How pets give your kids a brain boost

Choosing a pet starts with understanding how they fit into the home. Kelly Oakes explores what happens when animals join a family – and their profound impact on children’s development.

Pick up a book from a young child’s bookshelf and you’re more likely to find an animal protagonist than a human one. From very hungry caterpillars to great big humpback whales, children seem universally fascinated by animals. But while characters in a picture book are often far removed from reality, the pets many of us share a home with offer children a more realistic glimpse of the animal world – and a meaningful relationship that influences them in a whole host of other ways, too.

Understanding that relationship may not only help parents choose the right pet for their child, but also give them deeper insights into the factors that make for a truly successful bond.

Many parents intuitively feel that looking after an animal can offer children valuable lessons about caregiving, responsibility and empathy. “It’s really important, especially for young kids, to learn that someone’s perspective might be different from their own,” says Megan Mueller, associate professor of human-animal interaction at Tufts University, US. “That’s an easier lesson to learn, perhaps, with an animal than it is with, say, a sibling or a peer.”

Interacting with pets – and with other people

So, are pets truly at the root of all these benefits, or do we just think they are? Hayley Christian, associate professor at the School of Population and Global Health at the University of Western Australia in Perth, is one of the researchers attempting to unravel cause from effect.

Crucially, it was the dog-facilitated physical activity – such as going on family dog walks – that made the difference.

“We can actually say that children having pets and interacting with them over time in early childhood does seem to cause these added benefits in terms of their social-emotional development,” says Christian, who is also a senior research fellow at the Telethon Kids Institute.

That’s not to say that every family should get a pet – or every child with a dog is better off than those without. Behavioural issues, complex medical needs and the financial burden of caring for an animal can all make life with a pet less than rosy. Families living in housing that is not pet-friendly face further barriers. “I don’t think we’re ever going to get to the point where we recommend that everyone with a kid gets a dog,” says Mueller.

It’s also possible that the pandemic put a stop to one of the ways in which living with a dog can give us a boost. “We get the social benefits from interacting with the dog, but there’s also this way in which animals can facilitate social interaction with other people,” says Mueller. During lockdowns, teenagers might have stuck to their daily dog walks but avoided conversations with other dog walkers, losing out on small moments of social interaction.

Building a strong relationship

When it comes to the positive influence of pets on children, the state of their relationship is key – not just living under the same roof. “Relationship quality seems to be a better predictor of some of these health outcomes than just whether or not you have a pet in the home,” says Mueller.

Time spent with a pet is one factor. If your sibling has a hamster that lives in their room, you’re unlikely to feel very attached to it, for example, compared to a family dog that you walk every day after school.

A child’s age can also help determine how solid their relationship with a particular pet becomes. Children aged between six and 10 develop stronger bonds with animals that are more similar to humans, like cats and dogs, than with biologically far-removed species like birds and fish. But older children, aged between 11 and 14, report being just as attached to less closely-related species – including mice – as they are to their dogs or cats.

Family dynamics also play a part. The Australian longitudinal study saw that children without siblings can especially benefit from pets – perhaps because they sometimes act as a surrogate sibling. “Parents are more likely to allow their child to be independently mobile [for example, run an errand alone] if they went with a sibling or a friend,” says Christian. “And guess what else? A dog.”

When children get to know their pets, it opens them up to a deeper understanding of animals in the wider world. “They tend to learn from their pet, somehow, how to be more understanding, empathetic and responsive to animals in general,” says John Bradshaw, former reader in companion animal behaviour at the University of Bristol, UK, and author of several books on cats and dogs.

“You can have all sorts of imaginary stories in your head about a lion, but until somebody takes you to Africa, you’ll never meet one in the wild,” he says. “But a dog or a cat is there and can teach you about what it’s actually like to be an animal, that animals are not human, they have very special lives that belong to them and not to us.”

What’s more, a child’s relationship with their pet could provide a much-needed link with nature. “To have a real living, breathing, slightly messy animal running around the house is a good way of making those connections,” says Bradshaw.

What do animals think of kids?

Remembering our pets’ wild origins can give us an insight into how they see our families.

Dogs evolved to live alongside humans and have the potential to form very strong bonds with us. Cats, on the other hand, are solitary creatures at heart. Even so, they do seem to regard their human housemates as family. “Our cats greet us by raising their tails and rubbing around our legs – precisely what they do when meeting another cat they know well or consider a family member,” writes Bradshaw in his book, The Animals Among Us.

But whether this kinship translates to children depends on a pet’s own early life experiences.

Both cats and dogs have a brief window – for puppies this is between around eight and 16 weeks of age – where they learn about the sorts of people they might encounter in their lives. “We know that if puppies or kittens have not met children at all by the time they get to six months or so – depending on their underlying temperament – they can display really quite adverse reactions,” says Bradshaw. “That suggests that they don’t really recognise children as human, unless they’ve been introduced to them as part of the humanity package.”

This makes perfect sense when you look at it from the animal’s point of view, he says: “A baby is nothing like an adult human. It’s much smaller, it can’t stand up, it makes very different noises to an adult human, and it smells very different to an adult human.”

Understanding how a pet sees the world is vital to making sure everyone gets along. If a cat urinates on a new cot or pram brought into the house, it’s easy to jump to conclusions. “If you were not sympathetic to the way the cat thinks you might think, ‘Oh, the cat’s just getting cross because I’m going to have a baby, it must know’,” says Bradshaw. “Of course, they don’t know. It’s very often the olfactory environment [the smell of the home] that’s been churned up and the cat’s lost its familiar points of reference.”

Both cats and dogs rely heavily on their noses, so having lots of new smells in the house is like “coming home and finding that someone has painted your walls completely opposite colours,” says Bradshaw. On the flip side, familiar scents can keep them happy. In one trial, Bradshaw and his colleagues put a t-shirt that had been worn by a dog’s owner into their bed. “That familiar smell seemed to work wonders for the dog, they were much more relaxed,” he says.

Not anthropomorphising our pets – meaning, expecting them to think and behave like humans – is especially important when it comes to a child’s safety. “You can never be 100% sure how a dog is going to react in any one given situation,” says Bradshaw. “There’s all sorts of possible things which can trigger the dog into a different mode of behaviour, maybe one that the owner has never seen before.”

Ultimately, each child-pet relationship is unique, with its own quirks, benefits, and pitfalls – and in some ways researchers are only just starting to understand what makes a child’s relationship with their pet mutually beneficial. “The field is really moving towards looking at these more individual differences,” says Mueller.

Meanwhile, children themselves rank pets as some of the most important beings in their lives, seeing their animal companions as a comfort and emotional support, as well as being infallible confidantes for a secret. Some of those benefits “are very difficult to quantify because they’re very individual, and science deals in populations and big numbers,” says Bradshaw. “Just because it’s not very tangible and easily measured, it doesn’t mean it’s not real.”
