In the two years period of research on canine dermatology at College Hospital of College of Veterinary Science Tirupati, 32 dogs with dermatological problems found to have demodicosis. In these cases demodicosis was confirmed by clinical examination, microscopic examination of scrapings and tape impression smears collected from the lesions. In these two different types of Demodex mites were identified based on their habitat and morphology along with micrometry. Micrometry was carried out on 320 mites of two different types of Demodex collected from the all the cases. Demodex canis was identified in skin scrapings with pointed opisthosomal terminal end and mean body length of 211.81± 14.86 μm and mean width of 37.68±0.31 μm. Demodex cornei was noticed in tape impression smears and identification was based on its morphology (stubby farm with a blunt posterior opisthosoma end) and its mean length of 137.15 ± 37.72 μm and mean width of 38.28±0.19 μm. Lengths of total body and opisthosoma of both types of the mites differed statistically significantly but, gnathosoma and podosoma did not differ significantly.

Background and Aim: Canine demodicosis is a skin disease that is a major global health problem in dogs. Ivermectin is a drug of choice for treatment, but it may cause toxicity in dogs carrying multidrug resistance mutation-1 gene mutations. Hence, alternative herbal medicines are used instead of the drug, such as Dipterocarpus alatus oil (YN oil), Rhinacanthus nasutus leaf (WC), and Garcinia mangostana pericarps (MG) extracts. This study aimed to determine the efficacy of D. alatus oil, R. nasutus leaf, and G. mangostana pericarp extracts on canine demodicosis in vivo.
Materials and Methods: Twenty-five mixed-breed dogs with localized demodicosis were examined. Dogs were diagnosed with demodicosis through deep skin scraping and screened with the inclusion criteria. Five dogs of each group were treated in five treatment groups (ivermectin, YN oil, YN oil+WC, YN oil+MG, and YN oil+WC+MG) for 1 month. The individual dogs were clinically evaluated, and the dermatological lesions were monitored daily for 60 days.
Results: Dermatological lesion improvement was predominantly observed in the group of dogs treated with YN oil+WC. This was evidenced by the disappearance of the hyperpigmentation and lichenification on day 28 post-treatment and alopecia on day 56 post-treatment. Moreover, no allergic or clinical signs were observed during treatment.
Conclusion: YN oil+WC is an alternative herbal medicine that could be used for the treatment of localized canine demodicosis.
