  3. The Untrained Response of Pet Dogs to Human Epileptic Seizures

    | Contributor(s):: Powell, N. A., Ruffell, A., Arnott, G.

    Epilepsy is a debilitating and potentially life-threatening neurological condition which affects approximately 65 million people worldwide. There is currently no reliable and simple early warning seizure-onset device available, which means many people with unstable epilepsy live in fear of...

  4. Still “Serving” Us? Mutualism in Canine Scent Detection of Human Illness

    | Contributor(s):: Eason, Fenella

  5. Olfactory Generalization in Detector Dogs

    Full-text: Available

    | Contributor(s):: Ariella Y. Moser, Lewis Bizo, Wendy Y. Brown

    Generalizing to target odor variations while retaining specificity against non-targets is crucial to the success of detector dogs under working conditions. As such, the importance of generalization should be considered in the formulation of effective training strategies. Research investigating...

  6. The semiotic canine: scent processing dogs as research assistants in biomedical and environmental research

    Full-text: Available

    | Contributor(s):: Gadbois, S., Reeve, C.

    The use of dogs in biomedical diagnosis, detection and alert as well as for the search and monitoring of species-at-risk is an emerging field of research. Standard practices are converging towards models that are not necessarily consistent with the well established field of (animal)...

  8. Dogs can detect the individual odors in a mixture of explosives

  9. Use of a habituation-dishabituation paradigm to assess gilt olfaction and sensitivity to the boar pheromone

    | Contributor(s):: Aviles-Rosa, Edgar O., McGlone, John J., Hall, Nathaniel J.

    Olfactory stimuli have been used to reduce stress in weaning pigs and induce sexual behavior in sows. Despite the importance of olfaction in pig production and behavior, there is no simple method to assess pig olfaction. Thus, the objectives of this study were: (1) to evaluate the use of an...

  10. Olfactory-based interspecific recognition of human emotions: Horses (Equus ferus caballus) can recognize fear and happiness body odour from humans (Homo sapiens)

    | Contributor(s):: Sabiniewicz, Agnieszka, Tarnowska, Karolina, Świątek, Robert, Sorokowski, Piotr, Laska, Matthias

    Emotional recognition has been demonstrated to occur between members of different species. However, the majority of studies on interspecific communication of emotions so far focused on the senses of vision and hearing while the contribution of the sense of smell has rarely been studied in this...

  11. Behavioral and Perceptual Differences between Sexes in Dogs: An Overview

    Full-text: Available

    | Contributor(s):: Anna Scandurra, Alessandra Alterisio, Anna Di Cosmo, Biagio D’Aniello

    In this paper, we review the scientific reports of sex-related differences in dogs as compared to the outcomes described for wild animals. Our aim was to explore whether the differences in male and female dogs were affected by the domestication process, in which artificial selection is the main...

  12. Olfactory Enrichment in California Sea Lions (Zalophus californianus): An Effective Tool for Captive Welfare?

    | Contributor(s):: Samuelson, Mystera M., Lauderdale, Lisa K., Pulis, Kelly, Solangi, Moby, Hoffland, Tim, Lyn, Heidi

    In the wild, California sea lions (Zalophus californianus) are exposed to a wide variety of sensory information, which cannot be replicated in captive environments. Therefore, unique procedures are necessary for maintaining physiological and psychological health in nonhuman animals in captivity....

  13. Explosives detection by military working dogs: Olfactory generalization from components to mixtures

    | Contributor(s):: Lazarowski, Lucia, Dorman, David C.

    The training of scent detection dogs using samples of explosives or their chemical precursors is a well-established and documented practice. However an area of canine odor detection that remains under-studied regards a trained dog's perception of an explosive odor when more than one odorant is...

  14. The effects of three types of environmental enrichment on the behaviour of captive Javan gibbons (Hylobates moloch)

    | Contributor(s):: Gronqvist, Gabriella, Kingston-Jones, Mark, May, Adam, Lehmann, Julia

    Studies on a large variety of species have shown that enrichment can be successfully used to encourage natural behaviours, to decrease rates of abnormal behaviour and to improve welfare in captive animals. However, whether or not a specific enrichment device is enriching depends on the species...

  15. Enrichment for captive tigers (Panthera tigris): Current knowledge and future directions

    | Contributor(s):: Szokalski, Monika S., Litchfield, Carla A., Foster, Wendy K.

    Environmental enrichment is a common approach for addressing stereotypic behaviour in captive animals. Like many big cats, tigers (Panthera tigris) are renowned for their stereotypic pacing, yet relatively little is known about optimal enrichment for this species. Given the large proportion of...

  16. Differential responses of captive southern hairy-nosed wombats (Lasiorhinus latifrons) to the presence of faeces from different species and male and female conspecifics

    | Contributor(s):: Descovich, Kristin A., Lisle, Allan T., Johnston, Stephen, Nicolson, Vere, Phillips, Clive J. C.

    The southern hairy-nosed wombat (Lasiorhinus latifrons) appears to use scent marking, including defaecation, for social communication in the wild. This premise assumes that the receiver wombat is able to distinguish between faeces from different sources. To examine this theory, four types of...

  17. Behavioural analysis of solitary versus socially housed snow leopards (Panthera uncia), with the provision of simulated social contact

    | Contributor(s):: Macri, Alaina M., Patterson-Kane, Emily

    Activity budgets of 18 captive snow leopards were analyzed in order to assess the behaviour of cats housed singly versus those housed socially. Six solitary snow leopards and 12 socially housed snow leopards were compared. Pacing and activity level were used as indicators of the potential welfare...

  18. Canine Olfactory Thresholds to Amyl Acetate in a Biomedical Detection Scenario

    Full-text: Available

    | Contributor(s):: Astrid R. Concha, Claire M. Guest, Rob Harris, Thomas W. Pike, Alexandre Feugier, Helen Zulch, Daniel S. Mills

    Dogs’ abilities to respond to concentrations of odorant molecules are generally deemed superior to electronic sensors. This sensitivity has been used traditionally in many areas; but is a more recent innovation within the medical field. As a bio-detection sensor for human diseases such as...

  19. Ethanol and a chemical from fox faeces modulate exploratory behaviour in laboratory mice

    | Contributor(s):: Grau, Carlos, Leclercq, Julien, Descout, Estelle, Teruel, Eva, Bienboire-Frosini, Cécile, Pageat, Patrick

    Mice are macrosmatic animals that use olfaction as their main source of information to increase fitness; they process predator cues to assess risk, and plants and fruit cues to find nutritional resources and assess their quality or toxicity. In this study, we examined the effects of ethanol as an...

  20. Perception and emotions: On the relationships between stress and olfaction

    | Contributor(s):: Bombail, Vincent

    Adaptations to the ever changing social and physical environment are necessary, sometimes involving the stress response. Olfaction is a chemical sense allowing the detection of molecules in the air, and many species rely on it for social recognition and fundamental functions such as feeding or...
