Identify Your Breyer (IDYB) is a free reference website created in 2001 by longtime collector Janice to help people identify and learn about Breyer model horses. It describes itself as a comprehensive online source covering new and vintage models, with photographs and information on known releases, molds, colors, and markings. Visitors can browse models by scale and series, from Traditional and Classic horses to Stablemates, Mini Whinnies, and other collections. The site also covers companion animals, tack, accessories, ornaments, buttons and pins, books, catalogs, crafts, activity sets, and Breyer’s Just About Horses magazine.

IDYB offers guidance for identifying a model by its size, mold shape, and release details, along with resources on specific series, new and discontinued models, and buying or selling collections. It does not provide appraisals, but points collectors toward ways to research current values. The site is maintained as an independent hobby resource, is not sponsored by Breyer, and welcomes corrections and additional information.
