Poodles can come in a variety of sizes, distinguished by adult shoulder height.
FCI (Federation Cynologique Internationale) recognizes four sizes of one breed: Standard Poodle, Medium Poodle , Miniature Poodle and Toy Poodle. But non-FCI kenel clubs generally recognize three sizes - Standard, Miniature and Toy, sometimes as sizes of the same breed and sometimes as separate breeds.
The terms "royal standard", "teacup" and "tiny teacup" are marketing names and are not recognized by any major kennel club.
