 [ Symptoms ] how is an epidural steroid injection performed [ Disease ] well to start with how do you know your dog has an outer ear infection are you a veterinarian if not then i would suggest you have your dog properly diagnosed many conditions can look like an infection when they are something else entirely it would be unkind to treat your pet for a condition they may not even have second miconazole is an anti fungal medication it is not an antibiotic anti fungal medications treat conditions like ringworm athlete is foot and yeast infections antibiotics treat bacterial infections big difference so again i recommend you have your dog properly diagnosed before proceeding with any treatment i mean what is an outer ear infection  anyway are you talking about some condition affecting the flappy part of the dog is ears because that is not an outer ear condition it would be considered a skincoat condition if you are talking about a condition affecting structures inside the ear canal then you really should not be practicing home veterinary procedures you can easily injure a dog by placing medications swabs or other stuff into the ear their ears are not constructed like a human is wishing you and your dog well i totally understand a veteranarians passion for animals & i am sure they get tired of people pet owners trying to take matters into their own hands but i am not sure that the other persons question about her dogs ear warranted such sarcasm and rude reply at least she asked the question
