Working Dog Research & Breeding


Our comprehensive research program leverages the canine physiology, sports medicine, cognition, behavior, development and genetics expertise of our team and our collaborators to optimize the health and performance of detection dogs

Our Center serves as a resource for investigating important research questions raised by operators, trainers, agencies, scientists and clinicians. If you are interested in a sponsored research project or collaborating on a study, please contact Dr. Otto at cmotto@vet.upenn.edu

The three main areas of research include:

  1. Canine Sports Medicine
  2. Olfaction
  3. Cognition and Development

What Do You Think? Can Dogs Detect COVID-19?

We think they can, but we want to prove it and we need your help.

  • Help us prove that dogs can sniff out COVID-19

    The Penn Vet Working Dog Center is looking for individuals in the United States tested for COVID19 SAR-CoV2 by nasal swab or sputum test to assist in our research study to determine if dogs can detect COVID19.

    We are seeking individuals over 18 years of age who either will be tested or have been tested and have received results (positive or negative) in the past 24 hours.

    Eligible participants will be asked to complete a brief health survey, then eligible participants will be sent a cotton T-shirt to be worn one night while sleeping. The T-shirt will be packaged and shipped back to the Penn Vet Working Dog Center to be used in training and testing the dogs.

    This study may help us identify a unique odor associated with COVID19 infection and guide novel screening methods.

Areas of Research

Physical and Behavioral Health of Working Dogs 

Canine Sports Medicine

Sports medicine encompasses all aspects of health and performance of working dogs with an emphasis on clinical and operational outcomes. Our Canine Sports Medicine Residents, Masters of Translational Research candidates, post-doctoral fellows and research associates work together with government, industry and academic collaborators.

Current research focus:

  • Canine Fitness
  • Occupational Hazards of Working Dogs
  • Hydration Strategies

Canine Olfaction

The working dog center is focused on olfactory detection, factors that impact performance as well as proof of concept of ways in which the detection ability of dogs can be applied to solve “One Health” problems including diseases of humans and animals, and environmental threats.

Key areas of investigation:

  • Medical detection: Ovarian cancer, Biofilm infections, COVID-19, Sinonasal papilloma, Chronic Wasting Disease in Deer
  • Environmental detection: Spotted Lanternfly detection
  • Olfactory function: Naloxone, Bordetella vaccination, exercise, threshold detection

Detection Training at the Working Dog Center 

Cognition & Development

The shortage of detection dogs in the US has raised awareness of the importance of breeding, raising and selecting dogs that have both the physical and the behavioral capacity to succeed in detection careers. As part of a national initiative, the Penn Vet Working Dog Center is actively researching the genetic, developmental and cognitive factors that contribute to success of working dogs.


Breeding Program

Understanding and optimizing the interaction between nature (genetics) and nurture (the raising/training environment) is critical for the breeding, raising and selection of successful working dogs to meet the needs of our country.
