We need to preserve not just the animals but also their gene pools, including those of land races, ancestral breeds, and village dogs that are the living reservoirs of canine genetic diversity. We need to document the breeds of the world and their current population sizes and genetic status, and we need to create the kinds of monitoring and development programs already in place for other domestic breeds of importance. We need to train breeders in the methods of sustainable breeding and provide them with the expertise and tools they need to be "preservation breeders". We will need scientific expertise, computer and database technology, the cooperation of thousands of breeders around the world, and funding. Instead of breeding for perfection and purity, the most important - and urgent - consideration of breeders should be preservation.
