Bred mainly in the Pays d'Auge region, it previously had its own studbook, registered by the Société hippique du trait augeron.[38][3] The status of the subtype has been repeatedly debated because of its origin from Percherons bred in Pays d'Auge, a breeding group that was modified from the original breed standard due to the influence of soil and climate over the years, creating the Augeron type.[40] Augerons are light gray in color, tall, strong, well-built, and energetic.[37][41][42][43] They stand 158–170 cm (15.2–16.3 hands) in height, but those horses bred in Vire are known to be smaller than the standard.[37]
