Aggressive behavior of dogs kept as companion animals: classification and influence of sex, reproductive status and breed
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
| 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
| 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...
"Who's been a good dog?" - Owner perceptions and motivations for treat giving
| Contributor(s):: White, G. A., Ward, L., Pink, C., Craigon, J., Millar, K. M.
Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year...

'Canis empathicus'? A proposal on dogs' capacity to empathize with humans
| Contributor(s):: Karine Silva, Liliana de Sousa
Empathy has long attracted the attention of philosophers and psychologists, and more recently, of evolutionary biologists. Interestingly, studies suggest that empathy is a phylogenetically continuous phenomenon, ranging across animals from automatic emotional activation in response to the...
'subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity
| Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.
In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...

A behaviour test on German Shepherd dogs: heritability of seven different traits
| Contributor(s):: Ruefenacht, S., Gebhardt-Henrich, S., Miyake, T., Gaillard, C.
In this study, genetic and non-genetic effects on behavioural traits were estimated, based on records of the field behaviour test of the Swiss German Shepherd Dog breeding club. This standardized test has been applied since 1949 and comprised the following seven traits: self-confidence, nerve...
A behavioural comparison of New Zealand White rabbits ( Oryctolagus cuniculus ) housed individually or in pairs in conventional laboratory cages
| 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 behavioural study of scrapie-affected sheep
| Contributor(s):: Healy, A. M., Hanlon, A. J., Weavers, E., Collins, J. D., Doherty, M. L.
The behaviour of 12 sheep, suspected of having scrapie, and 12 clinically normal animals from the Irish Republic was observed over a 6-day period [date not given]. Confirmation of the true disease status of the animals was made at postmortem using both histopathological and immunocytochemical...

A brief note on some possible factors involved in the reactions of horses to humans
| 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...
A brief report on aggressive interactions within and between groups of domestic turkeys ( Meleagris gallopavo )
| Contributor(s):: Buchwalder, T., Huber-Eicher, B.
Aggressive encounters and injuries due to head pecking seriously threaten the welfare of domestic turkeys and also result in economic waste within the turkey industry. The aim of this study was to investigate whether domestic turkey toms distinguish group members from non-group members and if...
