Two Separate Brain Networks for Predicting Trainability and Tracking Training-Related Plasticity in Working Dogs.

Functional brain connectivity based on resting-state functional magnetic resonance imaging (fMRI) has been shown to be correlated with human personality and behavior. In this study, we sought to know whether capabilities and traits in dogs can be predicted from their resting-state connectivity, as in humans. We trained awake dogs to keep their head still inside a 3T MRI scanner while resting-state fMRI data was acquired.

Two-temperature preparation method for PDMS-based canine training aids for explosives.

Canine training aids based on vapor capture-and-release into a flexible polymer, polydimethylsiloxane (PDMS), have been used for in canine detection of explosives that have volatile or semi-volatile odorants. To enhance the rate of odor capture for less volatile targets, two temperatures are used for aid preparation. By using an elevated temperature for the target explosive, the amount of vapor is enhanced, increasing the production of the characteristic odor profile.

Development and Training for Working Dogs.

Individual differences in behavior lead to wide variability in working dog suitability, and are the primary reason for rejection or early release. Behavioral suitability of a working dog is shaped by interactions with its environment during early development and specialized training. Understanding how aspects of development and training affect a working dog's performance is critical for practitioners to effectively evaluate and treat behavioral concerns in working dogs.

Validation of a Behavior Test for Predicting Puppies' Suitability as Detection Dogs.

Behavioral characteristics are the most influential factor in the success of a working dog. The need for highly capable detection dogs continues to rise; but reliable methods for early selection are lacking. The current study aimed to assess the reliability and validity of a behavioral test for assessing detection dog suitability.
