Canine Dermatopathology is a comprehensive resource for veterinarians, clinicians, students, and faculties that delves into the dermatological disorders in dogs. As dermatology constitutes a significant portion of daily caseloads in small animal practice, this book emerges as an invaluable tool in providing a logical and sequential approach to tackling the challenges presented by various skin conditions. The canine skin, being the largest organ with multifaceted functions, demands a nuanced understanding. This book recognizes the complexity of dermatological cases and emphasizes the importance of a structured diagnostic approach. In addition to addressing common health problems in pet animals, particularly dogs, the book explores a myriad of aetiologies, including ecto/endoparasitic infestations, contact allergens, physical causes, radiation, infectious causes (bacterial, viral, fungal infections), immunological causes, nutritional/metabolic disorders, and endocrine imbalances. It also emphasizes the prevalence of secondary infections and guides veterinarians in successfully managing dermatological cases. The book highlights the significance of specific tests, such as skin scrapings, fungal and bacterial culture, cytological evaluation, and skin biopsy. Cytology emerges as a highly efficient and valuable examination that facilitates rapid lesion evaluation and guides subsequent diagnostic steps. Histopathology, when coupled with clinical findings, leads to definitive diagnoses, especially in cases involving neoplastic nodules or conditions with poor responses to previous therapy. With a focus on cytology, gross morphology, histopathology, and immunohistochemistry, the book equips veterinarians with the knowledge needed for accurate and early diagnosis and treatment of various skin conditions in dogs. It serves as both a ready reckoner and an educational tool for the readers.
