Tungiasis is a public health problem in endemic resource-poor communities, where dogs are important reservoirs of Tunga spp., contributing significantly to the process of transmission of this zoonosis. In order to optimize the diagnosis of canine tungiasis, macroscopic morphological characteristics and clinical signs of the lesions were investigated, based on the inspection of 40 dogs infested by T. penetrans from an endemic rural community in northeastern Brazil. Of the 1546 lesions found in these dogs, including all stages of development of the parasite, 89.1% (1378) were located on the paw pads. Dogs aged up to 5 years had the greatest number of lesions. Dark pigmentation and hyperkeratosis of the paw pads made it difficult to identify the lesions. Among all the clinical signs observed were hyperemia (38; 95%), pain (32; 80%), fissure (11; 27.5%), onychogryphosis (29; 72.5%), cluster of lesions (26; 65%), hyperkeratosis (25; 62.5%), lameness (15; 37.5%), and fissure (11; 27.5%). Ectopic lesions were found especially in the nipples (64; 4.1%) and abdomen (51; 3.3%). The maximum diameter of the stage III neosomes was 6 mm. Dogs with a higher number of lesions had a higher degree of hyperkeratosis. Age over 1 year was associated with a higher rate of dispersion of the parasite in the environment (p = 0.04). The identification of the initial stages of tungiasis can guarantee a more effective control of the disease in dogs, which will mainly depend on the treatment of adult animals and the application of continuous preventive actions based on One Health in these communities.

潜蚤病是地方性资源贫乏的社区，狗是重要的水库是一个公共卫生问题蚤属。，极大地促进了这种人畜共患病的传播过程。为优化犬病的诊断，在对40例被T. penetrans感染的狗进行检查的基础上，研究了其宏观形态学特征和病变的临床体征来自巴西东北部的一个地方性农村社区。在这些犬中发现的1546个病变中，包括寄生虫的所有发育阶段，其中89.1％（1378）位于脚掌上。年龄在5岁以下的狗的病变数量最多。脚掌的深色色素沉着和过度角化使其难以识别病变。在观察到的所有临床体征中，有充血（38; 95％），疼痛（32; 80％），裂痕（11; 27.5％），甲癣（29; 72.5％），病灶簇（26; 65％），角化过度（25; 62.5％），la行（15; 37.5％）和裂缝（11; 27.5％）。特别是在乳头（64； 4.1％）和腹部（51； 3.3％）中发现了异位病变。III期新体的最大直径为6 mm。皮损数量较多的狗角化过度程度较高。p  = 0.04）。耳gia虫病的初始阶段的确定可以确保更有效地控制狗的疾病，这主要取决于成年动物的治疗以及在这些社区中基于One Health的持续预防措施的应用。
