Canine atopic dermatitis and recurrent otitis

The development of canine atopic dermatitis (CAD) and recurrent otitis are frequently interrelated conditions in dogs, representing a significant challenge in veterinary diagnosis and treatment. This case study details the experience of a mixed-breed dog, adopted at one year of age, who suffers from CAD and frequent episodes of recurrent otitis caused by Malassezia sp. The objective of this study was to investigate the relationship between CAD and recurrent otitis, as well as to develop an integrated approach for the effective management of these conditions. The dog underwent a comprehensive clinical evaluation, which included a detailed history, observation of symptoms, and allergy testing. Treatment consisted of the use of antihistamines, corticosteroids and immunosuppressants, in addition to the application of monoclonal antibodies every four weeks to control itching. Immunotherapy has been introduced to modulate long-term immune response. Recurrent otitis was managed with regular cleansing and topical treatments with chlorhexidine, miconazole and omegas 3,6 and 9, applied three times a week, complemented by a restrictive diet to minimize food allergens. The results showed that the combination of these strategies provided significant relief from symptoms, improving quality of life. The integrated approach including environmental control, drug therapy and dietary management proved effective in controlling CAD and recurrent otitis. This study highlights the importance of personalized and ongoing management, as well as suggesting the need for more research into new therapeutic approaches for these chronic conditions. It is concluded that coordination between veterinarians and owners is essential for the success of the treatment and the well-being of affected dogs.
