Classification of disorders:

• "Genetic" - disorders that are inherited diseases with no link to conformation (= "D" in Summers et al)
  
• "Total" - disorders resulting from selection for a conformation trait, or exacerbated by a conformation trait (= "C + CD" in Summers et al), plus "genetic" (i.e., C + CD + D).

Genetic Illness Severity Index for Dogs:

• Based on evaluation of 4 aspects of each disorder (prognosis, treatment, complications, and behavior), with severity for each ranging from 0 to 4. Total score for a disorder can range from 0 (least severe) to 16 (most severe).  Cumulative GISID score is the sum of all of the total scores for each disorder.  (pdf)
