The companionship of dogs helps kids undergoing cancer treatment

Although survival rates for children diagnosed with cancer have increased dramatically over the past 40 years, hard evidence of proven psychosocial benefits to improve quality of life among patients and families during treatment has remained elusive.

Many hospitals have therapy dogs who visit with patients, and anecdotal evidence underscores the positive impact these programs have on children with cancer and their families.

Preliminary findings from a new, multi-center trial provides some of the first quantitative data to validate these claims.  The study, to be presented at the American Academy of Pediatrics (AAP) National Conference & Exhibition in Washington, DC, collected data on blood pressure, pulse rates and anxiety levels of children before and after a weekly visit from a therapy dog. During the visits, children pet or talk to the dog, brush its fur, view the dog’s photos, watch the dog practicing tricks or commands, and learn about dog breeds.

Preliminary findings show that blood pressure readings in the group receiving animal-assisted interventions remains more stable across all sessions than in the control group, said lead researcher Amy McCullough, Ph.D., National Director of Humane Research and Therapy for the American Humane Association. Similarly, there was a higher degree of variability in heart rate within the control group patients than with the treatment group patients.

“These findings suggest that the dog may have a calming effect on the patient,” Dr. McCullough said.

In addition to the effects on pulse and heart rate to date, preliminary results indicate the canine encounters appear to improve anxiety levels among parents. Parents in the control group report fluctuating anxiety levels with peaks and valleys; parents in the treatment group show more consistency in anxiety levels, and even a small decline in anxiety levels by the end of their participating in the study. Overall, children in both groups saw a decrease in anxiety over the course of their study enrollment. Researchers are also gauging the therapy dogs’ temperament and behavior during the visits.

“This study will be a milestone in understanding of the benefits of the vital bond shared between people and animals,” Dr. McCullough said.

Can people make their pets happy?

Researchers from Nestlé Purina Petcare are conducting some of the first studies of their kind into how external stimuli can generate joyful emotions in dogs.

While scientific evidence demonstrates that owning a pet can help lower people’s blood pressure, and reduce anxiety and depression, less is known about whether human contact has a similarly beneficial effect on animals’ emotional wellbeing.
A technique being used in this research is thermal imaging:  as blood flow changes to a part of the body, the temperature will also change.

Researchers use a thermal camera to measure these temperature fluctuations in pets’ eyes, ears and paw pads.

“Scientists have known for years how to evaluate negative states such as stress and anxiety in animals,” said Ragen T.S. McGowan, Nestlé Purina Petcare behaviour scientist. “Less is known about how to measure positive states such as happiness or excitement.”

“Thermal imaging has been widely used in animal welfare studies, to assess inflammation in racehorses, for example, or to see how certain conditions affect livestock’s stress levels,” she continued.

“This is one of the first times it being used to measure positive responses in pets.”
