  1. Canine Endogenous Oxytocin Responses to Dog-Walking and Affiliative Human–Dog Interactions

    Full-text: Available

    | Contributor(s):: Lauren Powell, Kate M. Edwards, Adrian Bauman, Adam J. Guastella, Bradley Drayton, Emmanuel Stamatakis, Paul McGreevy

    Several studies suggest human–dog interactions elicit a positive effect on canine oxytocin concentrations. However, empirical investigations are scant and the joint influence of human–dog interaction and physical activity remains unexplored. The aims of the current study were to (a)...

  2. Ocitocina sérica e comportamento afetivo de cães na interação com crianças e adultos

    Full-text: Available

    | Contributor(s):: Luelyn Jockyman

    A ocitocina tem sido usada como parâmetro para medir os laços sociais em animais. Recentemente foi demonstrado que a concentração de ocitocina aumenta em cães e donos quando interagem positivamente e, possivelmente, que na interação com...

  3. Effects Of Vicarious Equine Interaction On Anxiety And Neuromodulators

    Full-text: Available

    | Contributor(s):: Jane Camille Gray

    Human-animal interaction influences the release of neuromodulators, such as cortisol, epinephrine and norepinephrine (Beetz, Uvnäs-Moberg, Julius, & Kotrschal, 2012). No data could be located in the literature to establish a neuromodulating effect of Vicarious Equine Interaction (VEI)...

  4. Effects of Short-Distance Recreational Mushing on Oxytocin, Gastrin, and Creatinine Kinase in Sled Dogs

    | Contributor(s):: Leggieri, Leonardo Ramón, Marozzi, Antonela, Panebianco, Antonella, Gregorio, Pablo, Carmanchahi, Pablo

    A considerable increase in creatinine kinase (CK) activity and gastrin hormone due to exercise has been observed in sled dogs during endurance mushing races; however, there have been no studies on sled dogs during recreational mushing. Although oxytocin hormone is involved in social behaviors and...

  5. Effects of Human–Dog Interactions on Salivary Oxytocin Concentrations and Heart Rate Variability: A Four-Condition Cross-Over Trial

    | Contributor(s):: Powell, Lauren, Edwards, Kate M., Michael, Scott, McGreevy, Paul, Bauman, Adrian, Guastella, Adam J., Drayton, Bradley, Stamatakis, Emmanuel

    Dog ownership is often advocated for its potential benefits to human health, with changes to oxytocin and autonomic nervous system (ANS) activity proposed as possible underlying mechanisms. The aims of the current study were to a) examine the effect of two common types of human–dog interactions...

  6. Prepartum nest-building has an impact on postpartum nursing performance and maternal behaviour in early lactating sows

    | Contributor(s):: Yun, Jinhyeon, Swan, Kirsi-Marja, Farmer, Chantal, Oliviero, Claudio, Peltoniemi, Olli, Valros, Anna

    The effects of facilitating prepartum nest-building (NB) behaviour, by providing abundant nesting materials, on postpartum maternal characteristics in early lactating sows were evaluated. A total of 35 sows, approximately seven days before the expected parturition date, were housed in: (1) CRATE...

  7. Prenatal stress puzzle, the oxytocin piece: Prenatal stress alters the behaviour and autonomic regulation in piglets, insights from oxytocin

    | Contributor(s):: Rault, Jean-Loup, Mack, Laurie A., Carter, C. Sue, Garner, Joseph P., Marchant-Forde, Jeremy N., Richert, Brian T., Lay, Donald C.

    Developmental changes in response to prenatal stressors (PNS) can result in anxiety and abnormal social development in the offspring. Oxytocin (OT) reduces anxiety, whereas OT deficiencies are associated with social behaviour deficits. Hence, we hypothesized that OT could reverse some of the PNS...

  8. Nest-building in sows: Effects of farrowing housing on hormonal modulation of maternal characteristics

    | Contributor(s):: Yun, Jinhyeon, Swan, Kirsi-Marja, Vienola, Kirsi, Farmer, Chantal, Oliviero, Claudio, Peltoniemi, Olli, Valros, Anna

    Prepartum nesting opportunities may improve maternal characteristics and welfare of sows during parturition and lactation. We investigated the effects of provision of space and nesting material prior to parturition on circulating oxytocin concentrations, maternal characteristics and their...

  9. Effects of Stroking on Salivary Oxytocin and Cortisol in Guide Dogs: Preliminary Results

    | Contributor(s):: Ogi, A., Mariti, C., Baragli, P., Sergi, V., Gazzano, A.

    This pilot study aimed at investigating how salivary oxytocin levels are affected by human interaction and isolation in eight guide dogs (six Labrador retrievers and two golden retrievers; four males and four females, 21.87 +/- 1.36 months old) just before assignment to the blind person. Each dog...

  10. Salivary oxytocin in pigs, cattle, and goats during positive human-animal interactions

    | Contributor(s):: Lurzel, S., Buckendorf, L., Waiblinger, S., Rault, J. L.

  11. Re-direction of maternal behaviour in dairy cows

    | Contributor(s):: Mandel, Roi, Nicol, Christine J.

    In the milk producing industry, most aspects of maternal behaviour are discouraged, but milk production is actively maintained in the absence of the calf. The process of milk let down, is mediated, at least partly, by oxytocin, which has been shown to play a central role in facilitating maternal...

  12. The effect of a pressure vest on the behaviour, salivary cortisol and urine oxytocin of noise phobic dogs in a controlled test

    | Contributor(s):: Pekkin, Anne-Maria, Hänninen, Laura, Tiira, Katriina, Koskela, Aija, Pöytäkangas, Merja, Lohi, Hannes, Valros, Anna

    Fear of loud noises is a common welfare problem in pet dogs. Commercial treatment vests have been tested on dogs to relieve noise phobia, and peripheral oxytocin has been suggested to be one of the stress-relieving mediators. The effect of vests has not, however, been tested in a controlled...

  13. The effect of oxytocin on yawning by dogs (Canis familiaris) exposed to human yawns

    | Contributor(s):: Kis, Anna, Tóth, Katinka, Kanizsár, Orsolya, Topál, József

    Previous studies have found that human yawning is contagious to dogs, but the results are still controversial. It is also debated whether contagious yawning is a sign of empathy, and the physiological mechanisms behind this phenomenon are also unknown. Our goal was to further investigate if human...

  14. Effects of Affiliative Human–Animal Interaction on Dog Salivary and Plasma Oxytocin and Vasopressin

    Full-text: Available

    | Contributor(s):: Evan MacLean, Laurence R Gesquiere, Nancy R Gee, Kerinne Levy, W Lance Martin, C Sue Carter

    Oxytocin (OT) and vasopressin (AVP) are neuropeptides with diverse effects on social behavior, cognition and stress responses. Recent studies suggest that OT facilitates and responds to affiliative forms of human–animal interaction (HAI). However, previous studies measuring OT and AVP in...

  15. Selection of putative indicators of positive emotions triggered by object and social play in mini-pigs

    | Contributor(s):: Marcet Rius, Míriam, Cozzi, Alessandro, Bienboire-Frosini, Cécile, Teruel, Eva, Chabaud, Camille, Monneret, Philippe, Leclercq, Julien, Lafont-Lecuelle, Céline, Pageat, Patrick

    Positive welfare is more than the absence of negative experiences. Nevertheless, there are few feasible animal-based measures for positive welfare. This study aimed to investigate whether object and social play behaviours in pigs, which is believed to trigger positive emotions, is linked to...

  16. Working Smarter Not Harder: Oxytocin Increases Domestic Dogs' (Canis familiaris) Accuracy, but Not Attempts, on an Object Choice Task

    | Contributor(s):: Oliva, J. L., Mengoli, M., Mendonca, T., Cozzi, A., Pageat, P., Chabaud, C., Teruel, E., Lafont-Lecuelle, C., Bienboire-Frosini, C.

    Full-text: Available

    | Contributor(s):: Heintz, M. R., Fuller, G., Allard, S.

  18. Context and Individual Characteristics Modulate the Association between Oxytocin Receptor Gene Polymorphism and Social Behavior in Border Collies

    Full-text: Available

    | Contributor(s):: Borbála Turcsán, Friederike Range, Zsolt Rónai, Dóra Koller, Zsófia Virányi

    Recent studies suggest that the relationship between endogenous oxytocin and social affiliative behavior can be critically moderated by contextual and individual factors in humans. While oxytocin has been shown to influence human-directed affiliative behaviors in dogs, no study investigated yet...

  19. 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...

  20. Oxytocin Receptor Gene Polymorphisms Are Associated with Human Directed Social Behavior in Dogs (Canis familiaris)

    Full-text: Available

    | Contributor(s):: Anna Kis, Melinda Bence, Gabriella Lakatos, Enikõ Pergel, Borbála Turcsán, Jolanda Pluijmakers, Judit Vas, Zsuzsanna Elek, Ildikó Brúder, Levente Földi, Mária Sasvári-Székely, Adám Miklósi, Zsolt Rónai, Enikõ Kubinyi

    The oxytocin system has a crucial role in human sociality; several results prove that polymorphisms of the oxytocin receptor gene are related to complex social behaviors in humans. Dogs' parallel evolution with humans and their adaptation to the human environment has made them a useful...
