How far these Rat Terrier names can be trusted

Four places, not the whole country

Only four US registers publish each dog's name and breed together. 81% of these Rat Terriers are licensed in New York City, so the list leans towards New York tastes. Many owners never license their dog, so this is a large sample of licensed dogs, not a census.
