Canine obesity is now the number one health concern in dogs worldwide. Regular physical activity can improve health, and owners are advised to exercise their dogs on a regular basis. However, limited information exists about associations between overweight status of dogs and walking activity. An online survey was conducted between June and August in 2014, coinciding with the broadcast of a national UK television programme, exploring dog behaviour. Information gathered included signalment, overweight status, and owner-reported information on duration and frequency of dog walking. The University of Liverpool Ethics Committee approved the project, and owners consented to data use. Simple and multiple logistic regression analyses were used to determine associations between overweight status and dog walking activity. Data were available from 11 154 adult dogs, and 1801 (16·1 %) of these were reported as overweight by their owners. Dogs reported to be overweight dogs were more likely to be neutered ( < 0·0001) and older ( < 0·0001). Various breeds were over-represented including beagle, Cavalier King Charles spaniel, golden retriever, Labrador retriever and pug ( < 0·0001 for all). Both frequency and duration of walking were negatively associated with overweight status ( < 0·0001 for both). On multiple regression analysis, duration and frequency were independently and negatively associated with the odds of being overweight, along with a range of other factors including age, neuter status and breed. This study has identified associations between overweight status and exercise. In the future, studies should determine the reason for this association, and whether changes in walking activity can influence weight status.
犬类肥胖现已成为全球犬类首要的健康问题。规律的体育活动有助于改善健康状况，建议犬主定期带狗狗锻炼。然而，关于犬类超重状态与散步活动之间的关联，目前所知信息有限。2014年6月至8月期间开展了一项在线调查，该时段恰逢英国一档探讨犬类行为的全国性电视节目播出。收集到的信息包括犬只的特征、超重状态，以及犬主报告的遛狗时长和频率。利物浦大学伦理委员会批准了该项目，犬主也同意使用相关数据。采用简单和多元逻辑回归分析来确定超重状态与犬类散步活动之间的关联。共有11154只成年犬的数据可供分析，其中1801只（16.1%）被犬主报告为超重。报告为超重的犬只更有可能已绝育（P<0.0001）且年龄较大（P<0.0001）。多种犬种超重比例过高，包括比格犬、查理士王小猎犬、金毛寻回犬、拉布拉多寻回犬和哈巴狗（所有品种P均<0.0001）。散步的频率和时长均与超重状态呈负相关（两者P均<0.0001）。多元回归分析显示，散步时长和频率与超重几率独立且呈负相关，同时还与一系列其他因素有关，包括年龄、绝育状态和品种。本研究确定了超重状态与运动之间的关联。未来，研究应确定这种关联的原因，以及散步活动的变化是否会影响体重状况。
