Can We Minimize the Risk of Dogs Developing Canine Otitis Externa?—A Retrospective Study on 321 Dogs.

Simple Summary: In daily veterinary practice, canine otitis externa is a common presentation and, therefore, many studies were conducted to evaluate predispositions. This study on the other hand aims to evaluate factors that have potentially statistically reduced risks for developing otitis externa. Regarding the results, Rhodesian Ridgebacks and Collies have shown significantly low odds for otitis externa. Furthermore, regarding dogs with endocrinopathies, it was shown that those who are overweight seem to develop otitis externa more likely than those with a normal weight. Especially the latter result should be used in communication with pet owners to point out the importance of strict weight management and, therefore, increasing the quality of life of their dogs. Background: Canine otitis externa is a common presentation in small animal practice. The clinical signs vary individually from patient to patient. Regardless of the expression, they all decrease the quality of life. Therefore, this study aimed to identify factors that showed reduced odds for otitis externa. Methods: Clinical case records were searched for key terms regarding canine otitis. Statistical analyses were applied to evaluate associations with otitis externa. p-values of <0.05 were considered statistically significant. Results: Rhodesian Ridgeback and dogs with underlying infectious diseases had a reduced risk for otitis externa, while Retrievers and dogs with allergies had an increased risk. Furthermore, in the group of dogs with endocrinopathies, those with normal weight showed a reduced risk of developing canine otitis in comparison to those which were overweight. Conclusions: These results show a new point of view to reduce the prevalence of canine otitis by reducing the animals' weight due to an additional risk of otitis in obese or overweight dogs. Furthermore, for the first time, Rhodesian Ridgebacks were identified in our study population to have a lower risk of developing otitis externa. Thus, breeders should reflect—within other responsibilities for the quality of life in their offspring—on breed-specifics about otitis when planning ahead. [ABSTRACT FROM AUTHOR]
