What do you like about this subject?

Of all the diseases seen in dogs and cats, skin and ear diseases seem to fall into the number 1 and 2 categories.

What do you still hope to achieve/learn in this field?

There are a number of unanswered questions relating to why dogs and cats get ear disease. The bacteria and yeasts are hard to deal with and the area I am researching is how to treat these cases more effectively. I have designed the MedRx Video Vetscope, a video based imaging system for veterinarians to operate in the ear.

Something interesting about this subject that others may not know:

Dogs with ear infections that do not resolve within a month or 6 weeks usually have a middle ear infection as well. The eardrums rupture in response to external ear disease. Most people and vets do not know this.

Something controversial or provocative about this subject

Antibiotics alone are not the answer to ear diseases.
