Animal entries

The Breed Archive for American Hairless Terriers is intended for pure-bred dogs registered with internationally recognised registries of purebred dogs. To keep our archive clear and reliable we cannot allow dogs without papers (except for ancient ancestors of the breed). Carefully planned "out-crossings" to the Rat Terrier - the original breed the American Hairless Terrier came from - are allowed to help keep diversity in the gene pool. Once a Rat Terrier is used to breed to an American Hairless Terrier all of the offspring are considered American Hairless Terrier. Each generation a rat terrier is used first is F1, 2nd is F2, 3rd is F3 and the 4th generation is considered full status. When pedigrees are put up it should reflect these on the pedigrees.

In the United States of America, the American Kennel Club (AKC) or the United Kennel Club (UKC) are acceptable registries for the American Hairless Terrier.

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 American Hairless Terrier and is therefore eligible for inclusion on the Breed Archive.

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.
