Poodle throughout, although most AKC-registered show dogs have a lion-cut or other, similarly shaven look. The sizes of the official AKC-recognized Poodle breeds are determined by height, not by weight. Poodles are bred in a variety of sizes, distinguished by adult shoulder (withers) height. The exact height cutoffs among the varieties vary slightly from country to country. The Fédération Cynologique Internationale (FCI) recognizes four sizes of one breed: standard, medium, miniature, and toy. Non-FCI kennel clubs generally recognize three sizes, standard, miniature, and toy, sometimes as sizes of the same breed and sometimes as separate breeds. Only the FCI describes a
Dog anatomy "star" of white fur on their chest or undersides. A study found that the genetic basis that explains coat colors in horse coats and cat coats did not apply to dog coats. The project took samples from 38 different breeds to find the gene (a beta defensin gene) responsible for dog coat color. One version produces yellow dogs and a mutation produces black. All dog coat colors are modifications of black or yellow. For example, the white in white miniature schnauzers is a cream color, not albinism (a genotype of e/e at MC1R.) Modern dog breeds exhibit a diverse array
