BACKGROUND: In recent years, disorder in lipid metabolism has been increased markedly in companion animal’s population. Hyperlipidemia is a common sign of obesity in dogs, which is characterized by hypercholesterolemia or hypertriglycemia. OBJECTIVES:  The purpose of the present survey is to determine the effect of obesity on blood lipid profile changes (including triglyceride, total cholesterol, HDL-C and LDL-C) and comparing the decisive indicators of obesity in dogs in Ahvaz district. METHODS: Three groups of thirty dogs  referred to Veterinary Hospital of Ahvaz were studied between  2012-2014. The dogs in group A (control), had good body condition score (BCS= 4 to 5). The dogs were all thin (BCS= 1 to 3) in group B, and all obese in group C (BCS= 6 to 9). All of the studied dogs were selected from small breeds (Terrier, Spitz, Pekingese and Shih Tzu), of both sexes and ranging from 1 to 7 years old. Fasting blood samples were collected from all dogs and lipid profiles including serum triglycerides, total cholesterol, HDL and LDL were measured using commercial kits. RESULTS: Hyperlipidemia was confirmed in dogs of group A (normal) in 4 cases (13.33%), group B (thin) one case (3.33%), and group C (obese) in 19 cases (63.33%). Data analysis showed that there was a significant difference between group C (224.83±74.34) with groups A (149±39.66) and B (131.80±24.37) for triglyceride level (p<0.001), as well  a significant difference was seen between group C (229.40±60.36) with groups A (178.80±50.17) and B (151.47±23.45) and between group A with B for cholesterol level (p<0.05). The difference was significant for LDL-C between group C (67.10±22.83) with groups A (47.97±13.01) and B (43.07±13.08) (p<0.001), but there was no difference between various groups for HDL-C (p>0.05). The effects of age, gender and breed on the measured values did not show a significant difference between three groups (p>0.05). CONCLUSIONS: The present survey showed that there was a correlation between obesity and hyperlipidemia in dogs. Determination of body condition score (BCS) can be as a predictive agent in characterization of lipid profile status. Modification of diet and weight loss is necessary in obese dogs.
