Pre-modern dogs, also known as ancient breeds, primitive breeds, or landrace dogs, possess ancestral traits that can provide insight into the brains and behaviors of early domestic dogs. Despite their relevance to our understanding of dog evolution, pre-modern dogs remain woefully underrepresented in scientific literature, particularly when it comes to their brain anatomy.
In this study, we will compare the brains of pre-modern dogs to those of modern breed dogs and wild, non-domesticated canids. This will allow us to identify what is unique about pre-modern dog brains, as well as shed light on the changes that have occurred in dog brains during different stages of domestication.
Participation involves bringing your dog to Harvard’s Cambridge, Massachusetts campus for a non-invasive MRI brain scan. During the appointment, we will also collect genetic data from your dog using a cheek swab. This will allow us to examine whether there are specific genetic markers or variants that may be associated with the ancestral characteristics of pre-modern dogs.
Furthermore, your valuable input regarding your dog’s behavior, temperament, and training history will be gathered through comprehensive surveys. This information will allow us to determine how brain anatomy relates to cognition, emotion, and behavior in pre-modern dogs.
As a token of our gratitude for your participation, we will provide you with images of your dog’s brain. We will also share preliminary results and copies of publications with you as soon as they become available. During the MRI appointment itself, complementary glaucoma screening, nail trimming, and ear cleaning will be offered.
