The role of domestic dogs in the long-distance spread of bluetongue virus (BTV) remains unproven. It is currently known that dogs are capable of being infected with BTV, can mount an antibody response to the virus and in some cases die showing severe clinical signs of disease. Infection of dogs is currently thought to be by oral ingestion of infected meat or meat products rather than through vector feeding. In this study we show that a high percentage of domestic dogs in Morocco (21%) were seropositive for BTV and, as these dogs were fed tinned commercial food only, and had no access to other meat products, the most likely source of infection was through Culicoides midges. This finding increases the chances of dogs being infected with BTV during an outbreak but their role in the onward transmission of BTV remains unproven.
家犬在蓝舌病病毒（BTV）的远距离传播中的作用尚未得到证实。目前已知，家犬能够感染 BTV，能够对病毒产生抗体反应，在某些情况下，会出现严重的临床疾病症状并死亡。目前认为，犬类感染是通过口服感染的肉类或肉类产品而不是通过媒介物传播。在本研究中，我们表明摩洛哥的家养犬中有很高的比例（21%）对 BTV 呈血清阳性，而且由于这些犬只仅喂食罐装商业食品，并且无法接触其他肉类产品，因此最有可能的感染源是通过虻属媒介物。这一发现增加了犬类在疫情期间感染 BTV 的可能性，但它们在 BTV 的进一步传播中的作用仍未得到证实。
