Army Trains Dogs to Sniff Out COVID-19


In an unprecedented move to combat the spread of COVID-19, the U.S. Army, in conjunction with the University of Pennsylvania School of Veterinary Medicine Working Dog Center, has initiated a groundbreaking project that leverages the unparalleled olfactory senses of dogs for the detection of the virus.

By training a select group of canines to identify the unique scent signatures associated with the virus, this initiative opens up new frontiers in biosecurity and public health surveillance.

The meticulous training involves using a Training Aid Delivery Device (TADD) to expose dogs to samples from COVID-19 positive patients without endangering the animals or their handlers. This approach not only demonstrates innovative thinking but also highlights the potential of integrating animal capabilities into human health strategies.

As this project transitions from the conceptual to the practical phase, questions about its scalability, effectiveness in real-world scenarios, and the broader implications for public health monitoring systems remain compelling points of consideration.

With the world grappling with the challenges posed by the pandemic, the success of this initiative could mark a significant milestone in the way we understand and respond to viral outbreaks.

Training Methodology

The training methodology for COVID-19 detection dogs involves the utilization of a specialized containment vessel known as the Training Aid Delivery Device (TADD), which safely exposes the animals to human saliva and urine samples from infected patients without direct contact with the virus.

This innovative approach, integral to canine training techniques, ensures that the dogs are trained under the highest safety standards. The TADD is a cornerstone in the training process, allowing for the controlled exposure to the scent of COVID-19 human biomarkers.

This method not only protects the dogs but also ensures the integrity of the training samples. By incorporating the TADD, trainers can efficiently teach dogs to recognize and respond to the scent, marking a critical step in harnessing their natural capabilities for disease detection.

Potential Applications

Having established the methodology behind training dogs to detect COVID-19, we now explore the varied potential applications of this innovative approach in public health and safety contexts.

Deploying dogs in public spaces such as airports, sports stadiums, and border control checkpoints could revolutionize our biosecurity measures. The inherent effectiveness of detection these canines offer, owing to their acute olfactory capabilities, presents a non-invasive, rapid screening method to identify infected individuals before symptoms manifest.

This application not only enhances public safety but also fosters a sense of community and belonging among citizens by ensuring shared spaces remain safe.

The deployment of these trained dogs could significantly mitigate the spread of COVID-19, showcasing a fusion of traditional biosecurity methods with cutting-edge science.

Challenges Faced

Despite the promising potential of using dogs for COVID-19 detection, several challenges and limitations must be addressed to ensure the efficacy and reliability of this innovative approach.

  1. Training difficulties: Not all dogs possess the necessary drive and focus required for the intense and lengthy training sessions, limiting the pool of potential canine detectors.
  2. Accuracy concerns: Ensuring the dogs’ ability to detect COVID-19 with high accuracy and consistency across various environmental conditions and among different individuals poses significant challenges.
  3. Variability in biomarkers: The potential variation in COVID-19 biomarkers among infected individuals may affect the dogs’ detection abilities.
  4. Sustainability: Maintaining the dogs’ training and accuracy over time, especially with the emergence of new COVID-19 variants, requires ongoing evaluation and adaptation.

Biosecurity Contributions

Acknowledging the challenges inherent in training dogs for COVID-19 detection, it is equally important to consider their significant contributions to biosecurity efforts. The integration of these canine teams into public health strategies complements existing measures, enhancing the nation’s resilience against this and potentially future pandemics. This synergy between the rigorous training process and their operational role underscores their invaluable position within biosecurity frameworks.

Past Successes

Historically, dogs have demonstrated remarkable success in detecting diseases such as cancer and diabetes, showcasing their potential in medical diagnostics and biosecurity. This history of achievements provides a solid foundation for their current application in detecting COVID-19, emphasizing both the scientific validity and public acceptance of utilizing canines in such critical roles.

  1. Detection Accuracy: Dogs have reached up to 99% accuracy in identifying specific cancers, underlining their exceptional sensory capabilities.
  2. Public Acceptance: Their non-invasive detection methods have increased societal trust and willingness to participate in screenings.
  3. Adaptability: Successfully trained to detect a wide range of conditions, proving their versatility.
  4. Rapid Results: Dogs offer real-time feedback, significantly reducing the waiting period for diagnostic outcomes, thus accelerating intervention strategies.

Current Research

Current research focuses on the innovative training of canines to identify COVID-19 by detecting specific human biomarkers, a project spearheaded by the U.S. Army and academic partners. This initiative emphasizes the development of rigorous training protocols, aiming to enhance detection accuracy significantly.

The methods employed ensure that dogs can accurately identify biomarkers associated with COVID-19 infections in human saliva and urine, without direct exposure to the live virus. Such precision in training is pivotal, as it ensures the safety of the canines while maximizing their detection capabilities.

The structured training protocols are meticulously designed to harness the natural olfactory abilities of dogs, thereby creating a reliable, non-invasive detection tool that could potentially revolutionize the approach to monitoring and controlling the spread of COVID-19 in various public settings.

Future Prospects

Building on the foundation of rigorous canine training protocols for COVID-19 detection, the next phase focuses on the exploration of broader applications and the potential for integrating these skilled animals into public health strategies.

As we look to the horizon, the following key areas illuminate the path forward:

  1. Enhancement of Training Techniques: Refining methodologies to ensure faster, more efficient training processes for diverse diseases.
  2. Expansion of Future Applications: Investigating the feasibility of deploying detection dogs in various public and private sector scenarios.
  3. Integration into Public Health Monitoring: Developing protocols for the seamless inclusion of canine detectors in existing biosecurity frameworks.
  4. Collaborative Research and Development: Fostering partnerships between scientific communities and canine training experts to innovate and expand the scope of disease detection capabilities.


In conclusion, this pioneering endeavor promises to redefine biosecurity paradigms. It is akin to harnessing the mythical power of Cerberus but for the noble purpose of guarding public health.

As the project transitions from nascent research to potential real-world application, it embodies the synthesis of ancient skills and cutting-edge science.

Challenges notwithstanding, the future beckons with the prospect of deploying these canine sentinels in the vanguard against pandemics. This marks a significant stride in preemptive health security measures.
