Plain-English summary
A dog with sarcoptic mange (a skin condition caused by mites) was examined using a special tool called entodermoscopy after a skin scraping confirmed the diagnosis. This technique allowed the vet to see specific features of the mites, such as their unique shapes and the tunnels they create in the skin. The findings helped confirm the presence of the mites quickly and without invasive procedures. Using this method, the vet could effectively diagnose the condition and plan appropriate treatment for the dog.

Abstract
BACKGROUND: Diagnosing sarcoptic mange in dogs can be challenging because the clinical signs overlap with those of other pruritic conditions. Entodermoscopy has emerged as a promising technique for the rapid confirmation of suspected scabies mite infestation. OBJECTIVE: To describe the dermoscopic features of sarcoptic mange in a dog. ANIMALS: A dog with sarcoptic mange was examined via dermoscopy after skin scraping confirmation. RESULTS: Distinctive dermoscopic features included: the mite-gallery unit (MGU) and specific mite structures, such as characteristic 'Δ'-shaped gnathosomes, eggs and burrows. Stercoraceous bullets, wake signs and grey-edged line signs also were observed. Polarised and non-polarised light exhibited distinct diagnostic capabilities. Digitally enhanced dermoscopy provided additional details. CONCLUSIONS AND CLINICAL RELEVANCE: The MGU describes the anatomical and functional aspects of scabies mites as epidermal parasites and qualifies dermoscopy as a non-invasive diagnostic tool.
