This survey aimed to investigate and compare diet type and supplement use between dogs (Canis lupus familiaris, L.) with cancer and a population of owner‐reported healthy dogs and to assess the sources of information dog owners consult. Respondents were mainly from English‐speaking countries. Dogs were considered healthy (N = 213) if owners reported them to be in good health. Dogs were included in the cancer group (N = 132) if the owner reported that their dog had been diagnosed with cancer. An online survey was distributed to clients presenting to a tertiary oncology service, clients presenting to a local primary care veterinary practice, and through social media. Owners of dogs with cancer spent more time researching pet health (P < .001), pet nutrition (P < .01) and nutritional supplements (P < .001) than owners of healthy dogs. While veterinarians were most commonly reported to be an information source for both groups, owners of healthy dogs more likely consulted pet stores and owners of dogs with cancer tended more to social media groups and blogs. Healthy dogs were more likely fed commercial dry food (P < .001), whereas homemade cooked (P < .001) and raw diets (P < .05) were more prevalent among dogs with cancer. Supplement use, especially cannabidiol products, mushroom extracts or turmeric/curcumin, was also more common for this group (P < .001). Alternative diets and supplements were more popular among owners of dogs with cancer compared to owners of healthy dogs. These findings highlight the need for nutritional counselling and education of pet owners regarding nutrition‐related topics, especially when their dog is diagnosed with cancer.

与健康狗相比，非常规饮食和营养补充剂在患有癌症的狗中更为常见：一项对 345 名狗主人的在线全球调查。

该调查旨在调查和比较患有癌症的狗（Canis lupusfamiliais，L.）与主人报告的健康狗群之间的饮食类型和补充剂使用情况，并评估狗主人咨询的信息来源。受访者主要来自英语国家。如果主人报告它们身体健康，则认为狗是健康的（N = 213）。如果主人报告他们的狗被诊断出患有癌症，则将狗包括在癌症组中（N = 132）。在线调查被分发给在三级肿瘤服务机构就诊的客户、在当地初级保健兽医诊所就诊的客户，以及通过社交媒体。患有癌症的狗的主人花更多时间研究宠物健康 ( P < .001)、宠物营养 ( P< .01) 和营养补充剂 ( P < .001) 比健康狗的主人。虽然兽医最常被认为是这两个群体的信息来源，但健康狗的主人更有可能咨询宠物商店，而患有癌症的狗的主人更倾向于社交媒体团体和博客。健康的狗更有可能喂食商业干粮 ( P < .001)，而自制熟食 ( P < .001) 和生食 ( P < .05) 在患癌症的狗中更为普遍。补充剂的使用，尤其是大麻二酚产品、蘑菇提取物或姜黄/姜黄素，在这一群体中也更常见（P< .001）。与健康狗的主人相比，替代饮食和补充剂在患有癌症的狗的主人中更受欢迎。这些发现强调了对宠物主人进行营养相关主题的营养咨询和教育的必要性，尤其是当他们的狗被诊断出患有癌症时。
