How Dogs Improve Mental Health: What the Research Says

Whether it’s the comfort of a wagging tail after a tough day or the way a dog seems to sense your emotions before you speak, there’s something undeniably healing about the human-canine bond. But beyond the warm fuzzies, scientific research confirms what many of us already know: dogs can significantly improve mental health.

From reducing anxiety to easing symptoms of depression and PTSD, dogs provide more than just companionship—they offer powerful emotional support that can be therapeutic, stabilizing, and life-affirming.

The Mental Health Benefits of Dogs

1. Reduced Stress and Anxiety

Numerous studies have found that simply petting a dog can reduce levels of cortisol (the body’s primary stress hormone) and increase oxytocin, the same hormone linked to bonding and relaxation. According to the American Heart Association, dog owners tend to have lower blood pressure and heart rates in stressful situations compared to those without pets.

A 2021 study published in PLOS One found that participants experienced lower perceived stress and anxiety after interacting with therapy dogs for just 10 minutes.

2. Emotional Regulation and Routine

Dogs thrive on routine—walks, meals, and playtime—which can help their humans create structure in daily life. For individuals struggling with depression, anxiety, or trauma, this built-in routine can offer grounding and purpose, especially during periods of emotional dysregulation or isolation.

3. Support for Trauma and PTSD

Therapy dogs and psychiatric service animals are increasingly used to support individuals with post-traumatic stress disorder (PTSD). Research published in Frontiers in Psychology (2018) showed that veterans with PTSD who worked with trained service dogs reported significantly reduced symptoms, including fewer panic attacks and flashbacks, and improved sleep.

Dogs can also serve as a source of neuroception safety—their calm presence can help the nervous system shift out of hypervigilance and into a regulated state, an essential component of trauma healing.

4. Combatting Loneliness and Depression

The Human-Animal Bond Research Institute (HABRI) reports that dog ownership is strongly associated with decreased loneliness and improved emotional wellbeing, especially for individuals living alone or facing chronic illness.

In fact, the CDC notes that pet ownership can lead to increased opportunities for social interaction, physical activity, and emotional connection, all of which are protective factors against depression.

5. Therapeutic Support in Clinical Settings

More therapists and healthcare professionals are integrating Animal-Assisted Therapy (AAT) into treatment, especially with children, trauma survivors, and individuals on the autism spectrum. Dogs can help clients regulate emotion, build trust, and feel more secure in therapy sessions.

How I Incorporate Dog-Informed Insights into Therapy

While I do not currently offer animal-assisted therapy directly, I deeply respect the research on the therapeutic benefits of dogs. In our work together, I help clients:

• Identify sources of comfort and connection, including pets

• Use mindfulness-based strategies that mirror the calming, grounding presence animals provide

• Explore routines and relationships that promote emotional regulation

• Process grief around pet loss or transitions

• Build stronger attachment patterns through the lens of secure, unconditional connection—something dogs offer naturally
