A combined ultracentrifugation and precipitation technique was used to quantify the plasma lipoprotein concentrations of control dogs (n=33) and dogs with diabetes mellitus (n=11), hyper‐adrenocorticism (n=14), hypothyroidism (n=10) and obesity (n=20). In addition, the effect of breed type, age and gender on the lipoprotein phenotype was assessed. Breed type and age were found to have no effect upon cholesterol and lipoprotein concentrations but the high density lipoprotein cholesterol (HDL‐C) concentration was greater in intact females than intact males. Cholesterol concentrations were significantly higher than those of the control group in dogs with diabetes mellitus (P<0·01), hyper‐adrenocorticism (P<0·01) and hypothyroidism (P<0·001). In dogs with diabetes mellitus this was due to increased concentrations of very low density lipoprotein cholesterol (VLDL‐C) (P<0·01) and HDL‐C (P<0·05). The concentrations of low density lipoprotein cholesterol (LDL‐C) (P<0·05) were significantly increased in dogs with hyperadrenocorticism, while in the hypothyroid dogs, VLDL‐C (P<0·05), LDL‐C (P<0·001) and HDL‐C (P<0·05) were significantly higher than the control group. The cholesterol and lipoprotein concentrations in the obese population were not significantly different from control dogs.
