Dog Age and Breeds Associated with High Plasma Cholesterol and Triglyceride Concentrations

Abstract

The objectives of this study were to set specific dog breed and sex standards for total cholesterol (T-Cho) and total triglyceride (T-TG) concentrations in dogs and to quantify the associations between dog age and concentrations of both lipids for different breeds. Increased age was associated with higher T-Cho and T-TG concentrations in all five breed groups (P<0.05); T-Cho concentrations increased by 62.5 mg/dL between 9 and 16 years of age, and T-TG concentrations increased by 4.8 mg/dL per year of age (P<0.05). Miniature Schnauzers had the highest T-Cho concentrations of the studied breeds, while Miniature Dachshunds had the lowest concentrations (P<0.05). Veterinarians should consider dog age and breed when they use the lipid concentrations for diagnostic purposes.
