The role of pets in child development has sparked ongoing debates, often drawing mixed conclusions from various research studies. While pets are believed to offer numerous benefits to children, recent findings challenge this belief.
A phenomenon known as the "pet effect paradox" suggests that despite popular opinions, children with pets may not always fare better than those without. This article explores the surprising results of a large study on the impact of pets on children’s growth and emotional well-being.

The Common Belief and the “Pet Effect Paradox”
Many of us believe that pets have a profound, positive effect on the emotional and cognitive development of children. This is especially true for families with dogs, as headlines promoting the benefits of having a pet circulate frequently. However, the "pet effect paradox" has become a subject of growing interest. This paradox refers to the contrast between anecdotal experiences and scientific evidence on the psychological benefits of pet ownership.
While pet owners often report feeling better emotionally due to their pets, research studies don’t always show a clear link between pet ownership and improved mental health. This discrepancy suggests that while pets may enrich our lives in various ways, the scientific evidence behind these claims is far from conclusive.
A Groundbreaking Study on Pets and Child Development
A large-scale study conducted by Carri Westgarth and her team at the University of Liverpool sought to understand the impact of pets on the development of children. This study, part of the Children of the 90s research project, involved 14,000 children and adolescents from the UK. It was a longitudinal study, meaning that researchers assessed the same children over several years—from the age of 2 to 15—looking at their emotional, social, and cognitive development.
The study aimed to determine whether children with pets scored better in areas like self-esteem, language development, and academic success compared to those without pets. The researchers considered a range of factors that might influence the results, such as family income, ethnicity, and parental health.
Unexpected Results and Insights
The study’s findings were surprising and somewhat contradictory to common beliefs. After controlling for confounding variables like family wealth and education, the researchers found few positive effects of pet ownership on child development. In fact, in some cases, children with pets showed poorer outcomes compared to their peers without pets.
For example, there was no significant evidence linking pet ownership with improved emotional health. Contrary to what many people believe, having a pet didn’t appear to benefit children’s emotional well-being. Behavioral problems were also found to be similar between children with and without pets. Interestingly, children with pets were observed to have more issues in six areas of behavioral development.
The Impact on Cognitive and Educational Achievement
In terms of cognitive development, children with pets did not show marked improvements. However, there was one exception: 11-year-olds with dogs had more difficulty shifting attention between tasks. This suggests that pets might have some influence on cognitive processes, but it does not provide substantial evidence of overall cognitive benefits.
The most surprising results came from the area of educational achievement. In the study, children with pets generally performed worse academically than those without pets. For instance, 7-year-olds with pets scored lower in subjects like reading, writing, and math. Similarly, teenagers with pets tended to get lower grades in subjects such as biology, chemistry, and English. Although these differences were small, they were consistent across various age groups.
Understanding the Pet Effect Paradox
The findings from this study add to the growing body of research that questions the widespread belief in the positive influence of pets on child development. Despite popular assumptions, pets do not seem to significantly improve children’s emotional or cognitive health, nor do they guarantee better academic success.
Interestingly, the study’s results align with previous research, including a 2017 study by the Rand Corporation. That study found that when controlling for socioeconomic factors like race and income, differences between children with and without pets disappeared. This suggests that the benefits of pet ownership may be overstated when other variables are not taken into account.
The Takeaway: Pets and Children’s Growth
While pets may provide comfort and companionship, the idea that they universally improve child development is not strongly supported by scientific research. The pet effect paradox remains a complex issue. As Carri Westgarth noted, pets might play a role in fostering social interactions and providing comfort, but they are unlikely to be a cure-all for emotional or developmental challenges.
Although pets can offer emotional support during difficult times, this study suggests that their role in shaping children's cognitive and emotional development may not be as significant as many people think.
