Study: Therapy Dogs Enjoy Their Work

Humans really don’t deserve dogs. A new study published in the journal Applied Animal Behavior Science looked at 50,000 therapy dogs currently working in the U.S. The researchers took samples of the dogs’ saliva, and tested it to find how high the animals’ levels of the stress hormone cortisol were both at home and in their working environment. The findings were remarkable– there was no difference in how much cortisol the dogs had at home versus at work. This is considered evidence that the animals are not particularly stressed when working. The researches also analyzed 26 canine behaviors and discovered the animals rarely showed behavioral signs of stress while on the job. This all suggests the animals might actually enjoy helping out humans in need.
