===Conjunctivitis===
Conjunctivitis is rarely seen in adults but can be seen in young animals and is often the result of a foreign body. A common example of this is dust bath sand causing irritation to the eye. Clinical signs including purulent conjunctivitis may indicate a bacterial infection with ''Staphylococcus sp'' and ''Pseudomonas aeruginosa'' species being reported.

Gross pathology may show eyes that have visible oedema, a hyperaemic conjunctiva and either a serous or purulent ocular discharge.
===Otitis Media===
Otitis media is common in younger animals and if often a secondary infection to a respiratory infection or other trauma. Depending on the severity and location of the infection neurological clinical signs may be apparent which include ataxia, circling or rolling.

Macroscopic pathology may include considerable scar tissue that can result in blockage of the ear canal. Where this occurs cerumen and debris are often trapped inside. The tympanic membrane is often thickened. The ear canal and tympanic membrane will be acutely inflammed. This inflammation may progress to the inner ear and/or meninges.
