The rates of dog obesity are increasing and a greater understanding of feeding patterns is required to combat the problem. This study examined relationships between dietary patterns and caloric intake, and nutrient content of foods fed as it relates to obesity in dogs in the United States. Sixty-one owners and their dogs were enrolled, and lifestyle surveys, food frequencies, and 3-day food records were collected. Significant differences in overall kcal intake per kilogram of body weight were found (p< 0.04). Crude fibre in dog food was positively associated with protein and negatively associated with fat regardless of the dog's weight (p< 0.001). Lean dogs received significantly more crude fibre in relation to overweight dogs regardless of the number of treats they received (p< 0.01), and their diets had greater micronutrient densities (p< 0.03) suggesting that high fibre influences body condition. Additionally, owners who ate nutrient-rich, calorie-poor diets had normal weight dogs, and owners that fed more table scraps had overweight dogs. Regardless of body condition, 59% of dogs received table scraps, which constituted 21% of daily caloric intake. The nutrient density of scraps fed was variable and did not meet National Research Council's recommendations for micronutrient adequacy.
狗肥胖的比率正在上升，因此需要更好地了解喂养模式，以解决这一问题。本研究在美国对与狗肥胖有关的饮食模式、热量摄入和食物营养成分之间的关系进行了研究。共纳入 61 名狗主人及其宠物，收集了生活方式调查、食物频率和 3 天食物记录。发现狗的总体每公斤体重的热量摄入存在显著差异（p<0.04）。无论狗的体重如何，狗食中的粗纤维都与蛋白质呈正相关，与脂肪呈负相关（p<0.001）。与超重狗相比，瘦狗无论吃多少零食，摄入的粗纤维都明显更多（p<0.01），并且它们的饮食具有更高的微量营养素密度（p<0.03），这表明高纤维会影响身体状况。此外，饮食中营养丰富、热量低的狗主人养的狗体重正常，而喂更多残羹剩饭的狗主人养的狗超重。无论身体状况如何，59%的狗都吃残羹剩饭，这些食物占每日热量摄入的 21%。残羹剩饭的营养密度各不相同，不符合国家研究委员会对微量营养素充足性的建议。
