You love your dog’s ears so much! But so do bacteria and yeast. Your dog has deep ear canals that often do not get enough airflow, especially if he or she has floppy ears, which creates a moist, dark environment where bacteria and yeast thrive. Over time, this can turn into infections. If your dog is constantly shaking his head, scratching, and rubbing his ears, and if you notice discharge, redness, swelling, or odor, he may have an itchy and painful ear infection (otitis externa). Otitis externa can also be caused by allergies, ear mites, growing hair, trapped water, or a foreign body inside the ear. Frequent bathing, swimming, and incorrect cleaning can also be part of the problem. Posatex is an antibacterial, anti-inflammatory, and antifungal otic suspension for dogs, prescribed for the treatment of otitis externa. Posatex is available in powerful ear drops that quickly ease inflammation and pain. Just use Posatex once a day for seven days, and the infection should clear up.
