What is the IWDR?

About IWDR

The International Working Dog Registry (IWDR) is an online registry where dog owners can add, edit, and view electronically stored records on their dogs. The registry enables storing ancestral records for as many generations into the past as users are willing to enter data. It also includes the ability to store both health and work performance information on individual dogs. These health and work performance measurements are known as phenotypes.

Purely based on these phenotypes, one can make breeder selection decisions in several ways. The traditional process used for centuries has molded and shaped ancestral dogs into today’s modern breeds. As practiced today, this process involves measuring the important aspects of health, behavior, and performance on each young dog and its relatives, including littermates, full- or half-sibs, parents, grandparents, and even more distant ancestors, when possible. With this information in hand, phenotype selection requires the breeder to somehow put ALL these measurements into context to decide among alternative young dogs exactly which ones will be kept for breeding.

Selection using EBVs is a more advanced selection method. It uses the same phenotype measurements described above for aspects of health, behavior, and performance, but it then combines those measurements in a second step that includes pedigree relationships. The numeric value produced by this second step estimates each dog’s relative genetic worth as a breeder for a particular trait or characteristic. These estimates are known as estimated breeding values (EBVs), and they are the most accurate way known to describe the genetic potential of each young dog as a possible breeder. Key to producing accurate EBVs is to begin the process with accurately recorded pedigree relationships and accurately measured phenotypes on most dogs in a population.

The Terms of Service for accessing IWDR have been written to be as accommodating as possible, while also covering a few very important basic points. Please review them, so you know what is expected of each user.

IWDR is open for use by organizations that breed working dogs in larger numbers. These organizations could be military or law enforcement. They could also be service dogs, guide dogs, search and rescue dogs, or scent detection dogs. If you represent one of these organization types and wish to inquire about enrollment, please fill out our Enrollment Request form.
