Parasitic Dermatitis in Dogs: A Literature Review of Clinical and Diagnostic Aspects and Treatment Approaches

Parasitic dermatitis in dogs is a prevalent issue in veterinary practice, primarily caused by ectoparasites like fleas, lice, and mites. The condition is characterized by non-specific symptoms such as pruritus, erythema, alopecia, and crusts, often complicated by secondary infections. Diagnosis relies on laboratory methods, including microscopic, serological, and molecular techniques. Treatment focuses on insectoacaricidal drugs, particularly isoxazolines and macrocyclic lactones, alongside managing secondary complications and preventive measures. This study highlights the importance of systematic approaches to improve diagnosis, treatment, and prevention in veterinary practice.
