Working Dog Research

Working dogs are specially-trained canines that perform lifesaving and critical tasks to benefit humans and society.

Drawing from the unparalleled wealth of academic, research, and medical resources at the University of Pennsylvania, the Penn Vet Working Dog Center is uniquely positioned to pursue a variety of research, training, and teaching opportunities centered on the working dog.

To improve our nation’s ability to produce, train, and maintain these valuable canine partners, the Working Dog Center conducts cutting-edge research in wide range of areas.

Areas of Research

Physical and Behavioral Health of Working Dogs

Physical & Behavioral Health

Gaining a better understanding of the unique occupational health hazards and special medical and fitness needs of working dogs helps ensure these dogs work longer, healthier lives. This type of understanding also provides information necessary to safely deploy these dogs in their often hazardous working environments. Our program focuses on form and function and gaining a better understanding of how fitness may help improve overall health and performance.

Breeding

Identifying the role genetics plays in the success of working dogs in different disciplines and in the health issues that impact their performance will drive a stronger domestic breeding program increasing the number of qualified dogs that can serve. In the future, combined with behavioral assessments (phenotype), this information will aid selection of breeding animals and ideally dogs from shelters or rescues that have the genetic potential to be successful working dogs. Learn more about our breeding strategies...

Puppy Development

From the time they enter our program at eight weeks of age, our puppies participate in a comprehensive program that uses scientific principles to maximize each dog’s genetic potential. Not only are we focused on developing their olfactory abilities, but we aim to raise well-balanced, environmentally sound dogs.

Detection Training

Applications of the canine’s olfactory abilities continue to expand, and the Working Dog Center is dedicated to exploring ways to improve man’s quality of life through detection. Our dogs train in many disciplines including medical (cancer and infection) detection, antiquities detection, search & rescue, and dual and single purpose law enforcement. The Working Dog Center Training Team collects data on every element of each dog’s training. This data is then analyzed and aids in identifying the most efficient and effective training methods.

Olfaction

An emphasis on sensory health is important to understand factors that might affect the olfaction or other senses critical to the well-being and performance of detection dogs. Our studies aim to improve our understanding of different aspect of detection, such as threshold. We also study risk factors that could impair olfaction including anesthesia, vaccines, opioid exposure and naloxone administration.
