It's one of the first questions people ask, often in a whisper, half-ashamed: how long is this supposed to last? You want a number — a finish line to aim for. The honest answer is that grief doesn't run on a fixed clock. But research can offer something more useful than a deadline: a realistic picture of what to expect, so you can stop measuring yourself against a timeline that was never real.
What the Studies Show
Research on pet bereavement consistently finds that acute, intense grief is common in the first month or two, with many people reporting a gradual easing over the following several months. One often-cited body of work suggests that for a meaningful number of grievers, significant symptoms can persist for six months to a year — and that this is within the range of a normal response, not a disorder.
Crucially, studies also find that the intensity of pet grief is frequently comparable to grief over the loss of a human loved one. So if this feels as big as any loss you've faced, the data agrees with you.
Why "how long" is the wrong question
Grief researchers have largely moved away from rigid "stages" and tidy timelines. Modern models describe grief as something you learn to carry and integrate, not something you complete. The goal isn't to stop missing them. It's for the missing to take up a sustainable amount of space in your life again.
“You won't wake up one day ‘over it.’ Instead, the sharp ache slowly becomes a softer, more bearable presence. That's healing, doing exactly what it's supposed to do.”

What Affects the Timeline
Several things shape your individual experience with grief, and none of them are within your control to simply choose:
- The depth and length of the bond — a lifelong companion often leaves a longer, deeper ache than a shorter relationship.
- Whether the death was sudden or expected, which changes how much anticipatory grieving happened beforehand.
- The circumstances of the death — an accident or a hard euthanasia decision can complicate grief further.
- The support around you, including whether the people in your life take your loss seriously.
- What else is happening in your life at the same time, since grief rarely arrives in isolation.
Someone living alone whose pet was their primary companion may grieve longer and harder — and that's understandable, not pathological.
When to Seek Extra Support
Most pet grief, however intense, gradually softens on its own. But it's worth reaching out to a counselor or your doctor if, after several months, you find that grief is not easing at all, you're unable to function in daily life, you're withdrawing completely, or you're having thoughts of not wanting to be here. These can signal complicated grief or depression, which respond well to support.

The Real Answer
Grief lasts as long as it lasts — and then, more accurately, it changes form rather than ending. You won't wake up one day "over it." Instead, the sharp ache slowly becomes a softer, more bearable presence. That's not failure. That's healing, doing exactly what it's supposed to do.
