When a family pet dies, adults often underestimate how deeply it affects children. While some kids cry openly and want to talk about it, others might not show obvious signs of grief at all — which doesn’t mean they aren’t hurting. Children process loss differently to adults, and their grief can show up in ways you might not expect.
Here are five common signs that your child is grieving a pet, along with practical things you can do to help.
1. Changes in Sleep Patterns
Grief can disrupt sleep in several ways. Your child might have trouble falling asleep, wake up during the night, or start having nightmares. Some children may want to sleep more than usual as a way of escaping their feelings. If the pet used to sleep in your child’s room, the absence can make bedtime feel especially lonely and unsettling.
What you can do: Maintain a consistent bedtime routine and offer extra comfort at night. A soft toy, a night light, or a photo of the pet nearby can help. If nightmares persist, talk through them gently during the day — sometimes just knowing that bad dreams are normal can ease a child’s anxiety.
2. Withdrawal from Friends and Activities
A child who is normally social and active may suddenly want to stay home, avoid friends, or lose interest in hobbies and sports they previously enjoyed. This withdrawal is often their way of creating space to process difficult emotions. They may also feel that nobody else understands what they’re going through.
What you can do: Don’t force social interaction, but gently encourage it. Let your child know that it’s okay to feel sad and still do things they enjoy. Sometimes a quiet walk together or a simple activity at home can be more helpful than a busy social outing. Give them time, but watch for prolonged isolation lasting more than a few weeks.
3. Anger or Irritability
Anger is a very common part of grief, but in children it can seem confusing or misdirected. Your child might lash out at siblings, become frustrated over small things, or express anger at the vet, at you, or even at the pet for “leaving” them. Younger children especially may not have the vocabulary to express sadness, so it comes out as frustration instead.
What you can do: Try not to take the anger personally. Instead, help your child name what they’re feeling: “It sounds like you’re really angry that Max is gone. That’s a normal feeling when we lose someone we love.” Giving the emotion a name can help a child feel understood and start to work through it.
4. Regression to Younger Behaviours
It’s not uncommon for grieving children — especially younger ones — to temporarily return to behaviours they had outgrown. This might include thumb-sucking, bedwetting, baby talk, clinginess, or wanting to be carried. These regressions are a sign that your child is feeling emotionally overwhelmed and is seeking security and comfort.
What you can do: Respond with patience and warmth rather than frustration. This is not the time to correct or discourage these behaviours. Offer extra physical affection — hugs, holding hands, sitting close while reading together. As your child begins to feel safer, these behaviours will usually fade on their own.
5. Asking Repeated Questions About Death
Children often process big concepts through repetition. Don’t be surprised if your child asks the same questions over and over: “Why did Coco die?” “Where did she go?” “Will you die too?” This isn’t a sign that your previous answers weren’t good enough — it’s how children make sense of something that feels too big to understand all at once.
What you can do: Answer patiently each time, keeping your responses honest and consistent. If your child asks whether you or they will die, reassure them gently without making promises you can’t keep. Something like “Most people live for a very, very long time” can offer comfort without being dishonest.
