Animal entries

The Breed Archive for English Toy Terriers (ETT), Toy Manchester Terriers (TMT), Manchester Terriers (MT UK/FCI) and Standard Manchester Terriers (SMT) is exclusively for provably pure-bred aforementioned terriers, registered with internationally recognized registries of purebred dogs. To keep our archive clear and reliable we cannot allow mixed breed dogs (except for ancient ancestors of the breed).

For most of the world this means that the dogs must be registered with their national registry, i.e. with participating members of the FCI (Fédération Cynologique Internationale). Exceptions to this are the United Kingdom and its territories, the United States of America, and Canada. In the UK, the Kennel Club (KC) is the only acceptable registry for purebred dogs. Dogs bred in the Republic of Ireland, and several of the Channel Islands may be registered with the authorities in those locations that are linked by agreement with either the Kennel Club or the FCI. Canadian dogs must be registered with the Canadian Kennel Club (CKC), American dogs with the American Kennel Club (AKC).

In some countries breeders are not required to register the full litter or each individual dog. In accordance with the American Kennel Club’s ''eligible for registration'' requirement, we take the position that if any one dog in a litter is registrable, every dog in the litter is registrable. Even if a breeder, or the new owner choose not to register a particular dog, the dog in question remains a purebred dog and is therefore eligible for inclusion on the Breed Archive.

For registration purposes, it is important to designate the correct breed or variety in the field marked "variety". In North America (Canada and the USA), the variety chosen for purposes of this pedigree database should reflect the actual or anticipated adult weight of the dog in accordance with the weights described for Toy and Standard Manchester Terrier varieties in the applicable standard of perfection. In the rest of the world, users should select English Toy Terrier (ETT) or Manchester Terrier (MT UK/FCI) as appropriate.

Pedigree analysis

We offer an extensive pedigree analysis page for each animal stored in the TBA database. This analysis contains the inbreeding coefficient (Wright's formula), ancestor loss, the partial inbreeding coefficient, the blood quota and more.

Please note: The pedigree analysis is based on the information in the database and is only accurate to that extent.

You can find a link to the pedigree analysis page on each animal's detail page and on the testmating page.

The pedigree analysis page calculates the inbreeding coefficient, ancestor loss, blood quota and the partical inbreeding coefficient (only up to the 5th generation) for a particular animal or testmating.

For details on the calculations study the tooltip information on the pedigree analysis page.
