“…In line with previous literature on humans and many other animal species [24,47,63,78,79], the results of this study indicated that mean HR (corrected for dynamic components of behavior) was linked to emotional arousal. Nevertheless, HR provides limited…”

“…However, some parameters can be ambivalent and difficult to interpret when considered separately. For example, HR can increase in both positive and negative emotional states, since it reflects arousal rather than valence [21,24,25]. The beat -tobeat variation (Heart Rate Variability -HRV), that reflects changes in the activity of the autonomic nervous system [26], is not differentially influenced by the valence of the test situations such as accessing to popcorn (positive situation) and crossing a black ramp (negative situation) in pigs [27].…”

Understanding how animals express positive emotions is becoming an interesting and promising area of research in the study of animal emotions and affective experiences.In the present study, we used infrared thermography in combination with behavioral measures, heart rate (HR) and heart rate variability (HRV), to investigate dogs' emotional responses to a potentially pleasant event: receiving palatable food from the owner. 2. Tail wagging could be a useful indicator of positive emotional state.3. Eye temperature can assess the arousal dimension of dogs' emotions in a positive situation.

“…Specifically, a sample of pet dogs participated in a separation test, which included relatively brief periods of contact with the owner, with a stranger, social isolation and reunion. The separation test was chosen as it has been established that it induces short-term distress in dogs [33], with reunion being a positive experience. From an applied perspective, assessing physiological correlates of separation distress in dogs is highly relevant, since it is a common condition compromising dog welfare [33][34][35][36][37].…”

“…Apart from an initial increase in heart rate during the first separation compared to resting heart rate at baseline, [33] and [44] found that social isolation was associated with a reduction in heart rate compared to when a person was present (but see [43]). This could be explained by dogs' higher activity during the person's presence; or the lowered heart rate during isolation might reflect episodes of parasympathetic rebound to sympathetic activation [44] or a depressive like response.…”

Highlights• Pet dogs were tested in a brief separation test and filmed remotely using thermography• Temperature was analyzed from selected patches of both ear pinnae simultaneously• Social isolation was associated with a significant decrease in ear pinnae temperature• Temperature of the two ears did not differ significantly from each other• Long distance thermography is a useful tool in non-invasive stress monitoring AbstractInfrared thermography can visualize changes in body surface temperature that result from stress-induced physiological changes and alterations of blood flow patterns. Here we explored its use for remote stress monitoring (i.e. removing need for human presence) in a sample of six pet dogs. Dogs were tested in a brief separation test involving contact with their owner, a stranger, and social isolation for two one-minute-periods. Tests were filmed using a thermographic camera set up in a corner of the room, around 7 metres from where the subjects spent most of the time. Temperature was measured from selected regions of both ear pinnae simultaneously. Temperature of both ear pinnae showed a pattern of decrease during separation and increase when a person (either the owner or a stranger) was present, with no lateralized temperature differences between the two ears. Long distance thermographic measurement is a promising technique for non-invasive remote stress assessment, although there are some limitations related to dogs' hair structure over the ears, making it unsuitable for some subjects.

Although owners can act as stress buffers for their dogs, whether dogs with poor early life histories with humans will respond similarly is unknown. We tested 45 dogs, 23 of which were rescued from adverse conditions, in a social paradigm in which a threatening stranger confronted them with either their owner or an unfamiliar human present. Salivary cortisol levels were assessed at three points, and the dogs' behavior and owners' responses to questionnaires were evaluated. Dogs from adverse backgrounds engaged in greater contact and exhibited more relaxed behaviors and social referencing when their owners were present. Dogs from the comparison group explored more when accompanied by their owners. Dogs from adverse backgrounds experienced greater decreases in cortisol levels from the first to third samples relative to dogs in the comparison group. Dogs from adverse backgrounds were also more likely to respond fearfully to a threatening stranger. Their owners rated them as having higher levels of strangerdirected fear, nonsocial fear, separation-related problems, attention seeking, and lower levels of chasing and trainability. These findings from this study suggest that early adverse environments may have lasting effects on dogs' social behavior.
