Cardigan Welsh Corgi: health-screening sources

Key facts

Hip evaluation

OFA or PennHIP named [source]

PRA evidence

Direct testing or documented ancestry [source]

DM wording

Genetic risk, not certain clinical disease [source]

The Cardigan source is not a Pembroke checklist

The Cardigan Welsh Corgi Club of America’s published statement identifies OFA or PennHIP hip assessment, a PRA genetic test and a DNA test addressing DM risk. It also describes the club’s list of dogs tested for PRA or cleared through documented ancestry. AKC’s breed summary identifies the PRA-rcd3 test specifically. Retaining that form name matters because PRA describes a group of retinal disorders with different tests in different breeds. A certificate saying PRA clear without the actual assay and dog identity leaves an important part of the evidence unspecified.

DM testing estimates a particular inherited risk

UC Davis’s DM guidance explains that the common SOD1 variant has incomplete penetrance in clinically associated breeds, including the Cardigan. Not every dog with two copies develops the disease, and other neurological or orthopaedic conditions can resemble it. A DNA result is therefore not a diagnosis for a dog with difficulty walking. It also cannot state the exact age at which an individual will become ill. Preserve the laboratory’s result wording and variant information for veterinary interpretation rather than changing at risk into will develop disease in a breeder summary.

Ancestry clearance needs its own documentary chain

The club’s reference to PRA status established through parentage is meaningful only when the underlying ancestors, their results and the relationship to the dog are supported. It is a different evidential route from a direct sample tested from that dog. Neither route replaces the hip report or establishes all-round clinical health. Keep direct testing, ancestry-based status and radiographic evaluation in separate fields when comparing a litter’s records. This approach follows the source’s actual categories and makes it possible to discuss the relevant findings with a veterinarian without using the Cardigan’s shared Welsh name as a reason to import another breed’s screening list.
