Background: The numbers of dermatoses cases in veterinary hospitals are high. Canine&nbsp;dermatoses can have a serious negative effect on a dog&rsquo;s health and well-being, causing pain, discomfort and reduced quality of life. Furthermore, several dermatoses may be zoonotic, posing a risk to human health. To ascertain the epidemiology of dermatological disorders in dogs in Aizawl, Mizoram, the research work was done. 
 
Methods: The study was conducted between November 2023 to October 2024 at Veterinary Clinical Complex, Central agricultural university, Aizawl, Mizoram by clinical evaluation of each case, physical examination and data collection like age, breed, sex, body weight, deworming and types of diet. Different skin diseases were separated like bacterial, parasitic and others.&nbsp;&nbsp; 
 
Result: The hospital-based incidence of dermatoses in canine was found 14.6% with different etiology in Aizawl, Mizoram. The infection was more recorded in dogs between 2 to 8 years of age (5.18%), more in females (8.73%) and more in the mixed breed (8.46%) of dogs.

Background: Sex hormone dermatoses are uncommon in dog and causes overproduction of one or more of the sex hormones or exogenous administration. Ovarian cyst-induced hyperestrogenemia increased cortisol, hypertestosteronemia, and skin lesions mostly underwent undiagnosed and untreated. This case was documented as clinical pathological changes, diagnosis, and treatment of sex hormone imbalance-induced dermatosis due to an ovarian follicular cyst in a Labrador Retriever bitch.

Methods: This clinical investigation was carried out in the month of April&rsquo;2022 at Veterinary Clinical Complex, Veterinary College and Research Institute, Tirunelveli with a history of prolonged proestrus bleeding, perineal pruritus with reddening, swelling, and enlargement of the vulva. Vaginal exfoliative cytology, hormonal assay, ultrasonography, histopathology of skin, and haemato-biochemistry were performed.

Result: Physical examination revealed hyperpigmentation and hyperkeratinization of the skin. Vaginal exfoliative cytology and progesterone assay revealed cytological estrus. Ultrasonography revealed &gt;10 mm-sized anechoic structures in both ovaries along with uterine endometrial hyperplasia. Hormonal analysis revealed hyperestrogenemia and increased cortisol and testosterone. A biopsy of the perineal skin revealed hyperplasia and hyperkeratosis. The case was confirmed as sex hormone imbalance-induced dermatosis due to an ovarian follicular cyst. The animal was treated with two shots of Inj. hCG 500IU in 48 hrs interval followed by OHE after three months.
