Not all labs are equal.
Temperament and health problems are linked to the genetics of the ‘silver’ labs. Interestingly, the few I have met locally all have had either skin issues or been over reactive dogs. Are you willing to put that much time and energy into a dog with health and temperament issues that may not make the grade as a service dog?
Do you research before you make your selection. Genetics are important!
Summary: The Dilute Gene in Labrador Retrievers – Health and Behavioral Problems
by Jack Vanderwyk (August 27, 2014)
The official coat colors recognized for purebred Labrador Retrievers by the American Kennel Club (AKC) and other reputable registries are black, yellow, and chocolate. However, recent decades have witnessed a rise in Labradors with so-called “dilute” colors—“silver,” “charcoal,” and “champagne”—which result from a recessive gene at the D locus (the “d” allele). This dilution gene was not originally present in Labradors, and experts suspect it was introduced through crossbreeding—possibly with the Weimaraner—in the mid-20th century.
The health implications tied to the dilute gene include increased risk for skin and coat conditions like Color Dilution Alopecia (CDA) and Black Hair Follicular Dysplasia (BHFD), which can cause hair loss and skin infections. Other possible issues, reminiscent of those in Weimaraners, involve autoimmune disorders, bleeding problems, kidney disease, and certain behavioral tendencies. Because of these risks and their deviation from breed standards, breed clubs advocate eliminating the dilute gene from the Labrador population.
Genetic testing can now identify carriers and affected dogs. Since 2014, the Orthopedic Foundation for Animals (OFA) maintains a database noting each tested Labrador’s dilution status. Responsible breeders are urged to avoid using dogs carrying the dilute gene in breeding programs.
The issue is international; dilute Labradors bred in the US are now registered in European Kennel Clubs as purebred, allegedly based on unreliable DNA tests. The blog calls for stricter registry standards, stating that any Labrador carrying the d gene should not be considered purebred, to protect the breed’s genetic health and integrity.
