Sleep spindles are phasic bursts of thalamo-cortical activity, visible in the cortex as transient oscillations in the sigma range (usually defined in humans as 12–14 or 9–16 Hz). They have been associated with sleep-dependent memory consolidation and sleep stability in humans and rodents. Occurrence, frequency, amplitude and duration of sleep spindles co-vary with age, sex and psychiatric conditions. Spindle analogue activity in dogs has been qualitatively described, but never quantified and related to function. In the present study we used an adjusted version of a detection method previously validated in children to test whether detections in the dogs show equivalent functional correlates as described in the human literature. We found that the density of EEG transients in the 9–16 Hz range during non-REM sleep relates to memory and is characterized by sexual dimorphism similarly as in humans. The number of transients/minute was larger in the learning condition and for female dogs, and correlated with the increase of performance during recall. It can be concluded that in dogs, automatic detections in the 9–16 Hz range, in particular the slow variant (<13 Hz), are functional analogues of human spindles.

“…By contrast, pet dogs that had owners who tended to play more with them during the manipulation phase of a task committed more errors when retested in a memory task (Sümegi et al, 2014). These results might be used to suggest that the valence of the arousal rather than the level of arousal per se affects memory; however, Kis et al (2017) found no long-term effect of the play session on memory in a learning task despite finding decreased performance after a bout of play. This result suggests that the emotional arousal following play may not interfere with memory consolidation so much but instead might have more of an effect on other processes relevant to performance, such as attention.…”

Scent detection dogs are used in a variety of contexts; however, very few dogs successfully complete their training, and many others are withdrawn from service prematurely due to both detection accuracy issues in the field and wider behavioral issues. This article aims to review our understanding of the factors affecting variation in scent detection dogs' learning of the tasks and performance in the field. For this we deconstructed the scent detection task into its key behavioral elements and examined the literature relating to the factors affecting variation in the dogs' success all across their development. We first consider factors that affect individuality and individual performance, in general, such as temperament, arousal, the handler-dog relationship, training regimes, and the housing and management of scent detections dogs. We then focus on tasks specific to scent detection dogs and critically appraise relevant literature relating to the learning and performance of these tasks by dogs. This includes prenatal and early life exposure and later environment, training regime, and the human-dog relationship, as well as performance limiting factors such as the need to pant in hot environments during work.

“…The sleep macrostructure of dogs is composed of the stages of awakeness, drowsiness, non-REM and REM [24,39]. Beta activity (16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) is the dominant characteristic of dogs' awake state. The drowsiness stage is a transition between waking and sleep (characteristic of carnivore or insectivore species where the distinction between the awake and sleeping states is not clear [8]), and has been observed in dogs as well, with the highest power in the alpha band.…”

Sleep macrostructure is modulated by positive and negative social experience in adult pet dogs

The effects of emotionally valenced events on sleep physiology are well studied in humans and laboratory rodents. However, little is known about these effects in other species, despite the fact that several sleep characteristics differ across species and thus limit the generalizability of such findings. Here we studied the effect of positive and negative social experiences on sleep macrostructure in dogs, a species proven to be a good model of human social cognition. A non-invasive polysomnography method was used to collect data from pet dogs ( = 16) participating in 3-hour-long sleep occasions. Before sleep, dogs were exposed to emotionally positive or negative social interactions (PSI or NSI) in a within-subject design. PSI consisted of petting and ball play, while NSI was a mixture of separation, threatening approach and still face test. Sleep macrostructure was markedly different between pre-treatment conditions, with a shorter sleep latency after NSI and a redistribution of the time spent in the different sleep stages. Dogs' behaviour during pre-treatments was related to the macrostructural difference between the two occasions, and was further modulated by individual variability in personality. This result provides the first direct evidence that emotional stimuli affect subsequent sleep physiology in dogs.
