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). Otomax is an ear medication for dogs prescribed for the treatment of ear infections (otitis externa). Otitis externa can 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. Otomax is available on Vetito veterinary pharmacy in an easy-to-apply ointment that combines a steroid, an antibacterial, and an anti-fungal. Otomax ointment quickly reduces inflammation, itching, and pain, while being effective against swelling, and bacterial and fungal infections.
