The science behind a grief nobody warned you about
Why Does Losing a Pet Feel Worse Than Losing a Person? If you’ve quietly wondered whether something is wrong with you for grieving your pet harder than you grieved a person, the research says no. A growing body of work on disenfranchised grief and prolonged grief disorder shows pet loss can hit as hard, or harder, than human loss — and there’s a reason almost nobody talks about it.
It isn’t that your pet mattered more than the people in your life. It’s that the grief itself works differently, and society never built the support structure to catch it.
The research is catching up to what pet owners already knew
A 2026 study out of Maynooth University, led by psychologist Philip Hyland, examined prolonged grief disorder — the diagnosis used when grief symptoms stay severe and disruptive for more than a year. Researchers found no measurable differences in how prolonged grief disorder symptoms show up, whether the loss involved a person or a pet. Pet loss accounted for 8.1% of all prolonged grief disorder cases studied — a higher share than several categories of human loss. MedicalXpressMedicalXpress
People who lost a pet were 27% more likely to develop prolonged grief disorder symptoms than people who hadn’t, a rate that landed between losing a parent and losing a sibling. Currently, only human deaths qualify for a prolonged grief disorder diagnosis at all — which means the clinical world may be undercounting a real and measurable form of suffering.

In a separate survey, one in five people who had experienced both kinds of loss said losing their pet was the harder one. Not equally hard. Harder. MedicalXpress
Why your pet’s death doesn’t come with a script
Human loss comes with infrastructure. Bereavement leave. Sympathy cards. People who know what to say, even if what they say is awkward. Pet loss comes with almost none of that, and researchers have a name for the gap: disenfranchised grief.
Researchers describe disenfranchised grief as what happens when a loss isn’t given the same validation or empathy by the people around you as a human loss would receive. That gap leaves people feeling isolated, and it often makes them less willing to even bring up how they’re feeling with the people closest to them. Cabi Digital LibraryCabi Digital Library
The term itself comes from grief researcher Kenneth Doka, who coined it to describe loss that can’t be openly mourned or publicly supported. Pet loss is one of the clearest examples. Take a week off for a parent’s death and no one questions it. Take a week off for a dog and you brace for the look.
There’s a second layer to this most people never hear named. Some bereaved pet owners experience what researchers call “double disenfranchisement” — their grief for the pet isn’t recognized in the first place, and on top of that, their emotional bond to an animal lower on the social hierarchy is treated as somehow abnormal. Lose a dog or cat and you’ll get more sympathy than someone grieving a rabbit or a fish — but still less than someone grieving a person. PubMed Central
The bond itself may be part of why it hurts more
It’s not only the missing support. Researchers point to something about the relationship itself. Pet relationships tend to be uncomplicated in a way human relationships rarely are — no old arguments, no things left unsaid, no complicated history to sort through after the fact. That simplicity is part of what makes the bond so strong, and part of what makes losing it land so hard. When the relationship was pure and uncomplicated, there’s nothing to soften the loss. No mixed feelings to lean on. Just absence.
A cross-cultural study comparing American and French Canadian pet owners found four themes running through their grief: a lack of validation and support, the sheer intensity of the loss itself, the particular nature of the human-pet bond, and the ongoing presence of a continuing bond with the pet after death. That last one matters — many people don’t simply grieve and move on. Research on continuing bonds shows responses to pet loss correlate closely with responses to human loss, which is part of why the loss carries the weight it does. PubMedPubMed Central
So what do you do with this?
Nothing about this research means you need to justify your grief to anyone, or rank it against other losses in your life. It means you can stop wondering if you’re overreacting. You’re not. You’re carrying a real loss, with real psychological weight, that the people around you were never taught how to recognize.
If you’re in the middle of it right now, one small thing that helps is having somewhere to put the memories instead of letting them sit scattered across your phone, half-organized, easy to avoid. The free 100 Photos. 1 Life. 7-Day Challenge was built for exactly this. It walks you through the photos you already have, one day at a time, and helps you capture the small stories behind them — about ten minutes a day, free, no pressure to finish if some days are harder than others.
When you’re ready — and there’s no schedule for that — Everhere takes those same photos, videos, and memories and turns them into a short, personalized tribute film built around who your pet actually was. Not a slideshow — a real questionnaire walks through their habits, their personality, the small things only you would know, and a film comes together from there, delivered within 48 hours. Every film comes with a QR placard you can place in a memorial space at home — a shelf, a windowsill, anywhere that’s theirs — so the film is always one scan away.
If you want to understand more about what goes into a tribute that actually feels like them, What Makes a Great Pet Memorial Video is a good next read. And if your grief feels disorienting in a way you weren’t prepared for, The Science Behind Why Losing a Pet Hurts This Much goes deeper into what’s happening in your brain right now.
You don’t need anyone’s permission to grieve this hard. The research already gave you one.
