The New York Times last week suggested that people who sleep with their dogs sleep just as well as those whose dogs sleep elsewhere:
The dogs wore a device called a Fitbark, an activity tracker that attaches to the collar and records whether an animal is at rest and sleeping or active and at play. The people wore an Actiwatch 2, an activity monitor that records people’s movements and whether they are sleeping soundly or not. Both monitors were set to sample movement every minute, while the humans also kept a sleep diary.
Over seven days of testing, the researchers found that with a dog in the bedroom, both the humans and the dogs slept reasonably well. Humans had a mean sleep efficiency, or the percentage of time spent asleep while in bed, of 81 percent, while dogs had a sleep efficiency of 85 percent. Levels over 80 percent are generally considered satisfactory. People slept slightly better when the dog was off the bed; dogs slept the same whether they were on the bed or in another location in the bedroom.
Dr. Carlo Siracusa, a veterinarian and the director of animal behavioral science at Penn Vet in Philadelphia, added that a dog sleeping in the same room or bed with humans won’t make Sparky think he’s top dog. “Dogs can distinguish between the relationship with its human fellows and other dogs, and the way in which they regulate their interactions with humans in the house is not trying to establish a hierarchy,” he said.
First, don't think for a moment that I haven't considered getting a Fitbark for Parker. I've always been curious what he does at day camp; I suspect he sleeps about 90% of the time.
Second, no matter how well Parker sleeps, there are sometimes days like last Thursday when he woke up with an urgent matter that he immediately discussed with the bedroom floor, even though I could have gotten him outside in seconds had he asked.
