Esta dissertação aborda a perspectiva clínica de algumas dermatites parasitárias frequentes
no cão. O diagnóstico é algo difícil devido à semelhança da sintomatologia. Uma anamnese
minuciosa é extremamente útil, nomeadamente no que se refere aos dados sobre a raça, a
idade, o surgimento dos sintomas e sua evolução, e a presença de outros animais
afectados. Existem animais portadores assintomáticos. Nas dermatites contagiosas é fulcral
tratar os ambientes contaminados para eliminar fomites e prevenir recidivas. A sarcoptose, a
queiletielose e as dermatofitoses são zoonoses. Um exame físico completo é relevante para
o diagnóstico. As lesões e a sua distribuição fornecem pistas importantes da etiologia,
auxiliando no estabelecimento de diagnósticos diferenciais. Algumas destas dermatites
como a DAPP e as dermatites por Malassezia spp. têm uma forte componente alérgica. As
dermatofitoses, as dermatites por Malassezia spp. e as demodicoses apresentam factores
predisponentes que devem ser eliminados/controlados. Várias técnicas laboratoriais
dermatológicas podem ser executadas na prática clínica. Os princípios activos usados no
controlo/tratamento e respectivas apresentações comerciais têm acção contra vários
agentes, facilitando e melhorando o seu uso. As necessidades do cliente, a sua condição
económica, a personalidade e o próprio cão influenciam o controlo/tratamento. A educação
do dono aumenta o seu empenho e o sucesso do controlo/tratamento.
ABSTRACT - PARASITIC DERMATITIS IN THE DOG - The clinical perspective of some frequent parasitic dermatitis in the dog is approached by this essay. The diagnosis is quite difficult due to the similarity of clinical signs. A thorough history is extremely helpful, especially data on breed, age, onset of symptoms and their development, and the presence of other affected animals. Asymptomatic carriers do exist. The treatment of contaminated environments is crucial in contagious dermatitis to eliminate fomites and prevent relapses. Sarcoptosis, cheyletiellosis and dermatophytosis are zoonoses. A complete physical examination is very useful for diagnosis. Lesions and their distribution give important clues of etiology, helping the establishment of differential diagnosis. Some of these dermatitis such as FAD and Malassezia spp. dermatitis have a strong alergic component. Dermatophytosis, Malassezia spp. dermatitis and demodicosis present predisposing factors that should be eliminated/controlled. Several dermatologic laboratory techniques can be executed in common clinical practice. The drugs used in control/treatment and their commercial presentations have action against several agents, making them easier and better to use. The client’s needs, economic condition, personality and dog influence control/treatment. The owner’s education increases his compliance and the success of control/treatment.
