Stress research in therapy dogs reveals animals' needs

Researchers investigated four trained therapy dogs and found no stress during group therapy. The study established that freedom relaxes the dogs, reducing cortisol levels, and symptoms of stressed dogs include hair loss and anxiety-like behaviors. Regular supervision is recommended for therapy dogs to ensure their well-being.
