The current AKC Breed Standard for the Manchester Terrier states: “The bite is a true scissors bite. Level bite is acceptable. The jaws are powerful with full and proper dentition. The teeth are white and strongly developed.”
The inclusion of “full and proper dentition,” or all 42 teeth, in the Manchester Terrier Breed Standard has been a subject of discussion in our breed for some time, partially because no other Manchester Terrier breed standard worldwide has ever included such a requirement until the American Manchester Terrier Club (AMTC) added it in the 1991 AKC Breed Standard revision. For a breed with origins predating written Standards, this is a relatively recent change.
While we don’t know exactly how important full dentition was to the breed’s founders, it’s clear it wasn’t significant enough to be mentioned in any historical Standards.
When the AKC Breed Standard was revised again in 2020, a proposed addition of faults for missing teeth ignited controversy. The first draft published in the AKC Gazette, originating from the AMTC Breed Standard Review Committee, included the following language: “Any deviation from full dentition is a fault. More than two missing teeth is a serious fault.”
Data Doesn’t Lie
Concerned about how such a change to the Breed Standard might affect our small gene pool, the Health Committees of the American and Canadian parent clubs conducted a first-of-its-kind dentition survey of show and breeding dogs in North America in 2020. At the time, I served as Chair of the AMTC Health Committee, a role I continue to hold today.
The findings were eye-opening:
Only 44% of Toy Manchester Terriers had full dentition.
46% of Toys were missing two or more teeth.
Among those Toys missing teeth, the average number missing was 3.6.
Similar trends were seen in Standard Manchesters, which is no surprise considering they are two varieties of the same breed. In both varieties, bottom teeth were more commonly missing than top, and pre-molars, especially the second pre-molars, were the most frequently absent. As many breeders know, those tiny P1s can be particularly hard to see in small mouths.
Importantly, only three percent of all surveyed dogs had incorrect occlusion (overshot or undershot), indicating that occlusion overall is sound in the breed. No dogs were missing canines, and only ten percent of dogs were missing top or bottom incisors. Overall, breeders have placed more emphasis on ensuring a full complement of incisors and canines as contributors to correct occlusion.
The conclusion of our joint Health Committees was: “There is no evidence at this time that dentition on its own represents a significant health issue for our individual dogs, but how we handle it could become a health issue for our breed if we don’t take care to safeguard our breeding pool.”
Judge with Care, Not a Calculator
Following the publication of the survey results, the AMTC removed the proposed faults for missing teeth in subsequent drafts. The revised breed standard was approved later that year (2020) with no changes to the description of dentition.
A few years later, a December 2023 letter from the American Manchester Terrier Club formally weighed in when it issued the following guidance to Conformation judges:
“With regards to dentition consistent with AKC judging procedures, we strongly urge judges to ask the handler to show the bite. Our breed standard states, “the jaws are powerful with full and proper dentition,” and further references “tight black lips lie close to the jaw.” While it is necessary to check the bite and the sides of the mouth, it is improper to open a Manchester Terrier’s mouth to check for the molars or to expect the dog to stand while teeth are counted. The breed standard does not include a disqualification for missing teeth. Due to the tight lips that lie close to the jaw and the large teeth relative to their size, attempting to handle the dog and visualize each tooth in an exhibit’s mouth can lead to an unnecessarily unpleasant experience for the dog.
When examining the Manchester Terrier from a functional and historical perspective, it is most important to ensure the quality of the bite by evaluating the strength of the jaw, size of the teeth, and the occlusion.”
This guidance was provided at the request of the membership following numerous exhibitor complaints about judges counting teeth during table exams.
Table Manners
There are several important reasons why judges should follow this protocol:
Temperament: The AKC Breed Standard describes the temperament as “discerning.” Manchester Terriers tolerate a quick exam but will often resist prolonged handling by strangers. Aspiring judges are taught to examine Manchesters efficiently: get in and get out.
Table behavior: Manchester Terriers know how long an exam should take and they are counting down in their heads to when that release in pressure will come! While seasoned show dogs can and should be able to tolerate a more thorough exam, puppies and less experienced dogs can be stressed and potentially soured by exams that extend beyond what is customary for the breed.
Physical limitations: The tight lips and small mouths of the Toy variety make it difficult to visualize all of the teeth, especially the tiny first pre-molars. Attempts to do so cause discomfort and accidental lip pinches, which are not soon forgotten by the dog.
Manchester Terriers have long memories, and a negative experience on the table can cause lasting aversion to the show ring. A functional evaluation of the bite should focus on jaw strength, tooth size, and occlusion, not a forensic-style audit of tooth count.
Closing the Jaw on Controversy: A Functional Approach
Missing teeth in the Manchester Terrier are not new, nor is it escalating. Penalizing dogs for a missing premolar—particularly when it has no impact on function or type—risks doing more harm than good. That said, this is not a call to pardon dogs with numerous missing teeth. As with any structural deviation, the degree to which a trait is penalized should be proportional to the extent of deviation from the ideal.
We must preserve the Manchester Terrier’s integrity and utility without compromising genetic diversity. Judges and breeders alike should consider the whole dog: form, function, and temperament—not just a tooth tally.

Is it a coincidence that Shakespeare’s timeless tale about the Capulets and the Montagues hails from the same land and era as the ancestors of a breed whose fanciers have historically been at odds? Today, the American Kennel Club (AKC) recognizes the Manchester Terrier as one breed with two varieties, Toy and Standard, for which there is one parent club and one Breed Standard. It seems rather straightforward, however, just beneath the surface lies a tension that mirrors that other rivalry of British origin. Breed enthusiasts have long debated whether the two varieties are, or really should be, truly one breed. As recently as December 2023, the American Manchester Terrier Club (AMTC) waded into this tumultuous territory when it published a letter that the AKC Judges Education Department circulated to AKC Judges.
Another historical piece, circa 1870s by William Henderson of Belcher and Lady Dot, shows the similarity between two differently sized Black and Tan Terriers.
Breeders, judges and exhibitors should understand that differences in size are a defining feature of the breed. While breeders may express preferences for one size variety over another, it’s important for judges to make placements consistent with the Breed Standard, which was written to reflect the breed’s history and the range of functions.
Before we dive into the fray, let’s lay some groundwork for how the breed is represented in the United States today:
The AKC Breed Standard
The AKC Manchester Terrier Breed Standard states that it is one breed with two varieties, the Standard and Toy, of which the only differences are weight and ear type.
Dogs competing in the Standard variety may have cropped, button or naturally erect (upright) ears. The only permissible ear type for dogs competing in the Toy variety is the naturally erect ear.
Exhibits must be shown in the Toy variety if weighing 12 pounds and under. Dogs weighing over 12 pounds but not exceeding 22 pounds must show in the Standard variety.
Exhibition
The varieties are shown separately and compete for “Best of Variety” rather than “Best of Breed” at most AKC Conformation events. Standalone specialties are the only events where winners of each variety may compete for Best of Breed.
The Standard variety is exhibited in the Terrier Group and the Toy variety is exhibited in the Toy Group.
Judges may weigh exhibits. Dogs shown in the Toy variety are excused for entry in the wrong class if they exceed 12 pounds. Dogs competing as Standards that exceed 22 pounds are disqualified per the Breed Standard.
A dog may begin exhibiting in the Toy variety, but the rules require that it compete in the Standard variety if it later surpasses the 12-pound weight limit for Toys. All awards and titles carry over with the dog.
Registration & Breeding
All dogs are classified as simply “Manchester Terrier” in the AKC stud book and on registration papers, with no variety indicated.
It is permitted to breed a Toy-sized dog to a Standard-sized dog.
Both varieties can be born from the same litter and the final weight of offspring may not be consistent with the variety classification of their parents.
Ok, phew! That’s a lot to digest! For our purposes, though, the important takeaway is this: The AKC views Manchester Terriers as one, single breed. Now that you understand the system, let’s get back to the essential question: Are they truly one breed?

The Great Debate
Some fanciers today cite the unification of the two varieties as a recent development in the breed’s history. It’s true that in the breed’s country of origin, the counterparts to the Toy and Standard varieties were split into separate breeds. (There will be more on that soon.) These fanciers believe that breeders who have favored one size variety over the other have, over time, created genetic siloes between them. They say the result has been such strong differences in type and temperament that they should be considered separate breeds.
Even among those who don’t advocate for splitting the varieties into two separate breeds, there is persistent debate over whether the varieties should be interbred, and whether dogs born from Toy parents should be shown in the Standard ring. Over the decades, many have been discouraged by their peers from exhibiting smaller Standards, especially if they have natural ears. Words like “oversized Toy” tend to get thrown around ringside and judges will frequently use the term when examining smaller Standard specimens, often without understanding the stigma that is attached to this term.
Two problems persist as a result of the belief that smaller dogs cannot be competitive in the Standard ring: Some breeders place specimens weighing between 12 pounds and 15 pounds in pet homes regardless of quality, effectively removing them from the gene pool of an already rare breed. Others have kept the 12- to 14-pound dogs in the Toy ring. While keeping these dogs in the gene pool is beneficial, it created a new problem: the actual Toys competing in the Toy ring look deceptively small if one is to assume all of the dogs in the Toy ring are the correct size.
With these conflicting views, one can understand why new people to the breed and aspiring judges pursuing mentoring opportunities may end up more confused than when they started.

From Breed Origins to the Late 1800s
The Manchester Terrier is often cited by breed historians as the closest living direct descendant of the Old English Terrier. This was a broad type of terrier originating in the United Kingdom for which written references can arguably be found as far back as the 1500s. These early dogs came in a variety of sizes, colors, and coat types, from which a number of today’s terrier breeds descend, including Welsh, Lakeland, Border, and Bull Terriers.
By the early 19th century, Manchester Terriers had become known for their varied talents and abilities, with a range of sizes to suit each purpose. Their role beside humankind included the utilitarian – rat catching, controlling vermin on farms, and coursing small game – and the long-outlawed bloodsport of rat baiting. In the rat pits, dogs were given a handicap based on their weight, with smaller dogs becoming prized for their advantage – they were matched against fewer rats. The black and tan “Tiny”, at 5 ½ pounds, is the most famous rat killer in breed history, killing 200 rats in less than an hour.
Developing the Breed Standard
In England, there was no mention of “varieties” in an official capacity when The Black and Tan Terrier Club was formed in 1884, just 10 years after the formation of The Kennel Club itself. The first Breed Standard described a breed that came in three sizes: “Toy (up to 7 lbs), Medium (up to 14 lbs) and Large (up to 22 lbs).”Notably, there was no distinction in the weight for dogs versus bitches in these ranges, something that holds true in the AKC Breed Standard today.
In 1885, just one year after the formation of the AKC, the first Black and Tan Terrier was recorded in the AKC Stud Book. In 1889, the AKC Gazette published the Breed Standard written by the Black and Tan Terrier Club in England, which became the US Standard as there was no organized AKC parent club representation for the breed at the time.
An excerpt from an 1885 Q&A column in US magazine The Bazaar byKennel Editor Hugh Dalziel answers a question about how large a reader’s Black and Tan Terrier puppy may grow. “We cannot tell you the size yours will grow to, as these dogs vary from a few pounds weight up to 30 lb.”Dalziel was author of several books about British dog breeds, and his reply provides further historical evidence of the range in size recognized in the Black and Tan Terrier.

Breed Development and Early 20th Century
In 1903, The Kennel Club in England began referring to the smaller specimens as Black and Tan Terriers (Miniature).
In the 1912 AKC Gazette it was announced that AKC had recognized the Manchester Terrier Club of America. By then, the AKC was referring to the smaller specimens as Toy Black and Tan Terriers and the larger as Manchester Terriers.
Just a few years later, the 1917 AKC Gazette published a ruling from the AKC Stud Book Committee declaring the Manchester Terrier and the Toy Black and Tan Terrier to be “distinct varieties of the same breed.” The committee further provided guidance on how to register dogs of inter-variety breeding, since the varieties were still registered separately at the time, though inter-breeding was permitted. Guidance was also provided on exhibition based on weight: “Any Manchester Terrier over one (1) year old of registered Manchester parents under 12 lbs in weight, may be shown as a Toy Black and Tan. Any Terrier having one parent Toy Black and Tan and one parent Manchester, must be shown as a Toy Terrier if under 12 lbs, and as a Manchester Terrier if over 12 pounds.”
That same year, breeder G. “Nellie” Campbell Schmidt shared the ruling in The Dog Fancier and offered this perspective: “… all breeders who are producing show stock use breeding stock weighing from three to 12 pounds, this statement can be verified by a close study of the parentage past and present, of show dogs; with few exceptions they trace to Manchester Terriers. My own little bitch, Champion Cambell’s May Bee, who won her championship under five pounds, was the grand-daughter of a fifteen pound bitch, being in the pedigree of almost every western winner for the past ten years.”
In England, following World War I, the larger size was nearly extinct, so perhaps that is why they were not officially renamed as the Manchester Terrier until the mid-1920s when their population was starting to rally. Despite the separation, the Miniatures and Manchester Terriers continued to have identical Breed Standards with the exception of weight and height. A 1931 breed profile that appeared in The Guardian by an author identified as J.B. stated, “From the large variety of Manchester terriers the miniature one has been bred down, and except in the matter of size, he resembles his larger brother in every way.”
In a 1933 announcement from the AKC, they were officially renamed by the AKC Board to what we know them as today; the Standard Manchester Terrier and Toy Manchester Terrier. In that same announcement, the ability to inter-variety breed was reaffirmed.
Throughout the early 1900s, numerous articles in the media highlight the debate among fanciers about whether the two varieties should be separate breeds, and each time the AKC reaffirmed that the Toy had always been and will continue to be, “a diminutive version of the standard” (terminology that remains in the AKC Breed Standard today).
In the late 1800s and early 1900s, it became fashionable in some circles to breed the Toy variety as small as possible. The result was specimens as small as two and three pounds, with a resulting loss of vigor and breed type. Perhaps due to the poor condition of the Toy variety, or because the country of origin had already split the varieties into separate breeds, in 1937, The Manchester Terrier Club requested that AKC discontinue the practice of registering inter-variety breedings. It should be noted that the Toy Manchester Terrier at the time was without organized representation, as the parent club was not formed until 1938. The AKC refused to change its policy regarding inter-variety breeding and, in their response, wrote:
“The committee feel that cross-breeding of the two can produce only Manchester Terriers and that, therefore, they are entitled to certification by the American Kennel Club as pure-bred. They cannot be considered mongrels. Breeders of Toy have found it necessary and desirable from time to time to introduce the blood of the Standard size dogs into their strains. Breeders of the Standard size need not breed their dogs to Miniatures unless they wish to. The Manchester Terrier Club which functions for the Standard size Manchester and is not interested in the Toy Manchester, may, if it wishes, endeavor to discourage the cross-breeding by pleading its members not to breed their dogs to Toys, but there seems no reason for the American Kennel Club to refuse the result of such cross-breeding registration in the Stud Book.”
1950s to Modern Era
World War II resulted in another near extinction for the Manchester Terrier in Europe, and The Kennel Club in England once again permitted inter-breeding with the Miniatures into the 1950s.
Around this same time, The Kennel Club in England recognized revised Breed Standards. It renamed the Miniatures to English Toy Terriers (Black and Tan) as they are known today, particularly in the UK and Europe. While inter-breeding was eventually disallowed in the UK, this restriction of the gene pools has been circumvented by importing dogs from North America where inter-variety breeding has been continuously allowed.
In the U.S., where the Standard Manchester never really enjoyed high numbers, the larger variety had declined to the point where the parent club had dissolved. To that end, the varieties were formally re-combined and placed under the umbrella of one breed club in 1959. Prior to the American Toy Manchester Terrier Club’s (ATMTC) 1958 annual meeting, for which the members were due to vote on whether to combine the breed clubs, a persuasive letter was penned by the ATMTC leadership and sent to the membership. It stated in part:
“This feature is we believe invaluable to Toy Man. Breeders. It will give more latitude in improving the Toy by protecting the usefulness of good dogs who are three or four pounds too big….The problem of oversized Toys has long plagued our Club and its breeders. That problem has long been discussed at our annual and other meetings. This is a grand opportunity to settle this matter once and for all.”
It’s important to recognize that the restriction on exhibiting “oversized Toys” was self-imposed among American breeders. The term “oversized Toys” is, in fact, a misnomer, though still heard around the ring and in breed circles today.
The Breed Standard clearly states that once a dog exceeds 12 pounds, it must be exhibited in the Standard variety. And while the recombination of the varieties did take some persuading, the vote did pass. The resulting increase of inter-variety breeding successfully restored breed type and genetic diversity in the breed as a whole.
Clipping from the June 1963 AKC Gazette showing the breed column authored by Mrs. John P. Knox, Jr.
Just a few years later, in the June 1963 breed column published in the AKC Gazette and penned by Mrs. John P. Knox, Jr., the newly named American Manchester Terrier Club celebrated the first awarding of Best of Breed for the Manchester Terrier in AKC history. The author highlighted that a Standard was awarded BOB and a Toy was awarded Best of Opposite Sex, and concluded that, “doing [so] at this show, our show of shows, must prove beyond a shadow of a possible doubt to sceptics here and abroad, that we do indeed consider our Manchester Terriers, regardless of Variety, to be one and the very same breed!”
The 1959 combining of varieties is often cited by breed fanciers today as the point at which the Toy and Standard debate began, but as the club correspondence shows, club leadership had hoped it would put this debate to rest. If only!
Finally, our historical trek concludes with the aforementioned letter distributed by the AMTC in December 2023. Directed to AKC judges approved to judge the breed, the letter among other things, pleaded with judges to weigh larger exhibits to ensure that they were not over the maximum weight as defined for each variety, and providing all exhibits were within the allowable range (12 pounds and Under for Toys, Over 12 and not exceeding 22 for Standards) give equal consideration to all exhibits regardless of weight. That letter states:
“With regards to size, our standard states that “The Toy variety shall not exceed 12 pounds,” and “The Standard variety shall be over 12 pounds and not exceeding 22 lbs.” Please note, there is no preference for size described within the weight limit. Historically, the breed was regarded for its versatility, which is partly due to the range of size found within the varieties. Judges should not disregard smaller specimens in either variety based on size alone.”[emphasis in original]
The Debate Continues
We have now examined numerous primary sources demonstrating that historically, the two varieties have been treated as one, both in breeding and exhibition – and its staunchest supporters have been arguing about it for the entire time as well!
Today’s breeders seem to fall into two camps; those who believe it is a cardinal sin to inter-variety breed, affecting the purity of their favored variety, and those who believe inter-variety breeding is beneficial to the genetic diversity and conformation of the breed as a whole.
The AKC’s position has been consistent for more than 100 years, and the AMTC has been steadfast since its founding. The AKC Breed Standard describing both sizes of Manchester Terrier, has been almost identical since they were first written down more than 140 years ago.
As shown in the accompanying artwork, breed type, regardless of size, remained consistent 150 years ago. It is long past time to put the argument to rest.
It is important for judges, breeders, and exhibitors to remember that differences in size are a defining feature of the breed, not a flaw. Similarly, there’s nothing wrong with breeders having a preference for one size variety over another, as long as these preferences don’t come at the expense of the breed. It is vital that we educate new fanciers and aspiring judges in a way that is accurate, consistent, and derived from historical facts. The continuation of what is arguably one of the oldest terrier breeds depends on our ability to be unified in protecting its best interests and safeguarding it for future generations to discover.
