Diagnosing the cause of dry crusty patches on dogs involves a thorough examination and diagnostic tests. Veterinarians typically follow a systematic approach to identify the underlying issue.

Infections, such as bacterial or fungal infections, can also cause skin irritation and crusty patches.

By performing diagnostic tests and considering the dog’s history and symptoms, veterinarians can determine the most likely cause and recommend appropriate treatment.
