Serum lipid and lipoprotein concentrations in 10 obese and 16 control dogs were examined. The serum triglyceride (TG) concentration in obese dogs was significantly higher than in control dogs. The serum concentrations of TG and phospholipid (PL) in beta lipoprotein and PL in pre-beta lipoprotein were significantly higher in obese dogs, while the serum PL concentration in alphal lipoprotein was significantly lower in obese animals. In the serum total cholesterol concentration in obese dogs, a higher tendency for beta and pre-beta lipoproteins and lower tendency for alpha1 lipoprotein were observed. These abnormal lipoprotein profiles were similar to those in diabetes mellitus in men and acute pancreatitis in dogs.
