Description of Research Expertise

Current Research Interests are focused on the health, genetic and behavioral aspects of performance in detection dogs. I have been following the health and behavior of the search dogs following the 9/11 response. We have established the AKC CAR Detection Dog DNA Bank to study the genetics of complex behavior. We have a DOD funded field study of the effect of different hydration strategies on performance, hydration, and inflammation in detection dogs. Opening Sept 11, 2012, the Penn Vet Working Dog Center will integrate the science and field experience to breed, select, raise and train dogs to use their noses to detect things (e.g. explosives, drugs, people, and even cancer and infectious diseases). The Penn Vet Working Dog Center will be a resource for behavioral, nutrition, development and conditioning studies in dogs being trained for detection work. In addition, the interactions between dogs and humans will be studied, focusing on 3 major groups of volunteers/interns working with the program: homeless youth, veterans, and parolees from prison dog raising programs.

In addition, clinical research in emergency care of dogs and cats, sepsis and trauma continue to be of interest.

Keywords:

dog, performance, genetics, DNA bank, behavior, olfaction, development, hydration, working dogs, reproduction,

Previous Research Focus
-Regulation of nitric oxide synthesis.
-Intermittent hypoxia as an inflammatory stimulus.
-Acute lung injury

Previous Research Summary:

The effects of intermittent hypoxia on regulation of inflammatory mediators, acute lung injury and nitric oxide synthesis was the main interest of the laboratory, but the laboratory is no longer actively pursuing this direction.

Possible Lab Rotation Projects:

none currently available; however field research at the Working Dog Center is possible.

Description of Itmat Expertise

Dr. Otto is interested in naturally occurring diseases, (particularly sepsis and inflammation) and behaviors (learning, focus, olfaction) in dogs and how clinical investigations in this population can facilitate new therapies and new understanding of health and performance for humans and animals.
