The Science Behind the Impact of Hairy’s Visits
When a child enters a hospital, their world changes instantly. Fear, uncertainty, pain, and isolation can quickly replace the comfort and safety of home. In these moments, something as simple as a gentle dog can create an extraordinary shift in a child’s emotional state.
Research consistently shows that therapy dogs have a powerful and measurable impact on hospitalized children.
In a randomized clinical trial published in JAMA Network Open, researchers studied children in a pediatric emergency department who spent approximately ten minutes interacting with a therapy dog. Anxiety was measured using a standardized scale before the interaction and again afterward. The study found that children who interacted with the therapy dog experienced a significantly greater reduction in anxiety compared with children receiving standard care alone.
In fact, 46 percent of children who interacted with a therapy dog experienced a clinically meaningful reduction in anxiety compared with 23 percent of children who did not interact with a dog.

The emotional change can be immediate.
research also reveals something equally important about these interactions.
Children who moments earlier were frightened, withdrawn, or overwhelmed frequently begin smiling, laughing, and engaging with staff and family. Therapy dogs provide a unique form of emotional connection that medical treatment alone cannot provide.
Scientific research also shows that interactions with therapy animals produce measurable biological responses in the body. Studies have documented decreased cortisol levels, which is the body’s primary stress hormone, and increased oxytocin levels, often referred to as the bonding hormone. These physiological changes help explain why children often feel calmer, safer, and more emotionally supported during therapy dog visits.

The emotional benefit created by a therapy dog visit, while powerful, can be temporary. In the same clinical research examining therapy dog interactions, anxiety levels were measured again later in the hospital visit. Researchers observed that while the therapy dog produced a rapid improvement in emotional wellbeing, the difference between groups became less significant as time passed.
In simple terms, the comfort spike created by the therapy dog interaction gradually faded after the visit ended.

Quick Emotional Bonds
Researchers also note that children often form quick emotional bonds with therapy animals. In hospital environments where children may feel isolated, vulnerable, or separated from their normal lives, therapy animals can become a powerful source of comfort and emotional stability. Because of this bond, some studies have documented that patients may experience sadness or disappointment when therapy animal visits end, highlighting just how meaningful those interactions can be.

At Hairy’s Dog House, we recognized this emotional reality from the very beginning.
When the organization was formed, we understood that while therapy dog visits create an incredible spike in joy and comfort, many programs end the moment the dog leaves the room. We never wanted a child’s experience with Hairy to conclude with the emotional drop that can follow the loss of that comfort.
Because of this, the Hairy Sensory Comfort Animal Program was intentionally built into the foundation of Hairy’s Dog House from the very beginning, making our approach different from all other therapy dog programs.
Every child who meets Hairy receives a specially designed sensory stuffed version of Hairy to keep.
These sensory comfort animals were created to maintain the emotional connection and extend the comfort children experience during Hairy’s visit long after he leaves the hospital room. Instead of simply remembering the moment, the child has a companion they can hold, hug, and turn to during moments of fear, anxiety, or loneliness.
This approach is also supported by research in pediatric psychology on what are known as transitional comfort objects. Studies show that children often use comfort objects to help regulate stress and maintain feelings of safety after supportive interactions. These objects help children carry emotional reassurance with them when the original source of comfort is no longer physically present.

Emotional Reality
emotional connection
Hairy’s visit creates an immediate spike in joy, comfort, and emotional connection. The sensory comfort animal helps sustain that sense of safety and companionship in the hours, days, and sometimes even months that follow.
This is what makes Hairy’s Dog House unique.
Hairy does not simply visit children.
He leaves behind comfort that stays with them.
Through this approach, Hairy’s Dog House continues its mission of spreading
