观察了生活在不同城市栖息地的24只家犬的睡眠-觉醒周期和其他夜间行为。其中18只动物的记录是在红灯下用摄像机拍摄的。这些狗平均在8小时内有23次睡眠-觉醒。睡眠-觉醒周期由平均16分钟睡眠和5分钟清醒组成。所有的狗都在安静的睡眠中，大多数狗也在活跃的睡眠中。通常，活跃的睡眠之后会立即出现自发的觉醒。据报道，在人类和猫身上，一只狗在一个新的栖息地里被抑制了一晚的活跃睡眠，然后在接下来的两个晚上发生。在31种情况下，当两只或更多的狗睡在一起时，它们的睡眠-醒来周期不同步，只有在强烈刺激下才同步醒来。在18只被录像的狗中，有13只狗叫了，其中6只在8小时内叫了5次以上。14名狗主人中有9人无意中扰乱了狗的睡眠。狗的睡眠和醒来模式与已知的人类完全不同。这些不同的睡眠模式有时会导致狗对附近的人造成滋扰，但受到狗主人的欢迎，他们养狗既是为了保护自己，也是为了陪伴。
Sleep-wake cycles and other night-time behaviours were observed in 24 domestic dogs (Canis familiaris) living in various urban habitats. Recordings of 18 of these animals were made with a video camera under red light. On average, these dogs had 23 sleep-wake episodes during 8 h. The sleep-wake cycles consisted of an average of 16 min asleep and 5 min awake. All dogs were seen in quiet sleep and most dogs were also seen in active sleep. Usually active sleep was followed immediately by spontaneous arousal. As reported in humans and cats, active sleep was suppressed for a night in a dog placed in a new habitat, then it occurred the following 2 nights. On 31 occasions when two or more dogs were sleeping together, they had non-synchronous sleep-wake cycles, with waking only synchronising in response to a strong stimulus. Barking occurred in 13 of the 18 video-recorded dogs and six of these barked more than five times in 8 h. Nine of the 14 dog owners unwittingly disrupted the sleep of their dogs. The pattern of sleeping and waking in dogs was quite different from that known to occur in humans. These different sleep patterns sometimes led to dogs being a nuisance to people in the neighbourhood, but were welcomed by owners who kept their dog for protection as well as companionship.
