| Title | Do dogs follow behavioral cues from an unreliable human? | Type | Journal Article | ||

Abstract  |
Dogs are known to consistently follow human pointing gestures. In this study, we asked whether dogs “automatically” do this or whether they flexibly adjust their behavior depending upon the reliability of the pointer, demonstrated in an immediately preceding event. We tested pet dogs in a version of the object choice task in which a piece of food was hidden in one of the two containers. In Experiment 1, Phase 1, an experimenter pointed at the baited container; the second container was empty. In Phase 2, after showing the contents of both containers to the dogs, the experimenter pointed at the empty container. In Phase 3, the procedure was exactly as in Phase 1. We compared the dogs’ responses to the experimenter’s pointing gestures in Phases 1 and 3. Most dogs followed pointing in Phase 1, but many fewer did so in Phase 3. In Experiment 2, dogs followed a new experimenter’s pointing in Phase 3 following replication of procedures of Phases 1 and 2 in Experiment 1. This ruled out the possibility that dogs simply lost motivation to participate in the task in later phases. These results suggest that not only dogs are highly skilled at understanding human pointing gestures, but also they make inferences about the reliability of a human who presents cues and consequently modify their behavior flexibly depending on the inference. | ||||

| Title | Cortisol levels in hair reflect behavioural reactivity of dogs to acoustic stimuli | Type | Journal Article | ||
| Year | 2013 | Publication | Research in Veterinary Science | Abbreviated Journal | |
| Volume | 94 | Issue | 1 | Pages | 49-54 |
| Keywords | Dogs; Behaviour; Cortisol; Hair; Acoustic stimuli | ||||
| Abstract |
Cortisol levels in hair samples were examined in fourteen domestic dogs and related to the dogs’ responses to different acoustic stimuli. Stimuli were playbacks of species-typical vocalizations recorded during three different situations (“disturbance”, “isolation” and “play” barks) and the sounds of a thunderstorm. Hair samples were collected at 9:00 h and 17:00 h two weeks after the behavioural tests. Results showed that behavioural reactivity to playback of the various stimuli correlates with cortisol levels in hair samples collected at 9:00 h, and the same was the case for the separate measures of behaviour (i.e. hiding, running away, seeking attention from the tester, panting and lowering of the body posture). Hence, levels of cortisol in hair appear to reflect the dog’s chronic state of emotional reactivity, or temperament. | ||||

| Title | Utility of livestock-protection dogs for deterring wildlife from cattle farms | Type | Journal Article | ||
| Year | 2010 | Publication | Wildl. Res. | Abbreviated Journal | Wildl. Res. |
| Volume | 37 | Issue | 8 | Pages | 715-721 |
| Keywords | bovine tuberculosis, coyote, grey wolf, livestock protection dog, mesopredators, white-tailed deer, wildlife damage management. | ||||
| Abstract |
Context. Livestock producers worldwide are negatively affected by livestock losses because of predators and wildlife-transmitted diseases. In the western Great Lakes Region of the United States, this conflict has increased as grey wolf (Canis lupus) populations have recovered and white-tailed deer (Odocoileus virginianus) have served as a wildlife reservoir for bovine tuberculosis (Myobacterium bovis).Aims. We conducted field experiments on cattle farms to evaluate the effectiveness of livestock-protection dogs (LPDs) for excluding wolves, coyotes (C. latrans), white-tailed deer and mesopredators from livestock pastures.Methods. We integrated LPDs on six cattle farms (treatment) and monitored wildlife use with tracking swaths on these farms, concurrent with three control cattle farms during 2005-2008. The amount of time deer spent in livestock pastures was recorded using direct observation.Key results. Livestock pastures protected by LPDs had reduced use by these wildlife compared with control pastures not protected by LPDs. White-tailed deer spent less time in livestock pastures protected by LPDs compared with control pastures not protected by LPDs.Conclusions. Our research supports the theory that LPDs can be an effective management tool for reducing predation and disease transmission. We also demonstrate that LPDs are not limited to being used only with sheep and goats; they can also be used to protect cattle.Implications. On the basis of our findings, we support the use of LPDs as a proactive management tool that producers can implement to minimise the threat of livestock depredations and transmission of disease from wildlife to livestock. LPDs should be investigated further as a more general conservation tool for protecting valuable wildlife, such as ground-nesting birds, that use livestock pastures and are affected by predators that use these pastures. | ||||

| Title | Effect of affiliative and agonistic relationships on leadership behaviour in free-ranging dogs | Type | Journal Article | ||
| Year | 2010 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
| Volume | 79 | Issue | 5 | Pages | 981-991 |
| Keywords | affiliative relationship; agonistic dominance; Canis lupus familiaris; consensus costs; consensus decisions; domestic dog; formal dominance; individual variation in leadership | ||||
| Abstract |
Consensus decisions about the nature and timing of group activities allow animals to maintain group cohesiveness, but also entail costs because individuals often differ with respect to their optimal activity budgets. Two mechanisms whereby animals reach a consensus include ‘consistent leadership’, in which a single dominant individual makes the decision, and ‘variable leadership’ in which several group members contribute to the decision outcome. Sharing of consensus decisions is expected to reduce consensus costs to most group members. Both patterns are thought to emerge from the complexity of social relationships of group members. We investigated the distribution of leadership during group departures in two packs of free-ranging dogs, Canis lupus familiaris, and tested how its distribution between individuals was affected by dominance rank-related affiliative and agonistic relationships. Although leadership was not entirely concentrated on a single group member, both packs had a limited number of habitual leaders. In the largest pack, the pattern of leadership changed from ‘variable’ to nearly ‘consistent’ after its size had shrunk. Habitual leaders were usually old and high-ranking individuals. However, high-ranking dogs that received affiliative submissions in greeting ceremonies were more likely to lead than dominant dogs receiving submissions only in agonistic contexts. During resting times, habitual followers associated more closely with habitual leaders than with other followers. These results suggest that in social species collective movements may arise from the effort of subordinates to maintain close proximity with specific valuable social partners. | ||||

| Title | Dogs’ attention towards humans depends on their relationship, not only on social familiarity | Type | Journal Article | ||
| Year | 2013 | Publication | Abbreviated Journal | Animal Cognition | |
| Volume | 16 | Issue | 3 | Pages | 435-443 |
| Keywords | Domestic dogs; Social attention; Social familiarity; Dog–human relationship | ||||
| Abstract |
Both in humans and non-human animals, it has been shown that individuals attend more to those they have previously interacted with and/or they are more closely associated with than to unfamiliar individuals. Whether this preference is mediated by mere social familiarity based on exposure or by the specific relationship between the two individuals, however, remains unclear. The domestic dog is an interesting subject in this line of research as it lives in the human environment and regularly interacts with numerous humans, yet it often has a particularly close relationship with its owner. Therefore, we investigated how long dogs (Canis familiaris) would attend to the actions of two familiar humans and one unfamiliar experimenter, while varying whether dogs had a close relationship with only one or both familiar humans. Our data provide evidence that social familiarity by itself cannot account for dogs’ increased attention towards their owners since they only attended more to those familiar humans with whom they also had a close relationship. | ||||

| Abstract |
Based on an intensive analysis of literature, the study summarizes problems involved in the significance of domesticated dogs as objects of instruction and assistants of the education of children. Several important topics are discussed in view of advances for children in families keeping dogs. Such topics are mainly related to a general socio-emotional level, the support of cognitive development and character formation. Further aspects are the acquisition of a sense of responsibility, and the development of self-confidence, a sense of social membership and security, as well as important attributes of character such as frankness, broad mindedness, and sympathetic understanding. Moreover, knowledge about the life cycle and functions of body organs can be conveyed, and the dog could, at least in part, substitute for brothers and sisters. Basically, positive attitudes towards animals in general, as well as nature and environment are supported. All topics are critically commented and considered to be realistic or not. The supporting role of parents, in particular, is emphasized. Parental commitment should include deep concern with the typical attributes of the dog breed desired, and optimal dog keeping conditions to prevent harm to the children. The final commentary lays special emphasis on negative features of domestication for a pet owner, and cautions against non-biological and illusionary ideas about domesticated animals. | ||||

| Abstract |
Autoren B. Agnetta, B. Hare, M. Tomasello Zusammenfassung The results of three experiments are reported. In the main study, a human experimenter presented domestic dogs (Canis familiaris) with a variety of social cues intended to indicate the location of hidden food. The novel findings of this study were: (1) dogs were able to use successfully several totally novel cues in which they watched a human place a marker in front of the target location; (2) dogs were unable to use the marker by itself with no behavioral cues (suggesting that some form of human behavior directed to the target location was a necessary part of the cue); and (3) there were no significant developments in dogs' skills in these tasks across the age range 4 months to 4 years (arguing against the necessity of extensive learning experiences with humans). In a follow-up study, dogs did not follow human gaze into “empty space” outside of the simulated foraging context. Finally, in a small pilot study, two arctic wolves (Canis lupus) were unable to use human cues to locate hidden food. These results suggest the possibility that domestic dogs have evolved an adaptive specialization for using human-produced directional cues in a goal-directed (especially foraging) context. Exactly how they understand these cues is still an open question. Schlüsselwörter Key words Dogs – Arctic wolves – Social cognition – Gaze following – Communication |

| Abstract |
Animals with relatively highly developed brains are likely to experience some degree of self-awareness and the ability to think. As well as being interesting in its own right, self-consciousness matters from an ethical point of view, since it can give rise to forms of suffering above and beyond the immediate physical sensations of pain or distress. This article surveys the evidence for animal self-consciousness and its implications for animal welfare. | ||||

| Title | Dogs steal in the dark | Type | Journal Article | ||
| Year | 2013 | Publication | Abbreviated Journal | Animal Cognition | |
| Volume | 16 | Issue | 3 | Pages | 385-394 |
| Keywords | Domestic dog; Social cognition; Perspective taking; Competition | ||||
| Abstract |
All current evidence of visual perspective taking in dogs can possibly be explained by dogs reacting to certain stimuli rather than understanding what others see. In the current study, we set up a situation in which contextual information and social cues are in conflict. A human always forbade the dog from taking a piece of food. The part of the room being illuminated was then varied, for example, either the area where the human was seated or the area where the food was located was lit. Results show that dogs steal significantly more food when it is dark compared to when it is light. While stealing forbidden food the dog’s behaviour also depends on the type of illumination in the room. Illumination around the food, but not the human, affected the dogs’ behaviour. This indicates that dogs do not take the sight of the human as a signal to avoid the food. It also cannot be explained by a low-level associative rule of avoiding illuminated food which dogs actually approach faster when they are in private. The current finding therefore raises the possibility that dogs take into account the human’s visual access to the food while making their decision to steal it. | ||||

| Abstract |
Aging pets often suffer a decline in cognitive function (eg, memory,learning, perception, awareness) likely associated with age-dependent brain alterations. Clinically, cognitive dysfunction may result in various behavioral signs, including disorientation; forgetting of previously learned behaviors, such as house training; alterations in the manner in which the pet interacts with people or other pets;onset of new fears and anxiety; decreased recognition of people, places, or pets; and other signs of deteriorating memory and learning ability. Many medical problems, including other forms of brain pathologic conditions, can contribute to these signs. The practitioner must first determine the cause of the behavioral signs and then determine an appropriate course of treatment, bearing in mind the constraints of the aging process. A diagnosis of cognitive dysfunction syndrome is made once other medical and behavioral causes are ruled out. | ||||
