I've had lots of experience with ear infections (otitis externa). Springer spaniels are notorious for them unfortuntely!!
My previous springer had antibiotic ear drops several times during her life. Although saying that, ear drops don't always resolve the problem because there are many potential causes. For example, parasites, foriegn bodies, allergies, yeast overgrowth etc etc. It can even be hormonal in some cases.
It may be that if the first course of antibiotics doesn't work, a culture and sensitivity may need to be performed so the correct antibiotic can be prescribed.
I make a habit of checking my dog's ears everyday. Keeping them clean and wax free is the best way to prevent infection from bacteria and yeast. I use Logic ear cleaner and since feeding Oscar a more holistic type diet, I don't seem to remove half as much wax from his ears.
Does your dog show other symptoms associated with a food intolerence Jenna??
