Contributor(s): Peter L. Borchelt
Data were obtained from a total of 245 cases of aggressive-behavior problems in dogs kept as companion animals. Aggression involved barking, growling and biting behavior. For each case, a home visit of one to several hours yielded a description of the sequences of aggressive behavior and the...
Owner-companion dog interactions: relationships between demographic variables, potentially problematic behaviours, training engagement and shared activities
Journal Articles | Contributor(s): Pauleen Charmayne Bennett, Vanessa Ilse Rohlf
Many companion dogs occupy a privileged position in our society, living closely with human caretakers who go to great lengths to provide for their needs and desires. Others fare less well, being abandoned or killed, many because they are believed to exhibit behaviour problems. The aim in this...
"Bark parks" - a study on interdog aggression in a limited-control environment
Journal Articles | Contributor(s): Shyan, M. R., Fortune, K. A., King, C.
As limited-control dog parks become more popular, concerns arise about whether these parks encourage interdog aggression. Systematic observations made at 1 park in Indianapolis, USA over 72 h (between 1600 and 1830 h, 3-5 times a week) across 8 months (between March and November 2001) found that...

A behavioural comparison of New Zealand White rabbits ( Oryctolagus cuniculus ) housed individually or in pairs in conventional laboratory cages
Journal Articles | Contributor(s): Chu, L. R., Garner, J. P., Mench, J. A.
Despite their gregarious nature, rabbits used for research are often housed individually due to concerns about aggression and disease transmission. However, conventional laboratory cages restrict movement, and rabbits housed singly in these cages often perform abnormal behaviours, an indication...

A brief note on some possible factors involved in the reactions of horses to humans
Journal Articles | Contributor(s): Hausberger, M., Muller, C.
In order to investigate relationships of adult horses to humans, we developed a simple evaluation test and scores based on observations. The first reactions of 224 adult horses to the presence of an experimenter were observed and scored. All these horses belonged to the same riding school, had...
