The Breed Archive for Chihuahuas is exclusively for provably pure-bred chihuahuas registered with internationally recognised registries of purebred chihuahuas. To keep our archive clear and reliable we cannot allow dogs without papers or mixes (except for ancient ancestors of the breed).
For most of the world this means that the dogs must be registered with their national registry, ie 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).
Some countries employ a different approach, breeders not being 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 registerable, every dog in the litter is registerable. Even if a breeder, or the new owner choose not to register a particular dog, the dog in question remains a purebred chihuahua and is therefore eligible for inclusion on the Breed Archive.
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.

Copyright is the right of the creator of an original work. The word copyright (a right to copy) indicates what this right is all about. Copyright gives the creator of a work for a certain time period an exclusive right with some limitations to decide of the work. Others must respect this right. Copyright is granted to the creator automatically. When the time period expires the work is said to enter the public domain. It is available for anyone to use for any purpose.
A work needs to have some creative nature in order to have copyright protection. A creative work can be a written work or an artistic work. Copyright is given for example to a poem, an article, a book, a composition, a painting or a photograph.
The exclusive right of the creator means that the copyright holder has the right to decide of the work exclusively. He/she can decide for example of the publication, distribution and adaptation of the work. He/she can also have some moral rights for his/her work, e.g. the right to be granted for it. This exclusive right has some limitations (e.g. private use). The copyright holder has the right to sell or assign his/her right to someone else. This means that a copyright or aspects of it may be assigned or transferred from one party to another.
The copyright of a photograph belongs to the photographer. The time of expiring of the copyright can vary but in some cases the copyright expires only 70 years after the death of the photographer.
The photographer can sell his/her copyright or parts of it to someone else. In many cases the photographer only sells a photograph without selling the copyright. In these cases the photographer has still the copyright but he/she sells the photograph for private use or some other agreed use. The photographer can also grant a license to use the photograph. In some countries personality rights can restrict the use of photographs. This concerns e.g. photographs of individuals.

No. Copyright does not protect
information itself. Information about animals is not copyrighted,
but is public information accessible via national animal
registries, catalogues, databases, pedigrees or other paperwork.
Therefore anyone can add an animal or edit the information about a
animal including the name, titles, date of birth, breeder etc. This
information is usually publicly available and it is not
copyrighted nor is it private information. The owner or the
breeder of an animal does not have the exclusive right to decide
whether the information of his/her animal can be added to a
