Measuring heart rate variability in horses to investigate the autonomic nervous system activity - pros and cons of different methods
Contributor(s):: Stucke, D., Ruse, M. G., Lebelt, D.
Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses....
Heart rate variability during a working memory task: does touching a dog or person affect the response?
Contributor(s):: Gee, N. R., Friedmann, E., Stendahl, M., Fisk, A., Coglitore, V.
The presence of a dog has been associated with reduced responses to stressors in several, but not all, previous studies. The presence of a dog has also been related to improved performance on some cognitive tasks. The current study was designed to evaluate the effect of touching a dog on stress...
Equine stereotypic behaviors: causation, occurrence, and prevention
Contributor(s):: Sarrafchi, A., Blokhuis, H. J.
There are strong suggestions that equine stereotypies are connected to poor welfare and a suboptimal management and/or stabling environment. Different forms of equine stereotypic behaviors have been described. Crib biting, weaving, and box walking are considered the most prevalent. Several...
Evaluating the effect of early neurological stimulation on the development and training of mine detection dogs
Contributor(s):: Schoon, A., Berntsen, T. G.
Early neurological stimulation (ENS) has been proposed to enhance the natural abilities of dogs. This kind of stimulation involves subjecting pups aged between 3 and 16 days to mild forms of stimulation leading to "stress," and is said to lead to faster maturation and better problem-solving...
Periods of early development and the effects of stimulation and social experiences in the canine
Contributor(s):: Battaglia, C. L.
It is not capacity that explains the differences that exist between individuals, because most seem to have far more capacity than they will ever use. The differences that exist between individuals seem to be related to something else. Researchers have studied these phenomena and have looked for...
Socialization of Puppies - A Marker of Their Future Behaviour
Contributor(s):: K. Uzunova, V. Radev, L. Varlyakov
An investigation on the relationship between temperament and socialization upon thedevelopment of the behaviour of the dog was carried out. The test of Queinnek was applied on10 puppies from the Dobermann and German Shepherd breeds. The temperament type of eachpuppy was determined with reagrd to...

Pain and stress in crustaceans? (Special Issue: Animal suffering and welfare.)
Contributor(s):: Elwood, R. W., Barr, S., Patterson, L.
We consider evidence that crustaceans might experience pain and stress in ways that are analogous to those of vertebrates. Various criteria are applied that might indicate a potential for pain experience: (1) a suitable central nervous system and receptors, (2) avoidance learning, (3) protective...
Assessment of mental stress in warmblood horses: heart rate variability in comparison to heart rate and selected behavioural parameters
Contributor(s):: Rietmann, T. R., Stuart, A. E. A., Bernasconi, P., Stauffacher, M., Auer, J. A., Weishaupt, M. A.
The aim of the study was to investigate whether heart rate variability (HRV) could assess alterations of the autonomic nervous system (ANS) at different levels of excitement. The behavioural and physiological responses of 20 warmblood horses to a challenging ground exercise task were studied....

Perseverative responding and the aetiology of equine oral stereotypy
Contributor(s):: Hemmings, A., McBride, S. D., Hale, C. E.
Research suggests that environmentally-induced (spontaneous) stereotypies arise from dysregulation of the basal ganglia. Basal ganglia dysfunction can also expresses itself as aberrations in learning task performance. As a result, several studies have demonstrated a strong link between...
Background to anomalous behaviour
Contributor(s):: Fraser, A. F.
Contributor(s):: Forbes, J. M.
This review deals with an animal's ability to sense foods in the environment up to the point of swallowing (using vision, olfaction, taste, texture, position and palatability), i.e., where awareness of food is clearly conscious. Then the consequences of eating at the levels of the digestive...
Exploratory study of stress-buffering response patterns from interaction with a therapy dog
Contributor(s):: Barker, S. B., Knisely, J. S., McCain, N. L., Schubert, C. M., Pandurangi, A. K.
This exploratory study builds on existing research on the physiological stress response to human-animal interactions in a non-clinical sample of adult dog-owners interacting with their own or an unfamiliar therapy dog under similar conditions. Participants were therapy-dog owners (TDO group; n=5)...
