Abstract
Obesity is a common nutritional problem in dogs. It can lead to decreased longevity and to development of secondary diseases. In the presente study, 12 obese dogs have undergone caloric restriction for weight loss for four months. Physical, nutritional and laboratory parameters of all animals were evaluated. There was a significant decrease in body weight, fat percentagem and morphometric measurements. Hypercholesterolemia and hypertriglyceridemia were present at the onset of treatment, but a significant decrease in total cholesterol and LDL fraction were observed at the end of the trial. We also noticed a considerable increase in final serum urea levels, with no concomitant increase in creatinine levels. Other laboratory parameters showed no significant variations during the trial. Based on these results, one can conclude that there was a significant decrease in body weight in animals subjected to caloric retriction, with maintenance of weekly weight in animals subjeted to caloric restriction, with maintenance of weekly weight loss between 1-2%, and that they remained healthy after the experimental period.
