TheManchester Terrier is abreed ofdog of the smooth-hairedterrier type. It was first bred in the 19th century to control vermin, notably rats, at which it excelled. So efficient at the task was it that it often appeared inrat-baiting pits until that sport, which had effectively been illegal in the UK since 1835, finally died out at the beginning of the 20th century.
The breed is generally healthy, although dogs can be affected by several inheritable genetic disorders. A crash in the number of registered Manchester Terriers following the Second World War has resulted in theKennel Club categorising it as a vulnerable native breed, in danger of extinction.
The Manchester Terrier was developed from theBlack and Tan Terrier and theWhippet.[1]. Writing in the early 16th century,John Caius describes a Manchester-terrier type of dog inDe Canibus Britannicis,[a] and at the beginning of the 19th centurySydenham Edwards described what he called a Manchester Terrier in hisCynographia Britannica.[2]
The Black and Tan Terrier had an almost legendary status as a rat killer, an ability that was much prized in overcrowded and rat-infested cities such as 19th-century Manchester. The sport ofrat baiting, in which a terrier was thrown into an enclosure filled with rats, and timed to see how long it took the dog to kill them all, had become popular by the early 19th century along withrabbit coursing. In an effort to produce a dog that could excel at both sports, the breeder John Hulme decided to cross a Black and Tan Terrier with aWhippet.[3] Similar dogs were bred in various other parts of England, but by 1860 Manchester had become the breed centre for these new terriers, and so they became known as Manchester Terriers. Other breeds, including theItalian Greyhound and theDachshund, may also have been introduced into the bloodline.[4]
The Manchester Terrier gained the nickname of the Gentleman's Terrier inVictorian times, because of its dignified demeanour.[5]
By the early 19th century a closer facsimile to the current Manchester terrier had evolved. InThe Dog in Health and Disease by J. A. Walsh, a full chapter was devoted to the black and tan, for the first time recognising it as an established breed. The description given by Walsh is still relevant: Smooth haired, long tapering nose, narrow flat skull, eyes small and bright, chest rather deep than wide, only true colour black and tan.
Some terrier breeds have a reputation for being "stoic and dour", but such terms do not apply to the intelligent and inquisitive Manchester Terrier, who is as "feisty and affectionate" as he is "courageous and tough", and makes a "loyal, eager-to-please" companion.[6]
TheCanadian andAmerican Kennel Clubs recognise two varieties of Manchester Terrier, the original and a miniaturised variant, theToy Manchester Terrier. The latter was recognised as a separate breed by the American Kennel Club in 1938, and is still considered to be a separate breed by the British Kennel Club, theEnglish Toy Terrier (Black & Tan).[7] Where the Manchester Terrier may have button ears, erect ears, or cropped ears, the Toy Manchester Terrier only has erect ears.[8] Other than the size difference and ear type, the Manchester Terrier and the Toy Manchester Terrier have the same overall appearance. Since 1958 the American Kennel Club has considered both to be varieties of the same breed.
According to the Kennel Club's Purebred Health Survey, carried out in 2004, the Manchester Terrier has a median lifespan of around 12 years 10 months. Slightly more than 31 per cent of the animals whose deaths were reported in the survey died of old age.[9] There are some recognised health problems in the breed associated with inheritable genetic mutations.
Glaucoma is a fairly common genetic condition in several breeds of terrier,[10] including the Manchester Terrier. Secondary glaucoma, also known aslens luxation, is caused by excessive pressure within the eyeball forcing the lens of the eye out of alignment. The only effective treatment for this condition is surgical removal of the lens.[11]
Von Willebrands disease is a blood-clotting disorder that affects humans and several breeds of dog, including the Manchester Terrier. The genetic mutation occurs in both the standard and toy varieties, but is seen more commonly in the toy.[12] In the Manchester Terrier the gene isautosomal recessive, meaning that for any offspring to be affected the faulty gene must be carried by both parents. Affected dogs are prone to nose bleeds and bleeding from the gums.[13] DNA tests are available to check for the condition, and the Kennel Club maintains a register of the results of those tests, allowing breeders to avoid breeding from affected dogs.[14]
At the end of the Second World War in 1945 there were only 11 Manchester Terriers registered with the Kennel Club, but thanks to the efforts of the British Manchester Terrier Club, formed in 1937, and others, the breed was saved from extinction.[1][15] The Kennel Club has nevertheless classified the Manchester Terrier as a vulnerable native breed.[b] Between 2017 and 2021, an average of 177 births per year were registered.[16]
