The Manchester Terrier, commonly known as the Black and Tan Terrier in reference to its historical roots, stands as the oldest identifiable terrier breed with documented lineage traced back to the late 1570s. This distinguished heritage connects modern specimens directly to the ancient Black and Tan Terriers mentioned in early English literature, creating an unbroken chain of breed development spanning over four centuries. The breed's name evolution reflects both its geographic origins and its distinctive coloration, which remains its hallmark characteristic to this day.
Historically known simply as the Black and Tan Terrier, the breed acquired its Manchester designation during the 1800s when the Manchester district of England became the breed's development center. John Hulme, a breeder from Manchester, is credited with refining the breed by crossing the original Black and Tan Terriers with Whippets, creating the sleek, agile Manchester Terrier we recognize today. This strategic breeding program enhanced the dog's speed and elegance while maintaining its formidable ratting abilities. Some historical accounts suggest Italian Greyhounds and Dachshunds may have also contributed to the breed's development, though Whippet influence remains most prominent in the breed's refined appearance.
The breed exists in two distinct size varieties: the Standard Manchester Terrier and the Toy Manchester Terrier. Both varieties share identical breed characteristics except for size and ear type. The Standard variety weighs between 12 and 22 pounds and stands 15 to 16 inches tall, while the Toy variety weighs under 12 pounds and stands 10 to 12 inches at the shoulder. Despite these size differences, all Manchester Terriers are classified simply as Manchester Terrier in registration records, with no variety designation noted on official papers. Both varieties can be born in the same litter, and breeding between the two sizes is permitted, resulting in variable offspring sizes based on genetic inheritance.
Ear types represent another distinguishing feature between varieties. The Standard variety may have naturally erect ears, button ears that fold over at the tip, or cropped ears where the practice remains legal. The Toy variety, however, may only have naturally erect ears according to breed standards. Ear cropping was outlawed in England in 1895, significantly impacting the breed's popularity at that time since cropped ears had been traditional and breeders had not prioritized natural ear quality in their selection programs. This ban forced breeders to focus on developing proper natural ear carriage, ultimately improving the breed's overall ear structure.
In Victorian times, the Manchester Terrier earned the nickname Gentleman's Terrier due to its dignified demeanor and elegant appearance. This refined image made the breed popular among discerning gentlemen who appreciated both the dog's working abilities and its sophisticated looks. Victorian women, desiring a smaller companion version, prompted breeders to develop the Toy variety by repeatedly breeding the smallest Standard Manchesters together. Unfortunately, this practice was initially carried to extremes, producing very small, unhealthy animals weighing as little as 2.5 pounds. Modern Toy Manchester Terriers are much healthier, sounder animals, with breed standards now setting reasonable minimum weights to prevent such dangerous miniaturization. The breed's only acceptable coloration is black and tan, though historical records indicate that white, blue, and red variations appeared in the mid-1800s before being eliminated from breeding programs due to associated health problems.
