Telling Your Kids When Your Dog Has Cancer (And How We Handled Our Family’s News)
The vet called on a Tuesday morning. I remember that because I was standing at the kitchen counter with a half-peeled banana in my hand, and the kids were still in their pajamas, arguing about whose turn it was to feed the dog. Biscuit, our nine-year-old golden retriever, had been limping for a few weeks. We’d assumed arthritis. The vet said it wasn’t arthritis. She said the word “osteosarcoma” slowly, the way you’d say the name of a guest you’ve already forgotten.
I hung up, finished peeling the banana, and said, “Hey, can you both come over for a second?”
I had no idea how to do this. I just knew I didn’t want them watching me make phone calls and whispering into the next room like something was being hidden from them.
“You know how Biscuit’s leg has been bothering her?” I said. “The vet found something inside the bone. It’s a kind of cancer.”
My seven-year-old son, Liam, had that classic seven-year-old response. He fell very still and asked, “Is she going to die?”
My ten-year-old daughter, Ella, didn’t ask anything. She just looked down at the place on the floor where Biscuit normally lays, then walked back to her cereal.
That was the start of it. And over the following weeks, I looked up a lot of advice, tried some of it, threw out some of it, and slowly figured out what actually works when you have to tell children a truth you don’t want to hold yourself.
Keep it plain. No euphemisms.
My first instinct was to soften everything. “She’s really sick.” “She needs special medicine.” “She’s going to be okay for a while.” But that technique fell apart within about forty seconds, because when a child hears “sick,” they think of the flu. Or a stomach bug. Something with a timeline. They don’t think of a quiet, growing thing that doesn’t follow rules.
I’ve learned it’s better to say “cancer” even if it scrapes your throat to say it. Kids are not comforted by vague language. They get more anxious when adults act like words are dangerous. So we explained it simply: cancer is when cells in the body divide and grow when they’re not supposed to. Sometimes it can be treated, sometimes it can’t. With Biscuit, we could manage her pain for now, and we didn’t know yet how much time she had.
We also had to clarify what “old” means as a concept. Ella said, “But she’s not that old, right?” Biscuit is nine, which in dog years feels like around sixty-five in human terms. I hadn’t planned that lesson for a Tuesday, but we sat there and did the math together.
Split the conversation into small chunks.
The biggest mistake I made at first was trying to get the whole thing done in one big talk. You know the kind—sit on the couch, hold their hands, deliver the news, answer all questions, hug. There’s a version of that that works for big events, but a cancer diagnosis isn’t one event. It’s a season. It’s months of low-grade worry, weird appointments, pills twice a day.
So instead of repeating the research to them every day, we started having five-minute conversations at odd times. Waiting for toast bread to pop. Walking to school. While Biscuit licked water off the kitchen floor. I found that kids bring up cancer at the strangest moments, usually when they’re doing something completely unrelated.
One afternoon, Liam was drawing a rocket and said, “Are you going to cry when Biscuit dies?”
That question hit me differently than his first one. It wasn’t about explaining life and death. It was personal. He was checking whether he was allowed to be afraid of watching his parents unravel.
I told him the truth: “Yeah. I probably will cry sometimes. Crying doesn’t mean something’s broken.” That turned out to be more useful than any carefully prepared speech.
Give them a small job.
There were weeks where the kids didn’t know what to do with their hands. They’d watch Biscuit sleep and look like they were waiting for something terrible to happen. I realized that part of their anxiety came from being completely passive. So we gave them tasks.
Liam became in charge of making sure Biscuit’s water bowl was always full. I’d say that’s ridiculous because a water bowl is the easiest thing in the world to fill, but the ritual mattered. Every morning, he’d take the bowl, wash it, fill it fresh, and place it near her bed. It was a small moment of “I’m helping” instead of “I’m waiting.”
Ella would fill a medicine treats jar. Not hold the medicine itself, just the treats that came after. Every time Biscuit swallows her pain pill, Ella gives her a soft cheddar biscuit. Biscuit has started walking across the house for these treats, and I can’t say who benefits more.
Kids process grief and illness through practice, not conversation. A task gives them a physical routine that matches what’s happening in the house.
Don’t pretend you know the timeline.
The hardest thing to hold inside is “I don’t know.” Our vet gave us broad ranges, but ranges are just math. The kids asked really direct questions: “How many weeks does she have?” “Will she be here at Christmas?” “If I’m at school when it happens, will I get to say goodbye?”
I had to resist the urge to say “she’s fine, we have lots of time.” We don’t know. I told Ella: “We can’t control how many days Biscuit has left. What we can control is making each one comfortable for her. That’s our job now.” It’s not a perfect answer, but it’s an honest one.
We also had to explain that quality of life matters. I told Liam, “Biscuit isn’t going to live forever, but she also isn’t going to be in the kind of pain we can’t fix. We’re watching her closely. When she starts having more bad days than good days, we’ll make a decision that’s kind to her.”
It’s a lot for a seven-year-old to hear, but I’d rather he hear that than the false promise that this is all going to resolve neatly.
Let them see you uncertain.
There is a version of parenting that says you have to be the pillar of strength. I don’t believe that anymore. Not after this. My kids have caught me standing by the window after dinner, just watching Biscuit breathe. Nobody said anything. I didn’t pretend I was looking at the yard. Those moments matter too, because kids learn that sadness doesn’t have to be fixed. Sometimes it’s just there, and you can live near it for a while.
People ask me if this is all too heavy for kids. I don’t know what the answer is. They know Biscuit has cancer, they know death is somewhere in the building, but they also know she still begs for toast crumbs. They know she still groans dramatically when she lies down. The normal parts of her are still there.
Last night, Ella came downstairs while I was giving Biscuit her evening pill. She crouched down and rested her forehead on Biscuit’s shoulder.
“I think she still has good days,” she said.
“Yeah,” I said. “I think she does.”
We don’t know how many of those days are left. We mark them one at a time. That’s the best we’ve got, and so far, it’s been enough.
