Abstract<\/strong><\/p>\n

The importance of dogs (Canis familiaris<\/em>) in sleep research is primarily based on their comparability with humans. In spite of numerous differences, dogs’ comparable sleep pattern, as well as several phenotypic similarities on both the behavioural and neural levels, make this species a most feasible model in many respects. Our aim was to investigate whether the so\u2010called first\u2010night effect, which in humans manifests as a marked macrostructure difference between the first and second sleep occasions, can be observed in family dogs. We used a non\u2010invasive polysomnographic method to monitor and compare the characteristics of dogs’ (N<\/em>\u00a0=\u00a024) 3\u2010hr\u2010long afternoon naps on three occasions at the same location. We analysed how sleep macrostructure variables differed between the first, second and third occasions, considering also the effects of potential confounding variables such as the dogs’ age and sleeping habits. Our findings indicate that first\u2010night effect is present in dogs’ sleep architecture, although its specifics somewhat deviate from the pattern observed in humans. Sleep macrostructure differences were mostly found between occasions 1 and 3; dogs slept more, had less wake after the first drowsiness episode, and reached drowsiness sleep earlier on occasion 3. Dogs, which had been reported to sleep rarely not at home, had an earlier non\u2010rapid eye movement sleep, a shorter rapid eye movement\u00a0sleep latency, and spent more time in rapid eye movement sleep\u00a0on occasion 3, compared with occasion 1. Extending prior dog sleep data, these results help increase the validity of further sleep electroencephalography investigations in dogs.<\/p>\n
