Introduction
Your pet is dying, or has just died, and you’re facing one of the hardest conversations you’ll ever have with your child. You want to protect them from pain. You’re searching for the “right” words that will somehow make this easier. You wonder if they’re too young to understand, or if honesty will traumatize them.
Here’s what we want you to know from the start: there’s no perfect way to do this. But research consistently shows that honest, age-appropriate conversations about death—even when they’re difficult—help children develop healthy ways of understanding and processing loss throughout their lives.
We’re not child psychologists or grief counselors. We’re veterinarian professionals who help families through pet euthanasia every day, and we’re often asked how to talk to children about what’s happening. This article draws on research from child development experts and bereavement counselors to offer guidance on having these conversations with compassion and honesty, organized by your child’s age and developmental stage. Ultimately, you know your child and your family best—these are suggestions to help guide your decisions, not rigid rules.
Why Honest Language Matters (At Every Age)
Before we talk about specific ages, one principle applies universally: the words you use matter profoundly.
Research from UC Davis School of Veterinary Medicine, Stanford Children’s Health, and the American Academy of Pediatrics consistently shows that using direct words like “death,” “dying,” and “died” helps children understand what has actually happened, even when those words feel harsh to say out loud.
The alternative—euphemisms—creates confusion and can actually cause harm in ways you might not expect. When you tell a young child that their pet was “put to sleep,” they may become terrified of bedtime, worried they won’t wake up. When you say the pet “ran away,” children wonder why their beloved companion left them, or they hold onto hope that the pet will return. And while religious explanations can be comforting and appropriate for many families, phrases like “went to heaven” need context—otherwise, young children might expect the pet to come back from heaven, since they don’t yet understand that heaven means the pet won’t return to their physical life.
According to bereavement counselors who work with grieving families, honesty delivered with compassion is always better than well-meaning fiction. The trust you build by being truthful now will serve your relationship with your child for years to come.
Infants and Toddlers (0-2 Years)
Babies have no concept of death, according to Stanford Children’s Health. But as the Canadian Virtual Hospice points out in their research on childhood grief, infants and toddlers react intensely to changes in routine and to the emotions of the adults around them. They sense that something is wrong even if they can’t understand what or why.
What to Say
You don’t need a complex explanation for very young children. A simple acknowledgment is enough: “[Pet’s name] died. They’re not here anymore. I know you miss them.” Your tone and your consistent presence matter far more than the specific words you choose.
Including Them in the Process
Very young children generally shouldn’t be present for euthanasia, as they won’t understand what’s happening and may become distressed by adult emotions without the cognitive ability to process why everyone is sad. If you’re choosing in-home euthanasia, have your toddler say goodbye to the pet earlier in the day, then arrange for them to be with another trusted caregiver during the actual procedure.
What Grief Looks Like
You might see fussiness, clinginess, irritability, changes in sleep or eating patterns, or regression in behaviors like toileting. Your child isn’t grieving the pet in the way an older child would—they’re responding to the disruption in their world and to your emotional state.
What Helps Most
Maintain routines as strictly as possible. Provide extra physical comfort through holding, cuddling, and consistent presence. Keep their environment as stable as you can manage during this difficult time.
Preschool Age (3-5 Years)
Children in this age group typically view death as temporary and reversible—much like cartoon characters who “die” and pop back up in the next scene. According to the Palliative Care Network of Wisconsin, preschoolers often engage in what’s called “magical thinking,” believing their own thoughts or actions might have caused the death.
This is why you might hear the same questions over and over: “Where is Fluffy?” “When is she coming back?” They’re not asking because they didn’t hear your answer. They’re asking because they’re trying to process a concept that simply doesn’t fit their understanding of how the world works.
What to Say
Use simple, concrete language: “When a pet dies, their body stops working. They don’t breathe anymore. They don’t eat or sleep or feel anything. They won’t come back, and we’ll miss them very much.”
Expect to repeat this explanation many times. Each repetition helps them process this new concept a little bit more.
If your child expresses guilt—”Did Fluffy die because I was bad?”—reassure them clearly and directly: “No, nothing you did or thought made [pet] die. [Pet] died because [they were very old / very sick / their body stopped working]. You didn’t cause this at all.”
Should They Be Present for Euthanasia?
This decision is highly individual and depends on your specific child’s maturity and temperament. According to veterinarians who regularly work with families during euthanasia, some children in this age group can benefit from being present with proper preparation, while others may find it confusing or frightening.
The key factors to consider: Can you prepare them adequately for what will happen? Are you emotionally composed enough to support them through it? Is your child generally calm in new situations, or do they become easily overwhelmed by change?
If you’re unsure, you can offer the choice in simple terms and respect whatever they decide. Many families with children this age choose to have them say goodbye before the procedure rather than being present during.
How to Involve Them
If saying goodbye before (most common for this age):
Let them pet and talk to their pet one last time. Have them draw a picture or make a card for the pet. Let them choose one of the pet’s favorite toys to keep. During the actual procedure, give them a job to do with another adult—maybe making cookies in the kitchen or doing a craft project. Having a specific role helps them feel less excluded while keeping them at a comfortable distance.
If they choose to be present (with careful preparation):
Explain the process in very simple terms: “The doctor will give [pet] special medicine. [pet] will close their eyes and go to sleep, and their heart will stop. They won’t feel anything at all.”
Warn them about things that might surprise them: “[Pet]’s eyes might stay open. They might take a big breath. These things are normal and don’t mean they’re in pain.”
Give them a simple, concrete role. They might hold a favorite toy near the pet, or—and this is one of the most valuable jobs you can give them—they can be the “tissue helper” who hands tissues to crying family members. This role accomplishes two important things: it gives them a sense of purpose and agency, and it shows them that it’s completely normal and okay for adults to be sad and to cry.
After the procedure:
If they want to see the pet’s body, allow it with a simple explanation: “See, [pet] isn’t moving or breathing anymore. Their body stopped working.” Some children want this closure; others don’t. Both responses are completely normal.
What Grief Looks Like
Watch for regression behaviors like thumb-sucking or bedwetting, increased clinginess, sleep disruptions, repetitive questions, or denial. You might also notice them playing out death themes in their games—having toy animals “die” and “come back to life.” This is actually normal processing, not something to be concerned about.
What Helps Most
Children’s books about pet loss can be incredibly helpful at this age (see our resource list at the end). Maintain regular routines as much as possible. Create simple memorials together—plant a flower in the pet’s memory, draw pictures, look at photos. And perhaps most importantly, give them permission to be sad AND to play normally. Grief in young children often looks like shifting between sadness and regular play, and both are healthy.
Early Elementary (6-8 Years)
According to Stanford Children’s Health, children in early elementary school are beginning to understand that death is final, but they often don’t yet grasp that it’s universal—that it will eventually happen to everyone, including them and the people they love. They may personify death as a skeleton, an angel, or a ghost, and they typically become intensely curious about the physical process of what happens when someone dies.
Don’t be surprised if they express anger at the deceased pet, at you, or at the veterinarian for “not saving” the pet. This is normal processing of difficult emotions, not misbehavior that needs correction.
What to Say
You can be more detailed with children this age: “The veterinarian said [pet] has a disease that makes them hurt all the time, and there’s no medicine that can fix it. Their body is wearing out. We’ve decided to have the veterinarian help [pet] die peacefully so they don’t have to be in pain anymore.”
Answer their questions honestly, including questions about the body and what happens physically. They’re trying to understand a complex concept, and factual information actually helps more than you might think.
Should They Be Present for Euthanasia?
This age group often benefits from being present if they choose it and are properly prepared. According to UC Davis bereavement counselors who work extensively with families, children in this developmental stage who choose to attend euthanasia often report that it provided closure and helped demystify death in a way that reduced anxiety rather than increasing it.
The absolutely crucial word here is choose. Offer the option clearly, explain what will happen, and make it crystal clear that either choice is perfectly okay—there’s no right or wrong answer.
How to Frame the Choice
“The veterinarian is going to give [pet] medicine that will help them die peacefully without any pain. You can be there to pet them and say goodbye if you want to. Or you can say goodbye before, and not be in the room when it happens. There’s no right or wrong choice—it’s whatever feels right to you.”
How to Involve Them (If They Choose to Be Present)
Prepare them beforehand:
Explain the process: “The doctor will give an injection. [Pet] will relax and fall asleep, and then their heart will stop beating. It happens quickly and doesn’t hurt.”
Warn them about things that might be surprising: “[Pet]’s eyes might stay open after they die. They might take one big breath. Their body might twitch or relax in ways that look strange. These are all normal things that happen when a body stops working, and they don’t mean the pet is in pain.”
During the procedure:
Let them pet or hold the pet if they want to. Give them meaningful roles: they might hold a favorite toy near the pet, be the one to give the pet a treat beforehand, or choose the music that plays in the background. And again, that tissue distribution role can be incredibly powerful—let them hand tissues to crying family members. It normalizes sadness and gives them a sense of helping during a difficult moment.
After:
Give them time with the pet’s body if they want it. Let them help choose what happens next—cremation, burial, planting something in the pet’s memory. Being included in these decisions shows them that their feelings matter and their voice is valued.
How to Involve Them (If They Choose Not to Be Present)
Let them say goodbye beforehand in whatever way feels comfortable. Give them a specific job during the euthanasia: “Your role is to take care of [younger sibling] while we’re saying goodbye to [pet].” After, offer to show them the pet’s body if they want to see it—some children do, some don’t, and both choices should be respected. Include them in memorial planning even if they weren’t present for the euthanasia itself.
What Grief Looks Like
You might notice physical complaints like stomachaches or headaches that have no medical cause, trouble concentrating at school, anger outbursts that seem to come from nowhere, fears about other loved ones dying, or attempting to be “very good” as if perfect behavior could prevent other losses.
What Helps Most
Answer all their questions honestly, even the morbid ones about what happens to the body. Involve them in memorial activities—making a scrapbook, writing a poem, creating art about the pet. Provide books and worksheets about pet loss (resources listed below). Give them permission to have big emotions—sadness, anger, confusion—all of it is valid. And consider notifying their school counselor so teachers can be supportive if your child has difficult days.
Pre-Teens and Tweens (9-12 Years)
By this developmental stage, according to the Palliative Care Network of Wisconsin, children have an adult understanding of death—they know it’s final, irreversible, and universal. They understand biological processes and cause-and-effect relationships in sophisticated ways.
However, they tend to intellectualize death as a defense mechanism against emotions they haven’t yet fully learned to process. They may seem more focused on facts and details than on feelings, and that’s developmentally normal.
What to Say
Include them in the full picture: “The vet says [pet]’s kidneys are failing. That means their body can’t filter out toxins anymore, and they’re starting to feel really sick. The medication helps some, but it’s not going to fix what’s broken. We need to talk about whether it’s time to help them die peacefully, and I want to hear what you think about this.”
Welcome their questions and observations. Children this age are often remarkably observant about subtle changes in the pet’s behavior or condition.
Should They Be Present for Euthanasia?
Most children this age who choose to be present find it valuable and meaningful. They’re old enough to understand what’s happening and often genuinely want to be there for their pet during this final moment.
Offer the choice and respect their decision completely, without any pressure either way.
How to Involve Them
In decision-making:
Ask them what they’ve noticed about the pet’s quality of life lately. Include them in discussions about timing—not giving them the final say (that burden shouldn’t rest on a child), but genuinely valuing their input. Let them have some say in euthanasia plans: home versus clinic, who should be there, when it should happen.
During euthanasia (if they choose):
Let them position themselves wherever they feel comfortable—holding the pet, sitting nearby, standing at the edge of the room. Give them active roles: holding the pet or a specific paw, giving favorite treats beforehand, choosing music or readings, handing out tissues to family members, taking photos if they want them (many children and teens find photos comforting rather than morbid).
Let them ask the veterinarian questions directly. This age group appreciates being treated as capable and intelligent.
After:
Include them in all aftercare decisions—cremation, burial, memorials. Let them take the lead on memorial projects if they’re interested. Give them the pet’s collar or tags if they want them. These tangible items can be surprisingly comforting.
What Grief Looks Like
Pre-teens may try to appear strong or unaffected, then break down unexpectedly when something triggers a memory. Physical symptoms like headaches or stomachaches are common. You might see mood swings, intense focus on activities as a way to avoid feeling, or deep philosophical questions about death and what happens after we die.
What Helps Most
Treat them as capable while acknowledging that this is genuinely hard. Give them tasks and responsibilities that make them feel useful. Don’t force conversation, but make yourself consistently available. Connect them with peers who’ve also lost pets—knowing they’re not alone matters enormously at this age. Encourage journaling, art projects, or physical activities as outlets for processing emotions they might not want to talk about yet.
Teenagers (13-18 Years)
Teens have a complete adult understanding of death, but they’re in a unique developmental stage focused on identity formation, independence, and peer relationships. According to child development researchers, they intellectually understand death while emotionally struggling with the reality that they’re not invincible and that people and pets they love can actually die.
What to Say
Talk to them like the adults they’re becoming: “The vet says [pet]’s cancer is progressing and the pain medication isn’t controlling it anymore. We probably need to make a decision about euthanasia within the next week or two. I want to know what you think and how you’re feeling about this.”
Include them as genuine partners in the decision to whatever degree feels appropriate. They’ll know if you’re just humoring them, and that’s worse than not including them at all.
Should They Be Present for Euthanasia?
Absolutely offer this choice. Research on adolescent grief shows that teens who choose to be present generally report that it helped them process the loss and provided meaningful closure they wouldn’t have had otherwise.
They may also want to be alone with the pet at the very end, or just with one parent rather than the whole family. Respect whatever configuration feels right to them. Their grief is as valid as yours, and they deserve autonomy in how they experience this goodbye.
How to Involve Them
In decision-making:
Include them in veterinary conversations about prognosis and quality of life. Ask for their observations about the pet’s condition—they often notice things others miss. Give them genuine input on timing and logistics. If they want to understand the euthanasia process fully, let them research it themselves or ask detailed questions.
During euthanasia (if they choose):
Let them control their level of involvement completely. They might want to hold the pet close, or they might prefer to sit at a distance with their hand on the pet’s paw. Give them meaningful roles: positioning the pet, giving favorite foods or treats beforehand, playing music they chose, taking photos or videos if desired, writing or reading something to the pet. And yes, even at this age, letting them hand tissues to others or comfort younger siblings gives them a sense of purpose during an overwhelming moment.
Let them ask questions and engage directly with the veterinarian. Teens appreciate being taken seriously.
After:
Let them take the lead on memorial decisions if they want that responsibility. Give them space for private grief while making absolutely sure they know support is available whenever they need it. Don’t be offended if they want to process with friends rather than family—this is developmentally normal, not rejection.
What Grief Looks Like
Expect withdrawal, intense mood swings, throwing themselves into activities to avoid feeling, seeming completely indifferent one moment and devastated the next, anger that seems disproportionate, or deep philosophical questions about life and meaning.
Many teens prefer to talk to friends, school counselors, or online grief communities rather than parents. This isn’t rejection of you—it’s developmentally appropriate. They’re practicing being independent adults who can handle difficult emotions.
What Helps Most
Treat them as capable while giving them complete permission to have any emotional response they have. Don’t force conversation, but make yourself available without hovering. Connect them with peer grief support groups—The Tilly Project has excellent resources for teens. Respect their need for private processing time. Model that it’s okay to be sad while still functioning in daily life. And perhaps most importantly, acknowledge that this loss is genuinely significant—don’t dismiss it as “just a pet.”
Beyond the Goodbye: Supporting Your Child Through Grief
However you’ve chosen to handle the euthanasia itself, your child will need ongoing support through grief. Here are some practical ways to help:
Use quality resources: The Tilly Project (thetillyproject.org/grief-resources-for-children/) provides excellent age-appropriate books, workbooks, and activities for children of all ages. These resources have been carefully curated by professionals who understand childhood grief.
Create memorials together: Planting a tree or flowers, making a scrapbook, writing poems, drawing pictures, creating a shadow box with the pet’s collar and tags—whatever fits your child’s age and interests. These activities provide tangible ways to honor the pet’s memory while processing grief.
Don’t rush to replace the pet: Wait until your child expresses genuine interest in another pet. Getting a new animal immediately can send an unintended message that the deceased pet was replaceable, just an interchangeable object rather than a unique individual who mattered.
Watch for prolonged or complicated grief: Most grief is normal and healthy, even when it looks intense. But if symptoms persistently interfere with your child’s daily life beyond four to six weeks—if they can’t focus at school, have persistent sleep problems, withdraw from all friends —consult your pediatrician or a child therapist. Professional support can make an enormous difference.
Taking Care of Yourself Through This Process
You’re grieving too, and it’s important—actually healthy—to show your sadness and cry in front of your children. According to research from the Child Mind Institute and grief counselors, expressing your own emotions teaches children that grief is normal and that the pet’s life mattered. Children learn how to handle difficult emotions by watching the adults around them, and you’re modeling something crucial: that love and loss are intertwined, and that’s not something to hide.
What matters is remaining emotionally present and available to support your child, even while you’re sad. If you find yourself so overwhelmed that you can’t provide comfort or answer their questions in the moment, that’s when you might step away briefly to compose yourself. But tears? Those teach children that love and loss go together, and that’s a healthy, important lesson.
Seek your own support through friends, family, pet loss hotlines (see resources below), or counseling. The Tilly Project provides resources for adults as well. Taking care of yourself isn’t selfish—it’s what allows you to be present for your children during this difficult time.
Final Thoughts
By being honest, compassionate, and present with your children through this loss, you’re teaching them something profound: that difficult emotions can be faced, that grief is a normal part of loving deeply, and that love matters even when—especially when—loss is inevitable.
There’s no perfect way to navigate your pet’s death with your children. You’ll probably second-guess some of your choices, wish you’d said something differently, or wonder if you handled a moment as well as you could have. That’s normal. What matters most is that you showed up, you told the truth, you let them be part of the process in age-appropriate ways, and you held space for their grief while managing your own.
Your children are learning from you how to love something fully, knowing it won’t last forever. That’s one of life’s most important lessons, and you’re teaching it during one of its hardest moments. You’re doing better than you think you are.
