Your pet may be a genuine attachment figure — even if they’re ruining your sleep
I came across an article claiming that pets can become genuine attachment figures, rather than our bond with them simply being a form of affection or “over-attachment.”
I was curious, so I went looking at the original research. The evidence is more interesting — and more complicated — than the headline.
In attachment theory, an attachment figure can serve several functions. Two important ones are a “safe haven” — someone we turn to when distressed — and a “secure base” that gives us enough security to explore, pursue goals, etc.
A 2008 study by psychologist Lawrence Kurdek looked at four samples totaling 923 college students. Dogs showed particularly strong “proximity maintenance” and “secure base” characteristics.
Kurdek followed that with 975 adult dog owners in 2009. When distressed, participants reported being more likely to turn to their dogs than to mothers, fathers, siblings, best friends or children — although romantic partners still ranked above dogs.
Then researchers experimentally tested the idea.
In a 2012 study, 165 pet owners were assigned to conditions involving their pet being physically present, mentally activated, or absent while completing a goal-exploration task. Physical or cognitive pet presence was associated with generating more goals and greater confidence in achieving them.
In a second experiment with 120 pet owners, physical or cognitive pet presence during a distress-inducing task was associated with lower blood pressure.
The researchers interpreted these results as evidence that pets can, at least under some circumstances, perform “secure base” and “safe haven” functions.
But here's where I think it gets especially interesting.
A 2024 Scientific Reports study examined pet co-sleeping in 1,591 U.S. adults. Among people who co-slept with pets, about 60% said their pets had a positive or very positive effect on their sleep.
Yet statistically, pet co-sleeping was associated with poorer perceived sleep quality and greater insomnia severity.
So our subjective experience of what our pets are doing for us may not always match measurable outcomes.
Important caveat: the sleep study was cross-sectional and relied on self-report, so it cannot establish that pets caused poorer sleep. It also defined “co-sleeping” as sleeping in the same room, not necessarily the same bed.
Still, I love the contradiction: an animal may occupy a psychologically meaningful attachment role while also moving around, making noise, stealing half the bed and potentially disturbing your sleep.
For people who sleep with their pets: do you genuinely think you sleep better with them there, or do you know perfectly well they're disturbing your sleep and still wouldn't kick them out? 😄
