HTG, hypertriglyceridemia; MN, male neutered; MI, male intact; MU, male unreported reproductive status; FS, female spayed; FI, female intact; FU, female unreported reproductive status; BCS, body condition score (1–5 scale); TG, serum triglyceride concentration; UPC, urine protein-to-creatinine ratio.

Values are mean ± standard deviation for age (years) and cholesterol (mg/dL), median (range) for BCS, TG (mg/dL) and UPC, and count (proportion) for UPC subcategories. Significant differences between dogs with and without HTG within study groups are denoted with

^*P < 0.05.

^aUPC data is only reported for 12/16 dogs in the OSU group with HTG; see the text for explanation.
