The Healing Power of Pets: What Our Animals Give Us — and What the Science Says
By Dr Danielle Baillieu
Perhaps it was the dog who nudges you outdoors on a grey morning, or the cat who settles beside you when the day has been long. There is often one animal whose presence simply makes home feel more like home.
If you have a pet, take a moment to think about what that relationship gives you. And if you don’t, you may still know the particular comfort of being with an animal you love.
For many people, that bond is profound. But what does the research say about pets and mental health?
What the research actually shows
The honest answer is encouraging, but not simplistic. A 2025 review by McConnell, Folmsbee and Aldstadt describes ways companion animals may support wellbeing directly: through companionship, social support and stress regulation, and indirectly, by helping people connect with others. The authors also acknowledge mixed findings and important limits: pets are not a panacea, and their effects differ between people and circumstances.
A 2026 qualitative review brought together 24 studies of people living with mental health difficulties. Participants described pets as sources of emotional co-regulation, trust, routine, responsibility and meaning. These accounts help explain how a particular relationship can feel supportive in everyday life. They do not, however, prove that pet ownership is a treatment or that everyone will experience the same benefits.
Population-level findings are more mixed still. A 2025 meta-analysis of observational studies found no significant overall association between pet ownership and depression risk. Its findings cannot establish cause and effect, and a modest association for cat ownership changed in sensitivity analysis. The useful takeaway is not that one kind of pet helps or harms everyone. It is that ownership alone tells us little about the quality of a relationship or the circumstances around it.
In a 2026 study, researchers also explored social and biological pathways. Dog ownership was associated with some closer social connections, but the researchers found no significant direct effect of dog or cat ownership on wellbeing. That distinction matters: the benefits may sometimes come through the everyday experiences an animal helps make possible, rather than from simply having a pet.
The body in the bond
There is a biological side to this connection. Oxytocin, a hormone involved in social bonding, has been studied in human–dog interaction. In a 2015 study, mutual gaze between dogs and their owners was linked with changes in oxytocin, suggesting a possible feedback loop. This is a finding about particular interactions, not proof that every cuddle produces the same response, or that oxytocin explains every meaningful bond.
Gentle touch can also focus attention on something concrete: warm fur, a steady breath, the small movement of a hand. For some people, this quiet sensory experience feels settling. Research on human–animal interaction has examined stress-related physiology, including cortisol and the hypothalamic–pituitary–adrenal (HPA) axis, which helps regulate the body’s stress response. Results vary, though; it would be too strong to promise that stroking a dog reliably lowers cortisol for everyone. A 2026 study, for instance, found cortisol was associated with conversation with close others, rather than pet ownership itself.
So, if your body softens when your pet leans against you, that experience is real. The precise biology behind it is still being studied.
Routine, structure and a reason to begin
Pets can also provide external scaffolding: regular care tasks that give shape to a day. Feeding times, walks, fresh water and play can create gentle prompts when self-directed routine feels hard to organise.
That can be especially relevant if executive-function difficulties make it challenging to start or sequence everyday tasks. For some neurodivergent people, an animal’s needs offer a meaningful cue when “I should do this for myself” is difficult to translate into action. This is not a cure for ADHD or autism, and it should never mean that a person has to manage pet care without support. The routine needs to work for both the person and the animal.
One small reflection tool I use is Name–Normalise–Redirect, Dr Danielle’s own framework for reflection and communication. It is not a validated treatment protocol; it is a way to move from self-criticism towards a kinder next step:
Name → Normalise → Redirect
Name: “I keep telling myself I’ll go for a walk, but I can’t get started.”
Normalise: “Needing external structure isn’t a weakness; my dog’s dinner time is doing some of the heavy lifting for me.”
Redirect: “The walk happens when the dog needs it. I can borrow that momentum rather than fight for motivation.”
A 2026 study of adult cat owners, including people with autism and ADHD, offers an important reminder that this is not a fairy tale. Most everyday cat–human factors were not significantly associated with distress, but some difficulties (including anxious cat behaviour, poor cat health or feeling unable to provide care) were associated with worse wellbeing. The study was cross-sectional, so it cannot tell us what caused what. Still, the bond goes both ways: our animals’ needs and health matter, and caring for them can sometimes be stressful.
What pets teach us about health, illness and loss
Caring for an animal brings us face to face with the circle of life in a way that is hard to avoid. Pets get ill, they age, and often they die before us. That reality is difficult, and it is also quietly instructive.
Looking after a pet through illness teaches vigilance and tenderness: noticing a change in appetite or energy, taking it seriously, and doing what you can even when you cannot fix everything. It is practice in paying attention, and in accepting limits — two things that serve us well when we face our own health or the health of people we love. Grieving a pet, when it comes, is a genuine grief. A recent narrative review describes pet loss grief as real, significant and frequently comparable to the loss of a human family member, while noting that it is often dismissed or minimised as “disenfranchised” grief (Ngo, Oh, Kim & Lee, 2026). How we support that grief matters. Many people also say that experiencing loss through a pet, in a relationship uncomplicated by words, prepared them in some small way for other losses later in life. Death is part of the circle, and an animal's life — shorter than ours — teaches it honestly.
Pets and our relationships with people
An animal can be a companion in their own right, and sometimes a bridge to other people. A dog walk may open the door to a neighbourly hello; a shared affection for animals can give a conversation somewhere easy to begin. The 2026 social-pathways study suggests that wider human connection may be one route through which pets are associated with wellbeing.
Nevertheless, animals are complements to human connection, not substitutes for it. A pet cannot provide every kind of practical, relational or professional support you may need. If distress is persistent, severe or affecting daily life, it is reasonable to seek help as well as drawing comfort from your animal. You can find out more about psychological support and services.
Compassionate Final Note
The bond you share with an animal may be woven into the small things: the greeting at the door, the daily ritual, the quiet company when words feel like too much. Research is learning to describe some of these pathways, while also reminding us that no single answer applies to everyone.
Your connection does not need to be measured against anybody else’s. The bond is real; the evidence suggests it can matter; and care flows both ways. We look after them, and in their own animal ways, they can help look after us.
