| Examining
and Medicating the Ears of a Dog |
This information
is not meant to be a substitute for veterinary care. Always follow
the instructions provided by your veterinarian.
|
In the photographs
below, unless otherwise noted, the dog is facing with her nose
pointing to your right.
Variations on
these instructions exist.
Ear cleaning and medicating
can be messy so cover good clothes and work on a surface that is
easy to clean.
Most dogs do not like
having their ears cleaned. Some dogs will happily sit in
your lap or on a table while you clean or medicate their ears but
many require some form of restraint. |
|
One
method to restrain the dog is to place her/him on a table.
Stand on the side of the table opposite to the ear you
are medicating; in the photograph the left ear is being
medicated.
Drape
your right arm over the dog's shoulders. Wrap your left
arm around the head and neck and use the finger tips
of the left hand to push the ear flap back and up to
expose the inner surface of the ear. |
If the dog
tries to stand, lean your upper body over his/her shoulders to
prevent him/her from rising. |
|
If
your dog is too wiggly, try laying him/her on his/her side.
Reach over his/her neck with your left arm and firmly grasp
the elbow of the leg closest to the table. Always hold
the leg close to the elbow, NOT close to the toes.
Keep
your left elbow on his/her neck to prevent him/her
from picking up his/her head. Use the fingers of your
right hand to pull back the ear flap to expose the
inner side of the ear. If the ear flaps are long, you
can tuck the ear flap under your left elbow. |
Holding the
medication bottle in your right hand, place the prescribed number
of drops of medication into the ear canal. |
It is easier
to perform this procedure if you have a helper.
The ear has
3 major parts:
- outer ear
- middle
ear
- inner ear
The outer
ear consists of the ear flap (also called the pinna) which
can be upright (a prick ear) or floppy. The ear flap funnels
sound into the ear canal. Unlike humans that have a very short
ear canal, dogs have a long narrow ear canal that makes almost
a 90 degree bend as it travels to the deeper parts of the ear.
The outer
ear cannel is separated from the middle ear by a thin
membrane called the eardrum or tympanic membrane. The ear drum
is very fragile and can be damaged by ear disease or during ear
cleaning. The middle ear consists of 3 small bones, an air filled
cavity called the bulla and a thin tube (the eustachian tube)
leading from the bulla to the back of the mouth.
The inner
ear connects to the brain and contains nerves and centers for
balance and hearing. The following picture shows a diagram of
the right ear as it appears if you are looking at the dog's head
from the front. A CT scan of the head is pictured on the right.
Dogs have
many more ear problems than cats. Dogs with heavy floppy ears
have the most problems with ear infections. Some breeds have
lots of hair in and around the ear canal which causes them to
develop ear infections. Dogs that spend lots of time in the water
also are prone to developing ear infections.
Dogs with
skin allergies may have ear problems as part of the allergy. |
 |
|
The
outer ear flap is usually covered with fur.
If
the ear is itchy, scratching may result in hair loss
on the ear flap or at the base of the ear. Severe scratching
may also lead to tears at the edges of the ear. Ear
damage may lead to bleeding between the skin and cartilage
of the ear flap; a hematoma. The ear flap is swollen,
warm and painful. |
|
|
The
inner side of the ear should be a healthy pink color. A
small amount of black discharge may be observed.
Ear
infections may result in:
- redness
- discharge
- odor
- head
shaking
- ear
scratching
- rubbing
ears on the floor or other surfaces
|
|
Ear cleaning
solutions contain various chemicals and may contain drying agents.
Check with your veterinarian regarding which product to use and
how often to use it. Excessive ear cleaning can be damaging
to the ear.
If the "non-furred",
inner side of the ear flap contains lots of fur at the opening
to the ear canal, a few hairs at a time can be plucked. Lots
of hair at the opening to the ear canal reduces air flow into
the ear. Good air flow is important to maintaining a healthy
ear. |
|
The
ear wash solution is squeezed into the ear canal. A few
drops of ear wash should be applied to the inside of the
ear flap and then the tip of the ear wash bottle should
be inserted a few millimeters into the ear canal, to place
some of the wash solution down the ear canal. Be careful
not to tightly force the tip of the bottle into the ear
canal as forceful squeezing of the bottle with the
bottle wedged into the ear canal could rupture the ear
drum.
The
dog will usually shake its head as soon as the wash
is inserted into the ear, shaking out much of the solution. |
|
|
Massage
the base of the ear to distribute the wash solution throughout
the ear canal. Dogs usually like this part. |
|
|
Use
cotton balls to remove discharge from the inner side of
the ear flap. |
|

Ear
medications may contain several different drugs and may
be ointments (pictured on the left and in insert) or drops
(pictured on the right).
Ear
medications are most effective when placed in a clear
ear. If they are placed on top of ear wax or other
debris they will not be as effective. Your veterinarian
will give you instructions, if cleaning is needed before
ear medications are given.
Sometimes
your veterinarian will recommend a thorough ear exam
under sedation or anesthesia if:
- the
dog will not allow cleaning awake
- it
is suspected that a foreign body such as plant material
is inside the ear canal
- the
veterinarian needs to collect samples from the ear
for cytology or culture
|
|
|
Whether
using ointments or drops, place a small amount of medication
on the inside of the ear flap and the prescribed number
of drops into the ear canal. The tip of the ointment tube
or dropper should be placed a few millimeters into the
ear canal to assure that the medication goes into the ear
canal. If the ear is stretched away from the head, the
bend in the ear canal will straighten so that the medication
can be deposited over the entire ear canal.
DO
NOT place the long neck of the ointment tube as far
as it will go down the ear canal as you could puncture
the ear drum with it. |
|
|
Massage
the base of the ear to help distribute the medication into
the ear canal.
|
|
If the infection
is severe or involves the middle and inner ear, oral medications
may also be prescribed. Surgery is sometimes necessary if the
infection is in the middle ear. |
