Dog owners are greatly concerned about tick infestations in their pets. The prevalence and dispersion of ticks and their disease-causing microorganisms have been limited from the viewpoint of dog owners in Vietnam. This study investigated the presence of tick infestation and the pathogens associated with it in canines that were brought to veterinary hospitals in Vietnam. In the survey, 1,423 dogs participated from February to October 2022. Molecular and morphological methods were utilized to identify ticks and the associated pathogens. In addition,risk variables linked to tick infestation were documented and analyzed using statistical methods. The total exposure to the brown dog tick () was 29.01%. Nam Dinh has the highest tick prevalence among the research areas. Tick infestation reached its highest point between June and September in the northern region of the country, with distinct seasons showing a strong correlation with tick infestation in dogs. Out of 177 tick pools examined, 146(82.49%) tested positive for at least one infection. spp. (78.53%) was the most common, followed by spp. (37.29%), (5.08%), , and (2.82%). In the current study, there was a statistically significant link between tick infestation and characteristics such as age, breed, body size, lifestyle, and bathing frequency. Understanding the seasonal behavior of vector ticks is crucial for identifying individuals or animals susceptible to tick-borne diseases. Studying the distribution of ticks and their ability to carry and disseminate zoonotic germs in specific places could assist veterinarians and policymakers in implementing effective strategies to manage zoonotic infections.
狗主人非常担心宠物身上的蜱虫感染问题。从越南狗主人的角度来看，蜱虫及其致病微生物的流行和分布情况一直受到限制。本研究调查了越南送到兽医医院的犬类身上蜱虫感染的情况以及与之相关的病原体。在这项调查中，2022年2月至10月期间有1423只狗参与。采用分子和形态学方法来鉴定蜱虫及其相关病原体。此外，记录并使用统计方法分析了与蜱虫感染相关的风险变量。棕狗蜱（）的总感染率为29.01%。在研究区域中，南定的蜱虫感染率最高。该国北部地区的蜱虫感染在6月至9月达到最高点，不同季节与犬类的蜱虫感染呈现出强烈的相关性。在检测的177个蜱虫样本池中，146个（82.49%）至少有一种感染检测呈阳性。犬埃立克体属（78.53%）最为常见，其次是伯氏疏螺旋体（37.29%）、嗜吞噬细胞无形体（5.08%）、钩端螺旋体和巴尔通体（2.82%）。在当前研究中，蜱虫感染与年龄、品种、体型、生活方式和洗澡频率等特征之间存在统计学上的显著关联。了解媒介蜱虫的季节性行为对于识别易感染蜱传疾病的个体或动物至关重要。研究蜱虫在特定地点的分布及其携带和传播人畜共患病原体的能力，有助于兽医和政策制定者实施有效的策略来管理人畜共患感染。
