Weight loss in obese dogs: Evaluation of a high-protein, low-carbohydrate diet

Obesity and excess body weight are estimated to affect approximately 25% of dogs receiving veterinary care in Western countries. They are recognized as the most common nutritional diseases in companion animals. Energy restriction both during and after weight loss is the cornerstone to achieve and maintain optimal body condition. An important concern with energy restricted diet, however, is to cover all the requirements for essential nutrients, especially protein. In obese humans and animals, increasing dietary protein during weight loss programs has been shown to maintain lean body mass. The purpose of this study was therefore to assess the effect of a high-protein low-starch weight-reduction diet in the management of canine obesity. In a preliminary study of client-owned dogs nine overweight or obese dogs (8 females and 1 male) with mean ages, body weights and body condition scores (BCS) of 8 y (range 3–10), 30 kg (13.5–48) and 4.6/5 (4.5–5 in a 5-point scale), respectively were recruited. Mean excess body weight was 30% (11–58). History and clinical examination revealed inactivity or lethargy (n = 5), impaired breathing (n = 3) and locomotion problems (n = 2) but all other variables were within normal limits. Treatment consisted of feeding a high-protein, low-starch diet at 40–55% of maintenance energy requirements (MER) for the dog’s estimated optimal body weight until it reached optimum body condition. Dogs were fed twice daily and sessions of exercise of at least 20 min/d were recommended to prevent excess protein catabolism and to minimize losses of fat-free mass (FFM). The time necessary to reach the target weight and a BCS of 3 ranged from 4 to 38 wk (mean ± SEM: 18.3 ± 3.8). The rate of weight loss varied from 0.8 to 3.1% (1.9 ± 0.3) per wk. Weight loss improved or suppressed the inactivity, lethargy, impaired breathing and locomotion problems initially reported by the owners
