  1. Investigating the Role of Prolactin as a Potential Biomarker of Stress in Castrated Male Domestic Dogs

    Full-text: Available

    | Contributor(s):: Jara Gutiérrez, Angelo Gazzano, Federica Pirrone, Claudio Sighieri, Chiara Mariti

    Prolactin has been recently regarded as a potential biomarker of both acute and chronic stress in several species. Since only few studies until now have focussed on domestic dogs, this study was aimed at evaluating whether prolactin, cortisol and stress behaviour correlated with each other in...

  6. Use of behavioural and physiological responses for scoring sound sensitivity in dogs

    Full-text: Available

    | Contributor(s):: Carla Caroline Franzini de Souza, Daniel Penteado Martins Dias, Raquel Nascimento de Souza, Magda Alves de Medeiros

    Sound sensitive dogs have exaggerated responses to sound stimuli that can negatively impact the welfare of the dog. Behavioural reactions combined with the response to sound involve a marked autonomic imbalance towards sympathetic predominance and release of cortisol. The purpose of the present...

  7. The effectiveness of Dutch Cell Dogs in correctional facilities in the Netherlands: a study protocol of a quasi-experimental trial

    Full-text: Available

    | Contributor(s):: Gerdien Schenk, Hanne M. Duindam, Hanneke E. Creemers, Machteld Hoeve, Geert Jan J. M. Stams, Jessica J. Asscher

    Background Many former inmates recidivate, resulting in high costs for societies worldwide. Evidence based treatment practices may not work in prisons, due to detainees’ lacking motivation, impaired well-being, and an unsafe group environment. One attempt to improve social group climate...

  8. Oxytocin and Cortisol Levels in Dog Owners and Their Dogs Are Associated with Behavioral Patterns: An Exploratory Study

    Full-text: Available

    | Contributor(s):: Maria Petersson, Kerstin Uvnäs-Moberg, Anne Nilsson, Lise-Lotte Gustafson, Eva Hydbring-Sandberg, Linda Handlin

    We have previously shown that dog–owner interaction results in increasing oxytocin levels in owners and dogs, decreasing cortisol levels in owners but increasing cortisol levels in dogs. The present study aimed to further investigate whether oxytocin and cortisol levels in the previously...

  9. Cortisol and Secretory Immunoglobulin A Response to Stress in German Shepherd Dogs

    Full-text: Available

    | Contributor(s):: Ivona Svobodová, Helena Chaloupková, Roman Koncel, LudÄ›k Bartoš, Lenka Hradecká, Lukáš Jebavý

    The aim of the study was to determine whether cortisol and secretory Immunoglobulin A (sIgA) could be used as an indicator of acute stress in both young and adult dogs. Seventeen German shepherd puppies were exposed to the Puppy test (challenge test) at the age of seven weeks. This test has...

  10. Evaluation of effects of olfactory and auditory stimulation on separation anxiety by salivary cortisol measurement in dogs

    Full-text: Available

    | Contributor(s):: Yoon-Joo Shin, Nam-Shik Shin

    Separation anxiety (SA) is a serious behavioral problem in dogs. In this study, salivary cortisol was studied to determine if the owner's odor or voice could reduce SA in dogs. Twenty-eight dogs with SA were divided into three groups: group 1 (control), group 2 (with owner's clothes...

  11. The Effectiveness Of Enrichment Programs For Dogs In An Animal Shelter

    | Contributor(s):: Pamela Perry

    Dogs (N = 108) in an animal shelter received one of four enrichment programs: twice daily walking alone (walking) or in combination with a daily fooddispensing toy (toy), a daily session of standardized human contact (petting), or daily obedience training (obedience). We evaluated the effects of...

  12. Human interaction and cortisol: Can human contact reduce stress for shelter dogs?

    | Contributor(s):: Crista L. Coppola, Temple Grandin, R. Mark Enns

    Animal shelters are an extremely stressful environment for a dog, most specifically due to social isolation and novel surroundings. The stress response of dogs housed in this environment may be alleviated through human interaction shortly after arrival. During their second day in a public...

  13. A case study: fecal corticosteroid and behavior as indicators of welfare during relocation of an Asian elephant

    | Contributor(s):: Laws, N., Ganswindt, A., Heistermann, M., Harris, M., Harris, S., Sherwin, C.

    This study was a preliminary investigation of an enzyme immunoassay for measuring fecal glucocorticoid metabolites in a male Asian elephant (Elephas maximus) by investigating changes in behavior and cortisol metabolite excretion associated with a putative stressful event. The study collected...

  14. A combination of behavioral and physiological indicators for assessing pig welfare on the farm

    | Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.

The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...

  16. Circadian rhythm of salivary cortisol in Asian elephants (Elephas maximus): a factor to consider during welfare assessment

    | Contributor(s):: Menargues, A., Urios, V., Liminana, R., Mauri, M.

    Elevated glucocorticoid levels during an extended time period might be a stress indicator in nonhuman animals. Therefore, knowledge of the circadian pattern of cortisol secretion is very important to correctly interpret data obtained for welfare assessment of animals in captivity through salivary...
