Ear problems are one of the most common ailments afflicting dogs. Whether due to infection, trauma, parasites or other diseases, ears can be trouble. Most often, the first signs is the presence of discharge from the ear. Sometimes, mild discharge is normal. Some dogs tend to produce more wax than other dogs. Keeping the ears clean helps prevent problems. For other dogs, ear discharge is often a sign of trouble-most often the dreaded ear infection. Dogs with ear problems usually start scratching when the trouble begins. The trauma of scratching causes swelling and discharge within the ear canal. The ears may then develop a secondary infection with either bacteria or yeast. Diseases that suppress the immune system and immune skin diseases can also lead to ear problems. Dogs with floppy, hairy ears and dogs that swim may be predisposed to developing ear infections and ear discharge.
