For most New Zealand kids, the family pet is there before they are. They learn to walk by holding onto the dog's back. They tell secrets to the cat. So when that pet dies, it is rarely "their first lesson about death" in a tidy sense. It is something messier and more important: their first big loss in a relationship that has no edges.
How adults handle the next few days shapes how children carry the loss for years. This guide is for parents and for vet teams who often end up coaching parents, in the carpark, on the day.
Start with the words you use
The single most important rule sits across every age group: say what happened in plain words.
"She died." "He has died." "We are going to help her die peacefully today."
It feels harsh in your mouth. It is far gentler than the alternatives.
Phrases to avoid, even when they're tempting:
- "We put him to sleep." Many children take this literally and become afraid of bedtime, or afraid that anaesthetic will kill them next time they go to the dentist.
- "She's gone away / on a long trip / gone to live on a farm." They will wait. They may also start to fear that you might leave on a trip too.
- "We had to." Children may worry the choice was forced — and then carry the imagined burden of a different choice.
The vet team can help by modelling the same language in front of the family.
What children actually understand, by age
These are guidelines, not rules. You know your child.
Under 4
Concept: very limited. They notice absence and disrupted routine.
What helps:
- Keep mealtimes, bedtimes and pickups predictable.
- Use the pet's name. "Pip is not here. Pip has died."
- Expect the question multiple times. Answer it the same way each time.
- Let them see you sad. Modelled sadness, in moderation, is permission to feel.
4 to 7
Concept: beginning to understand that death is permanent, but with magical-thinking gaps. They may believe they caused it.
What helps:
- Explicit reassurance: "It is not your fault. Animals get old or sick the same way trees do. We loved them and they loved us, and they died because their body stopped working."
- Concrete details. They will ask where the body is. Tell them, gently and truthfully.
- Drawing, story-making, "tell me a memory of [pet]" rituals.
8 to 12
Concept: largely adult-level understanding of death's permanence, but emotional regulation is still developing.
What helps:
- Honesty about choices. They can understand "the kindest thing was to help her die before she was in real pain."
- A role in the goodbye if they want one — choosing the blanket, picking the song, writing a letter to read aloud.
- Expect anger, withdrawal, perfectionism, or sudden silliness. These are all grief.
Teenagers
Concept: full. Emotional weight: often heavier than they let on.
What helps:
- Don't assume they're too cool for ritual.
- Don't insist they participate.
- Watch for academic dips, sleep changes, isolation. Refer to your GP if grief is interfering with daily life beyond a few weeks.
Should children be present for the euthanasia?
There is no single right answer.
Some Kiwi families want their children there. The child holds a paw, says goodbye, and feels included in something important. Many vet nurses tell us these are among the most peaceful goodbyes they have witnessed.
Other families want to spare the child the moment itself, and do the goodbye at home in the morning. That is also valid.
The wrong move is deciding for the child without consulting them. Where age allows, ask what they want. Tell them what will happen — the consult room will be calm, the vet will give two injections, their pet will fall asleep and then will die quietly. They can choose to be in the room, in the waiting area, or to say their goodbye at home and stay there.
Whatever they choose, never trick a child into the room. And never tell them their pet is "just sleeping" once it's done.
Involving children in the aftercare
Quiet, simple rituals help children carry grief well.
- Choose the blanket their pet will be wrapped in. (PetAftercare partner clinics use the family's own blanket where possible.)
- A paw print. Most clinics will offer one. Children often press their own hand alongside it later. The fur locket is another small, tangible thing they can keep.
- A name on a tree. Through Trees That Count, you can plant a native in their name. A pohutukawa, kowhai or kahikatea in your garden becomes their tree.
- A letter to read aloud. It does not have to be long.
- Matariki. When the new year stars rise, name the pet aloud with the people you have lost. Many NZ children tell us this is the ritual they keep across years.
What grief looks like in the weeks after
Children grieve in waves and in fragments. They may seem fine for two days and inconsolable on the third. They may grieve at bedtime, in the car, in the supermarket cereal aisle.
Common, normal:
- Asking the same questions repeatedly.
- Wanting to hold onto a piece of fur, a collar, a tag.
- Drawing the pet, writing about them, "talking" to them.
- A short period of clinginess, sleep regression in younger children.
- A wobbly first day back at school.
Worth a chat with your GP:
- Grief that is not gradually shifting after a couple of months.
- Sleep disruption that doesn't settle.
- Withdrawal from friends, school refusal, persistent anxiety.
- Self-blame that won't be reassured away.
What we send home with families
Through our partner clinics, every family with children receives our "Helping Children Cope" booklet at the appointment, alongside the standard sympathy card. It is short, gentle, age-banded, and meant to be read together. If your clinic isn't yet a partner and you'd like a copy, get in touch.
Children who are included, told the truth, and given small rituals tend to carry pet loss as a soft, real, formative grief — not as a confused, shaped-by-secrecy one. That is mostly within your reach as the adult on the day. We are here to help where we can.
PetAftercare partners with NZ vet clinics to provide complete end-of-life support for families, including grief booklets, keepsakes and the online memorial portal.
