For many children, this may be their first close experience of death. Clear, age appropriate explanations can reduce confusion while the family is grieving too.
Why the euphemisms cause trouble
Put to sleep is the phrase almost everyone reaches for, and it is the one that causes the most predictable problems. Children who are told the dog was put to sleep sometimes become afraid of going to bed, or frightened when a family member has an operation.

Gone away and we lost her invite a different problem: a child who waits for the dog to come back, or who believes she could be found if someone looked properly. Plain language is kinder than it sounds, and it prevents a second confusion arriving on top of the grief.
What to say, roughly by age
| Age | What tends to help |
|---|---|
| Under about 5 | Very concrete. Her body stopped working and she died. She will not come back. Expect the same question repeatedly; answer it the same way each time. |
| About 5 to 9 | Honest about cause and about the decision if there was one. This age often asks whether they caused it, and needs telling clearly that they did not. |
| About 10 and older | Include them in what is happening. Give them a real choice about being present, and accept whichever they choose without persuading. |

Should they be there
There is no single right answer, and a child who does not want to be present should not be talked into it. A child who does want to be present should be told beforehand what will happen, in plain terms, including that the dog's eyes may stay open and that there may be a twitch or a last breath afterwards.
Have one adult whose only job is the child, so someone can leave the room with them at any point without the appointment stopping.
Afterwards
Tell the school. A child who is quiet or unusually short tempered in the following days or weeks is easier for a teacher to support if they know why.
Let them do something concrete. Choosing where ashes go, drawing her, keeping the collar, planting something. Children process through doing more reliably than through talking, and being given a job is often a relief.
Expect it to resurface. Birthdays, the anniversary, a new dog in the street, a school project about families. Grief in children tends to arrive in short bursts separated by apparently normal weeks, which is not the same as being over it.
Where to read more
The Ohio State University Veterinary Medical Center publishes a printable guide written specifically for families facing the serious illness or death of a companion animal. It is worth reading before the appointment rather than after, and it is free.
