Disorder-level severity scoring for eight common disorders of UK dogs with evidence for breed-related status, including individual severity sub-scores and summative overall severity score

Disorder assessed	Categorical disorder-level severity metric sub-scores based on case group data over study year (categories represented by sub-scores 0–3 [see Table 5])							Overall disorder-level severity score
	Severity metric 1: Disorder as reason presented for veterinary care during study year	Severity metric 2: Frequency of disorder-related primary care clinic visits during study year	Severity metric 3: Chronicity of disorder-related analgesia (including AI) therapy during study year	Severity metric 4: Range of other (non-analgesic/AI) therapeutic groups used for disorder treatment/management in study year	Severity metric 5: Surgical depth of any disorder-related procedures performed under GA/sedation during study year	Severity metric 6: Disorder-related overnight primary-care hospitalisations during study year	Severity metric 7: Disorder-related referral during study year

Sub-score allocation is at the disorder-level, based on application of the severity metric scoring criteria (see Table 5) to group data obtained via structured review of electronic health records from 250 affected dogs per disorder during 2013
