Lesson 2: Evidence Based Research on the Impact of School Dogs.

The Science Behind School Dogs

School dogs are becoming an increasingly common sight in UK classrooms—and for good reason. This lesson explores the scientific research and expert insights that explain why dogs can be so beneficial in educational settings. From improved emotional wellbeing to better academic outcomes, the presence of a well-trained, well-cared-for dog can make a profound difference to both students and staff.

Emotional and Psychological Benefits

Research has consistently shown that interaction with dogs can reduce stress and promote emotional regulation. Simply petting or sitting near a calm dog can lower cortisol (the stress hormone) and boost feelings of calm and safety. One 2011 study by Barker et al. demonstrated that therapy dogs helped reduce exam-related anxiety in children—a powerful example of how dogs can support mental health during challenging school moments.

The benefits go beyond stress relief. When people spend time with dogs, their bodies release oxytocin, dopamine, and serotonin—neurochemicals associated with happiness, connection, and trust. According to Beetz et al. (2012), these hormonal shifts can increase feelings of wellbeing and social connection, which are vital in a school setting.

Staff, too, benefit from canine companionship. A 2002 study by Allen et al. found that employees in pet-friendly workplaces experienced less stress and greater job satisfaction. Similarly, in schools, a dog can provide a moment of calm, emotional relief, or simply a reason to pause and breathe.

Importantly, school dogs also help combat loneliness—a common but often overlooked issue. Wood et al. (2005) found that young people who interacted with dogs felt less isolated and more socially connected.

Social and Behavioural Improvements

Dogs can act as neutral, calming presences that help students interact more easily with others. For students with autism or social anxiety, school dogs often serve as "social bridges." They can help ease tension, making it easier for children to engage in group work, speak up in class, or simply connect with peers.

A 2014 study by Lord et al. found that classrooms with a therapy dog saw an increase in positive peer interactions and a decrease in social anxiety. Dogs provided a shared focus that made human-to-human connection less intimidating.

School dogs also model calm and consistent behaviour—traits that students often mirror. McNicholas and Collis (2000) found that therapy animals helped reduce aggression and foster positive, respectful interactions. As a result, schools report fewer behavioural incidents and improved overall classroom climate when a dog is part of the school community.

Academic Advantages

Dogs don't just help students feel better—they can also help them learn better. In particular, literacy programs that involve reading to dogs have shown remarkable results.

A study by Hergovich et al. (2002) found significant improvements in reading fluency and confidence when children read to dogs in a calm, judgment-free environment. Students were more willing to take risks, practice new words, and read aloud. Treat (2013) later reinforced these findings, showing improved literacy outcomes and higher engagement among students reading with therapy dogs.

In general, students are more motivated to participate in academic tasks when a dog is present. Cutt et al. (2008) showed that even reluctant learners were more active and enthusiastic when a therapy dog was involved in the classroom routine. Hunt et al. (2016) also found that classroom engagement increased significantly in schools with therapy dogs, with students showing better focus and a greater willingness to participate.

Physical Health Benefits

The calming effect of dogs also translates into physical health improvements. Regular interaction with dogs has been shown to reduce heart rate and blood pressure, helping both students and staff remain calm in high-stress situations such as exams or transitions.

Beetz et al. (2012) found that even brief petting sessions could reduce cortisol and increase the release of serotonin and dopamine—neurochemicals that promote physical and emotional balance.

Moreover, while school dogs may not be taken on long walks during the school day, they still encourage more movement and interaction. Whether it's walking the dog during break time or engaging in a short play session, dogs help promote physical activity in ways that feel natural and enjoyable.

Dogs also act as social "icebreakers," helping students form connections with peers and adults alike. Wood et al. (2005) noted that dogs help people feel more open and willing to initiate conversations, which can foster stronger school communities.

Staff Wellbeing and Workplace Culture

While the focus of many studies is on student outcomes, staff wellbeing is equally important—and school dogs can help here too.

Teaching is a high-stress profession, with many educators at risk of burnout. Research by Cohen (2016) found that employees in pet-friendly workplaces reported lower stress and greater collaboration. In schools, a dog can help create a calmer atmosphere, improve staff morale, and even boost teamwork by offering shared positive experiences.

Whether it’s a brief interaction in the staffroom or a structured wellbeing session with the dog, these moments of calm can significantly improve workplace culture and support staff retention.

Conclusion

The science behind school dogs is clear and compelling. From emotional regulation and social bonding to improved academic performance and healthier staff culture, the research overwhelmingly supports the integration of therapy dogs in schools.

But introducing a dog to a school setting is not something to do lightly. The success of a school dog program depends on careful planning, training, and—most importantly—prioritising the wellbeing of the dog. In the next lesson, we’ll explore how schools can implement school dog programs in an ethical, sustainable, and structured way.
