Methods: This prospective study analyzed variance and inter-rater intraclass correlation coefficients (ICC) of agreement within BCS and MCS assessments collected from the 43 EDDs by four blinded graders; the EDDs' respective handler and three veterinarians with varying levels of veterinary expertise.

Results: The results of the study showed that 74.

Development of a modified C-BARQ for evaluating behavior in working dogs.

Introduction: Current high demand for effective odor detection dogs calls for the development of reliable methods for measuring performance-related behavioral phenotypes in these highly specialized working animals. The Canine Behavioral Assessment & Research Questionnaire (C-BARQ) is a widely used behavioral assessment tool among working dog organizations with a demonstrated ability to predict success/failure of dogs in training. However, this instrument was developed originally to study the prevalence of behavior problems in the pet dog population, and it therefore lacks the capacity to measure specific behavioral propensities that may also be important predictors of working dog success.

Dogs can detect an odor profile associated with biofilms in cultures and biological samples.

Introduction: The study investigated the utilization of odor detection dogs to identify the odor profile of biofilms in pure samples and in biosamples from animals and humans with periprosthetic joint infection (PJI). Biofilms form when bacterial communities aggregate on orthopedic implants leading to recalcitrant infections that are difficult to treat. Identifying PJI biofilm infections is challenging, and traditional microbiological cultures may yield negative results even in the presence of clinical signs.

Assessing Different Chronic Wasting Disease Training Aids for Use with Detection Dogs.

Chronic wasting disease (CWD) is a highly infectious, fatal prion disease that affects cervid species. One promising method for CWD surveillance is the use of detection dog-handler teams wherein dogs are trained on the volatile organic compound signature of CWD fecal matter. However, using fecal matter from CWD-positive deer poses a biohazard risk; CWD prions can bind to soil particles and remain infectious in contaminated areas for extended periods of time, and it is very difficult to decontaminate the affected areas.

Retrospective evaluation and review of approaches for nonspecific lameness in dogs presented to an emergency service (2013-2014): 134 cases.

Objective: This retrospective study aimed to characterize and evaluate the emergency approach, diagnosis, management, treatment, and follow-up of nonspecific canine lameness cases.

Design: Retrospective case series from September 25, 2013 to September 25, 2014.

Setting: The study was conducted at an urban university teaching hospital.

A 15-year longitudinal study of search-and-rescue dogs identifies the musculoskeletal, integumentary, and gastrointestinal systems as commonly affected.

Objective: A longitudinal study followed search-and-rescue (SAR) dogs for 15 years to determine the incidence of health events and whether factors of deployment during 9/11, breed, or sex altered the risk of specific events.

Animals: 150 SAR dogs: 95 dogs deployed to the September 11 terrorist attack sites and 55 SAR dogs not deployed.

Methods: Each year, a survey was sent to the handler to collect health information until the dog died or the handler withdrew from the study.

Pharmacokinetics and pharmacodynamics of intranasal and intramuscular administration of naloxone in working dogs administered fentanyl.

Background: Working dogs exposed to narcotics might require reversal in the field.

Objective: To explore the pharmacokinetic and pharmacodynamic effects of naloxone administered intramuscularly (IM) or intranasally (IN) to reverse fentanyl sedation in working dogs.

Animals: Ten healthy, working dogs aged 1.

The Effects of Fitness Training on Working Dog Behavior: Two Case Studies.

Working dogs perform complex tasks that require both physical and behavioral soundness. Two case studies demonstrate how fitness training moderated arousal levels, facilitated training, and improved performance measures in different situations. Fitness training can be beneficial when integrated as part of a working dog's training regimen because it can have a significant influence on their overall health, behavior, and ability to perform their working role effectively.

Machine learning prediction and classification of behavioral selection in a canine olfactory detection program.

There is growing interest in canine behavioral research specifically for working dogs. Here we take advantage of a dataset of a Transportation Safety Administration olfactory detection cohort of 628 Labrador Retrievers to perform Machine Learning (ML) prediction and classification studies of behavioral traits and environmental effects. Data were available for four time points over a 12 month foster period after which dogs were accepted into a training program or eliminated.

Functional measurement of canine muscular fitness: refinement and reliability of the Penn Vet Working Dog Center Sprint Test.

Working, sporting, and companion dogs require muscular fitness to perform their daily tasks, competitive activities, and operational functions effectively and with a low risk of injury. There are currently no methods to measure the muscular fitness of dogs who are not debilitated. Sprint performance is highly correlated with muscular fitness in humans, and various sprint assessments are used to measure performance for sporting and tactical athletes.

Rehabilitation to Return-to-Work for Working Dogs.

This article highlights the differences between working dog careers, unique protocols associated with health care of a working dog and provides a practical guide to creating and managing a return-to-work program. The rehabilitative approach to a working dog consists of four distinct sequential phases: activity restriction, rehabilitation, return-to-work, and maintenance. The timeline through each phase is dependent on the degree of injury, treatment intervention, prior health status of the dog, and compliance of the handler.

Canine detection of chronic wasting disease (CWD) in laboratory and field settings.

Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy that affects both free-ranging and farmed cervid species, including mule deer, white-tailed deer, and elk (, and ). Due to the long incubation period and variability of clinical signs, CWD can expand and spread to new areas before they reach diagnostically detectable levels. Antemortem testing methods currently available can be difficult to obtain and to be applied to the large numbers required for adequate surveillance.

The Use of Biological Sensors and Instrumental Analysis to Discriminate COVID-19 Odor Signatures.

The spread of SARS-CoV-2, which causes the disease COVID-19, is difficult to control as some positive individuals, capable of transmitting the disease, can be asymptomatic. Thus, it remains critical to generate noninvasive, inexpensive COVID-19 screening systems. Two such methods include detection canines and analytical instrumentation, both of which detect volatile organic compounds associated with SARS-CoV-2.

Retention and future involvement in the American Kennel Club Junior Showmanship Program, a youth dog breed conformation competition.

Similar to other organizations that encourage positive youth development, the American Kennel Club (AKC) created the Junior Showmanship program to develop skills and pave a path for the next generation of competitors in canine conformation. Although participants age out of the Junior Showmanship Program when they turn eighteen, the hope is that Juniors will continue to be active in dog sports into adulthood. Females are overly represented in all age groups in this survey and in current participation.

Effects of Intranasal and Oral Vaccination on the Behavioral and Olfactory Capabilities of Detection Dogs.

The bacterium is responsible for serious respiratory disease in dogs, most often associated with 'kennel cough' (canine infectious tracheobronchitis). It is recommended that dogs are vaccinated against the bacterium every 6-12 months, either by oral or intranasal administration. Any impairment of dogs' olfactory capabilities due to medical treatments may impact their efficiency and accuracy in their jobs.

Canine Mobility Maintenance and Promotion of a Healthy Lifestyle.

This article highlights the recommendations and considerations for maintaining a healthy canine lifestyle. A key component of a healthy lifestyle is the enhancement and optimization of mobility. Mobility is essential in maintaining a high quality of life and involves the interplay of a dog's structure, posture, body condition score, physical exercise, and a healthy human-animal bond throughout a dog's lifetime.
