Brown, yellow, black
brown exudate
smelly; yeast

coffee grounds; ear mites
how the normal tympanic membrane should appear when performing

problem of excess hair growth
traps in bacteria and yeast
What should be done to limit the potential problems that excess hair growth may cause?

Breaks down cerumen
how to make an “ear mite smear”

smear on slide
add mineral oil
apply coverslip
Malassezia
A form of yeast
precautions that must be taken when using “cotton tip applicators” to clean the
eternal ear canal
To not cause impaction or rupture the tympanic membrane
common ingredients found in ear cleaning agent

Antiseptic-kill bacteria
Drying agent-evaporate cleaner
Acidifier-change ph of ear environment

Elicit a startle response by clapping your hands
what symptoms might the animal display that would cause you to recognize the
existence of a possible ear infection
Shaking head, scratching/pawing at ears,
head tilt
two factors that predispose these breeds to a higher incidence of otitis externa
excessive hair growth and pendulent ears
Which direction will the infected ear be held
down
Give 3 areas that your oral and written instructions to the owner should cover
a. ear cleaning instructions
b. medication administration amount and frequency
c. Call if any problems within a determined number of days
