogs in groups is a suitable alternative for dog housing in animal shelters and, for the animals' welfare, is preferable to individual housing. |

Abstract |
Social bond analysis is of major importance for the evaluation of social relationships in group housed horses. However, in equine behaviour literature, studies on social bond analysis are inconsistent. Mutual grooming (horses standing side by side and gently nipping, nuzzling, or rubbing each other), affiliative approaches (horses approaching each other and staying within one body length), and measurements of spatial proximity (horses standing with body contact or within two horse-lengths) are commonly used. In the present study, we assessed which of the three parameters is most suitable for social bond analysis in horses, and whether social bonds are affected by individual and group factors. We observed social behaviour and spatial proximity in 145 feral horses, five groups of Przewalski�s horses (N = 36), and six groups of feral horses (N = 109) for 15 h per group, on three days within one week. We found grooming, friendly approaches, and spatial proximity to be robust parameters, as their correlation was affected only by the animals� sex (GLMM: N = 145, SE = 0.001, t = �2.7, p = 0.008) and the group size (GLMM: N = 145, SE < 0.001, t = 4.255, p < 0.001), but not by the horse breed, the aggression ratio, the social rank, the group, the group composition, and the individuals themselves. Our results show a trend for a correspondence between all three parameters (GLMM: N = 145, SE = 0.004, t = 1.95, p = 0.053), a strong correspondence between mutual grooming and friendly approaches (GLMM: N = 145, SE = 0.021, t = 3.922, p < 0.001), and a weak correspondence between mutual grooming and spatial proximity (GLMM: N = 145, SE = 0.04, t = 1.15, p = 0.25). We therefore suggest either using a combination of the proactive behaviour counts mutual grooming and friendly approaches, or using measurements of close spatial proximity, for the analysis of social bonds in horses within a limited time frame. |

Abstract |
An individual's positive or negative perspective when judging an ambiguous stimulus (cognitive bias) can be helpful when assessing animal welfare. Emotionality, as expressed in approach or withdrawal behaviour, is linked to brain asymmetry. The predisposition to process information in the left or right brain hemisphere is displayed in motor laterality. The quality of the information being processed is indicated by the sensory laterality. Consequently, it would be quicker and more repeatable to use motor or sensory laterality to evaluate cognitive bias than to perform the conventional judgment bias test. Therefore, the relationship between cognitive bias and motor or sensory laterality was tested. The horses (n = 17) were trained in a discrimination task involving a box that was placed in either a “positive” or “negative” location. To test for cognitive bias, the box was then placed in the middle, between the trained positive and negative location, in an ambiguous location, and the latency to approach the box was evaluated. Results indicated that horses that were more likely to use the right forelimb when moving off from a standing position were more likely to approach the ambiguous box with a shorter latency (generalized linear mixed model, p < 0.01), and therefore displayed a positive cognitive bias (optimistic). |
