A new survey conducted at Canisius College in Buffalo, New York, discovered that adult women sleep better with a dog in their bed.

Of the 962 women living in the U.S. interviewed by the school, 55 percent of them shared the bed with at least one dog and 31 percent of them shared the bed with at least one cat. The study found 57 percent of the women shared the bed with a human partner. Dogs were less likely to wake their owners in the middle of the night than cats and humans, results revealed.

The study found that both cats and humans were equally disruptive to women’s sleep and provided them with fewer feelings of comfort and security than dogs.

Dog owners also reported earlier sleep and wake times than cat owners and participants without pets. “Dog ownership and its associated responsibilities may cause individuals to adhere to a stricter routine,” researchers said. “Keeping to a consistent sleep schedule may be beneficial to dog owners.”
