Taking a cue from large animal production methods, dogs and cats can be rated for complex genetic disease liability through the phenotypic assessment of their close relatives. This is being attempted with hip dysplasia in several dog breeds. However, valid estimated breeding values (EBVs) require the assessment of all close relatives (including all littermates), which is rarely done in dog and cat breeding. The identification of one affected relative or of one normal relative can significantly shift EBVs when full litter assessment would provide a different rating. If EBVs are being offered, they can be used as a tool in addition to direct assessment of the phenotype of the individual and its close relatives.
