The best ear infection treatment for a dog is to take him or her to the veterinarian. The veterinarian is able to run tests to determine what type of ear infection the dog has and can then recommend an appropriate treatment.
Dogs may get bacterial or fungal ear infections. Antibiotics are typically prescribed to treat a bacterial infection. Fungal infections, such as those caused by yeast, typically need to be treated with an antifungal medication. The veterinarian provides the owner with instructions on how to use either medication and can communicate the best way to prevent future ear infections in the dog.
