The Welsh Stud Book contains registration details of four “types” of Welsh Ponies and Cobs. These types include the Section A Welsh Mountain Pony, Section B Welsh Pony, Section C Welsh Pony (Cob type) and Section D Welsh Cob. Each Section has specific characteristics, but all retain the pony character, versatility and excellent temperament of the Welsh breeds.

There is also a register for Welsh Part-bred animals, who must have a minimum proven 12.5% of Welsh blood in their parentage.
