Dog’s ears are impressive.
For example, they can swivel to locate the source of a sound in 6/100 of a second. However, the design of canine ear canals leaves something to be desired. Their shape (a downward plunge followed by a horizontal tract) can leave debris stuck too easily, which is why dogs—floppy-eared ones in particular—are prone to ear infections.
Telltale signs your dog has an ear infection include:
- ear scratching
- colored discharge
- crusted or scabby skin
- impaired hearing
- Also pay attention if your dog wipes his ear on the floor or furniture, or if he shakes his head a lot.
How to Prevent Ear Infections
Gently dry your dog’s ears after swimming or baths, and occasionally clean his ears with a cotton ball dampened with a solution recommended by your vet. If you suspect a problem, it’s important not to self-diagnose. Bacteria or yeast causes most ear infections, and both require veterinary treatment.
