At a glanceCarrier and affected are condition-specific genetic labels. Their meaning depends on the tested variant, inheritance pattern and laboratory interpretation.WORKING DOG reference library · Added 2026-10-19 · Expert review pendingThis educational guide has not been reviewed by a veterinary professional. Discuss decisions about your dog’s health or diet with your veterinarian.Keep the test name visibleThe UC Davis VGL glossary explains genetic vocabulary, including carrier terminology. A public profile should name the actual test rather than display a general carrier badge. That label without context can mislead readers into assuming a dog is ill, contagious or unsuitable for every activity when none of those conclusions has been established.A reporting exampleImagine a laboratory report identifying one copy of a variant in a specific recessive test. Preserve the laboratory’s exact result and explanatory context rather than applying that interpretation to another condition with a different inheritance pattern. A genotype, a risk statement and an observed clinical diagnosis are different facts; do not substitute one for the others.Avoid automated clinical conclusionsThis reference does not diagnose disease, recommend breeding or predict an individual dog’s future. Ask the laboratory and veterinarian about consequential interpretation and use current, breed-relevant information. For a public record, verify dog identity and permissions and retain the report date. Omit unrelated owner details and explain when the available evidence is only a submitted claim awaiting review.Sources & further readingReferences for this guide.
