After physical examination, blood samples were collected and analysed for the biochemical parameters including glucose, cholesterol, alanine aminotransferase, BUN, creatinine, total protein, albumin and globulin. Compared with the established reference range, the results of the study revealed that the normal concentration of biochemical parameters including glucose, BUN, creatinine, albumin and ALT within the normal range. But the concentrations of cholesterol and globulin were gradually increased in obese animals as age advances. Aging had also increased serum total protein and decreased serum albumin gradually. The other parameters were not affected due to aging in obese dogs.enVeterinary ScienceArticle
