Ear
mites are small bugs that generally live and feed in an animals ears.
They can spread to other areas of the body in severe infestations, but
are usually confined to the ear area. Luckily ear mites don't
survive long off of the host animal, so they're relatively easy to control in
the environment.
There
are several types of mites that can live in the dog's ears, but
treatment is the same for all types. If your dog/puppy gets ear
mites, you will most likely need to treat all animals in the home as
ear mites will quickly spread between all of your pets. Besides
dogs, ear mite infestations can affect cats, ferrets, hamsters,
gerbils, rabbits, mice and rats. Humans are NOT at risk
for "catching" ear mites from their pets.

Dogs
with an ear mite infestation will scratch around their head/ears and
may shake their heads. The more sever the mite infestation, the
more scratching and shaking you will see. You may or may
not see the dog scratch other affected areas if the mites spread to
other parts of the body. Another sign of ear mites is a buildup
of debris (dried blood) within the ear canal. This debris will
look rather like coffee grounds. If you clean your dog's ears
and notice that more debris appears again within a day or two, then
your dog probably has ear mites. This debris can be similar to
the debris generated by a bacterial and/or yeast infection, so you
need to confirm the presence of mites to be sure you are correctly
treating your dog's ears. This will most likely mean you need to
take a trip to see your veterinarian.
In
some instances, it's possible for you to confirm the presence of mites
in your dog's ears. If your dog has a significant collection of
debris in the ears, it may be possible to see the mites within this debris.
To check for mites, use a Q-tip to swipe as much debris as possible from
the ear canal. Place the q-tip and debris on a dark piece of
paper. Ear mites will appear as VERY small moving white dots.
You can use a magnifying glass or microscope to help identify the
presence of mites.
Keep
in mind that even if you actually do see mites, your dog could have an
ear infection in addition to an ear mite infestation. Changes in
the ear environment from an ear mite infestation often lead to ear
infections. So, even if you confirm there are mites in your
dog's ears, a trip to the vet's is probably in order to be sure there
are no other problems that need to be addressed.

While
not a life-threatening emergency, ear mites are annoying and
uncomfortable for your pet. They are commonly seen in many
animals and can be extremely tough to get rid of permanently.
This is due, in part, to the fact that the affected animals must be
treated repeatedly (over a significant period of time) to kill not
only the adult mites but all newly hatched mites as well.
Treatment for ear mites must be continued until there is no
further evidence of infestation for at least 2 weeks.
If
you live close to other infested animals that are untreated (the
neighbor's dog) or if your dog is repeatedly in contact with stray
dogs or cats, then it can be difficult to permanently solve this
problem. Untreated,
infested dogs that come to visit or that your dog encounters/plays with
at the vet's, in obedience classes or while out walking can all pass
mites to your dog. Even if you have repeatedly treated your
dog for this problem, it's important to treat this issue as often as
necessary because untreated mite infestations can damage the ear eardrum
and/or the ear canals and can cause permanent hearing loss.
There are a number of over-the-counter and prescription ear treatments to kill
ear mites. These products usually contain a pyrethrin insecticide.
Using an insecticide is the only way to successfully treat an ear mite
problem. If you are looking for a product to treat your dog at
home, be sure to get the product with the highest percentage of
insecticide. Keep in mind however, that no amount of
insecticide will solve the problem if the product is not applied
correctly or for the necessary length of time. Additionally, you
must clean the ears well to be sure that the treatment gets down into
the ear to all the mites that are hiding in the ear debris and within
the canal.
Veterinary
treatment may include the use of a topical ear product named Tresaderm.
This product contains an antibiotic which may help in mite cases with
a secondary bacterial infection. It also has a cortisone
derivative that is beneficial for inflammation and thiabendazole to
kill yeasts and mites. This product and can also kill developing mite
eggs which reduces the length of time necessary for successful
treatment. Treatment is generally administered for 10-14 days.
The
heartworm/flea/tick preventative "Revolution" (selamectin) is promoted as being able to prevent ear mite infestation
and is simple to use since, with one application a month, it takes care
of this and several other pests as well. However, an existing ear
mite infestation must be treated with another product to immediately
solve the problem. Revolution would eventually resolve the issue,
but it would take 2-3 months of treatment to do so without spot treating
the ears themselves. Some veterinarians also use "Frontline" (Fipronil)
to treat ear mites.
Depending
on the product used, treatment may last for two to four weeks.
Follow your vet's or the label directions carefully and for the
recommended length of time. Since some ear mites may live on
other portions of the dog's body, you may need to treat additional
areas of your pet. These areas can include the feet and tail.
Personally, I think incorporating an all-over-the-body treatment at
least once a week during ear mite treatment helps control and resolve
this issue faster.
Products
that are designed to kill fleas and ticks (sprays, dips, and shampoos)
and which contain an insecticide will effectively kill mites.
I recommend Adams Flea and Tick Mist as a spot treatment or Adams Flea
and Tick shampoo or dip for all-over body treatment. If you use
a dip or shampoo to treat for mites on the body, the product must be
allowed to sit on the dog for 10 minutes before it is rinsed or
towel-dried off of the animal. Follow label directions, being
sure that the dog is wet and soapy all over and all the way to the
skin. Remember to treat all pets simultaneously since mites are
easily transferred between pets and mites from an untreated house mate
can re-infest a treated dog.

To
treat ear mites:
- Mix 1 part
injectable ivermectin with 20 parts propylene glycol.
- Instill 0.2 to
0.3 ml (4-6 drops) into each ear canal daily.
- Treat for 2
weeks.
I have also heard
of others using the pour-on form of cattle ivermectin for this purpose.
Keep in mind that some Collie, Sheepdog and Shepherd breeds and mixes
are ivermectin sensitive and can have fatal reactions to ivermectin.
- PARAFFIN/BENZYL BENZOATE:
Combine 8
parts liquid paraffin with 1 part benzyl benzoate to remove
debris and kill mites.
-
Clean ears with a regular ear cleaner.
-
Put 4-6 drops of almond or
olive oil into each ear daily.
-
Continue treatment for 3 to 4 weeks.
The oil will effectively smother the mites.
Without further irritation from active mites, inflammation should
subside. If there is a bacterial or yeast infection present,
you will need to address these issues as well.
