The Manchester Terrier is named after the English city where much of the breedโs early development took place. Sleek, racy dogs who possess a terrierโs ratting instinct and the graceful contours of coursing hounds, Manchesters are spirited, bright, and athletic. They combine the streamlined grace of a coursing hound and the instincts of a fearless rat terrier. These racy dogs come in two size varieties: Standard (not exceeding 22 pounds) and Toy (not exceeding 12 pounds).
