Dietary factors (e.g. feeding treats and table scraps) can predispose to obesity in dogs, but it is not known whether they also influence success of weight loss. Therefore, the aim of the present study was to determine which pre-weight-loss factors were associated with outcome of their weight management regimen in dogs. Information from ninety-five dogs attending the Royal Canin Weight Management Clinic, University of Liverpool (Wirral, UK), was reviewed. The effect of different food types (e.g. dry, wet and home-prepared), feeding practices (e.g. method of portion size calculation and number of meals per day) and use of treats was assessed on outcome measures of the weight management regimen. Before weight loss, most owners (sixty-three out of ninety-five, 66 %) fed twice daily, used complete dry food (seventy-two out of ninety-five, 76 %) and calculated portion size either by measuring cup (thirty-six out of ninety-five, 38 %) or by visual estimation (thirty-seven out of ninety-five, 39 %). Feeding treats was common and included purchased treats (forty-one out of ninety-five, 43 %), table scraps (twenty-four out of ninety-five, 25 %), pet food (eighty-three out of ninety-five, 87 %) and human food (eighty-one out of ninety-five, 85 %). The majority of feeding practices did not influence any outcome measure for the weight-loss period (P>0.05 for all). However, metabolisable energy intake during weight loss was significantly higher in dogs fed dry food (P = 0.047) and lower in dogs fed purchased snacks before weight loss (P = 0.036). Thus, most pre-weight-loss factors have limited effect on outcomes of weight loss. The significance of the associations identified between feeding of dried food and purchased treats, and weight-loss energy intake, requires further study.
饮食因素（例如喂零食和餐桌上的残羹剩饭）可能使狗容易肥胖，但目前尚不清楚它们是否也会影响减肥的成功。因此，本研究的目的是确定哪些减肥前的因素与狗的体重管理方案的结果相关。审查了 95 只在利物浦大学（英国 Wirral）皇家宠物营养犬体重管理诊所就诊的狗的信息。评估了不同食物类型（例如干粮、湿粮和自制食物）、喂养方式（例如每餐份量计算方法和每天进餐次数）以及使用零食对体重管理方案的结果指标的影响。在减肥前，大多数主人（95 只中的 63 只，66%）每天喂两次，使用全干粮（95 只中的 72 只，76%），并通过量杯（95 只中的 36 只，38%）或目测（95 只中的 37 只，39%）计算份量。经常喂零食，包括购买的零食（95 只中的 41 只，43%）、餐桌上的残羹剩饭（95 只中的 24 只，25%）、宠物食品（95 只中的 83 只，87%）和人类食品（95 只中的 81 只，85%）。在减肥期间，大多数喂养方式对任何结果指标都没有影响（所有 P>0.05）。然而，喂干粮的狗在减肥期间的代谢能摄入量显著较高（P=0.047），减肥前喂购买的零食的狗的代谢能摄入量较低（P=0.036）。因此，大多数减肥前的因素对减肥结果的影响有限。需要进一步研究确定与喂干食和喂购买的零食以及减肥能量摄入之间的关联的意义。
