DNA Testing
Every Silken must be DNA-tested prior to breeding. If the breeder disregards this DNA testing requirement the ISWS Registrar will not enter any of the offspring into the ISWS Registry until the breeder complies with the regulation.
DNA testing for ISWS is done through UC Davis' Veterinary Genetics Lab (VGL). Buccal (cheek) swabs are submitted to the lab through the ISWS Registrar and DNA is extracted from the acquired sample. A computer program then compares the DNA profile to that of the parents listed on the form and a parentage analyst reviews the results and produces a final report. If a listed parent or parents are excluded, then an additional analysis is performed which may include the use of additional DNA markers.
The fee for testing individual dogs is $38. You may also test a litter (minimum of 4 puppies) at a reduced cost of $33 per each individual.
