The focus of this paper is to outline the issues surrounding the endangerment and possible extinction of a number of equine breeds, primarily the Newfoundland Pony. When comparing the current population numbers of the Newfoundland Pony to other endangered wild animals, the Giant Panda, Grizzly Bear, Mountain Gorilla and Siberian Tiger all outnumber this equine breed, as such the Newfoundland Pony is listed as critically endangered and will be used throughout as a reference to current issues impacting the sustainability of many other equine breeds.
