Most people feel the worst of it in the first one to two months. After that, a quieter ache tends to settle in and can last up to a year, sometimes longer, before it loosens its grip. There is no single correct timeline, and that is not a dodge. It is what the research actually shows, and it is a kinder answer than the tidy stage charts most grief articles reach for.
If you are reading this a week after your pet died and you feel like you are underwater, that is not a sign you are handling it badly. If it has been eight months and you still tear up at their empty water bowl, that is not a sign you are stuck. Both are inside the ordinary range of how this works.
How long does pet grief usually last?
Grief after losing a pet tends to move in two phases. The first is acute: the days and weeks right after the loss, when sadness can feel physical, sleep gets strange, and small reminders (their leash by the door, the quiet house) land hard. For most people, that sharp edge is heaviest in the first one to two months.
After that, the pain usually does not vanish so much as it loosens. A dull sadness, grief researchers sometimes describe it as an underlying ache rather than acute pain, can continue for up to a year for a lot of people. It often comes back in waves around a birthday, an anniversary of the loss, or just a season that reminds you of walks you used to take together. None of that means you have slid backward. Grief for a pet rarely ends on a date. It fades unevenly, with good stretches and sudden hard days mixed in.
Can losing a pet really hurt as much as losing a person?
For a lot of people, yes, and there is now research that backs that up instead of just saying it to be comforting. A study published in January 2026, surveying 975 adults in the United Kingdom, asked people who had lost both a pet and a person which loss had hit them harder. One in five chose the pet.
The same study measured how many pet owners met the clinical criteria for prolonged grief disorder, which is the term researchers use when grief stays just as intense for much longer than is typical and starts interfering with daily life. About 7.5% of the pet-bereaved people in the study met that bar. For comparison, the rate after losing a close friend was 7.8%, and after losing a sibling it was 8.9%. Pet loss did not behave like a lesser grief in this research. It behaved like grief, full stop.
If people in your life have brushed off how hard this has hit you, that reaction says something about them, not about the size of what you lost. Our piece on why losing a pet hurts so much goes deeper into the reasons the bond runs this deep.
What does it mean if grief does not ease after six months or a year?
For most people, the sharpest pain softens with time even if it never fully disappears. But the same 2026 study found that for a smaller share of pet owners, roughly 7.5%, grief does not loosen. It stays heavy, intrusive, and hard to set down, month after month, in a way that starts crowding out work, sleep, or the people around them.
That is not a personal failing and it is not rare enough to be shameful. It is a recognized pattern with a name, and it responds to help. If that description sounds like where you are, especially if it has been many months and the weight has not shifted at all, it is worth talking to a grief counselor, a doctor, or a pet loss support line rather than waiting to see if it passes on its own. Cornell University's Pet Loss Support Hotline is staffed by trained veterinary students and can be reached at 607-218-7457, though hours shift with the school calendar, so it is worth calling to check current times.
Do you have to move through the five stages in order?
You may have seen grief described as five neat stages: denial, anger, bargaining, depression, acceptance. That framework was never built to be a checklist, and it was not built with pet loss in mind at all. In practice, most people do not move through it in a straight line. You might feel denial and anger on the same afternoon, skip bargaining entirely, or feel a wave of acceptance in week two and a wave of anger in month four.
If your grief does not look like a tidy progression, that is not you doing it wrong. Almost nobody's does. If you want a closer look at the stages themselves and whether they really fit a pet's loss, our dedicated guide to pet loss grief stages goes further into each one.
What helps while you are waiting for it to soften?
There is no shortcut, because the ache is the shape that love takes once the one you loved is gone. But a few things tend to help people move through it rather than around it.
Let the early weeks be as hard as they are instead of rushing to feel better. Keeping gentle routines, a daily walk, a set time to eat, a quiet moment at the same hour your pet used to settle beside you, gives shape to days that otherwise feel unmoored. Talking to people who understand, whether that is one patient friend, a support group, or a hotline, matters more than most people expect, especially since not everyone around you will understand why this hurts the way it does.
Many people also find it comforting to keep something close that holds their pet's shape: a favorite photo somewhere you see it daily, a paw impression you made while they were here, or a small keepsake you can hold on the hard nights. If a photo is what you have left, some people turn it into a sculpted figurine shaped like their pet, something physical to keep nearby when the ache comes back in waves. There is no rush to decide any of that, and no right way to grieve a companion who mattered this much. You are allowed to take as long as it takes, even if that is a year, or longer than anyone around you expected.
If grief found you before the goodbye too, you may also recognize some of it in anticipatory grief, the mourning that can start while your pet is still here. If your pet's death came suddenly instead, without that slow preparation, that is its own kind of hard, and coping with a sudden pet loss speaks to that shock directly. If guilt keeps circling back, about a decision you made or one you wish you had made sooner, our piece on pet loss guilt may help with that too.
