The causes of ear disease are complex. Each patient may have multiple contributing causes and factors. These are grouped in to primary and secondary causes and predisposing and perpetuating factors. Primary causes directly cause the ear to be “abnormal” with inflammation. Atopic disease (environmental allergies) and food allergies are two of the most common primary causes, although other causes, such as ear mites, do occur. Secondary causes develop in an abnormal ear and include infections with yeast and bacteria. Predisposing factors make ear disease more likely and include things such as narrow ear canals or pendulous ears. Perpetuating factors prevent the ear disease from resolving and include middle ear infections and chronic inflammatory changers. It is important for vets to identify which components affect the pet, and they may need to conduct several tests and recommend multiple management techniques.
Dechra has a range of topical treatments that target the secondary infections and inflammation. It is important for owners to apply the treatments as and when directed and to return for follow up assessments.
