Dogs are suseptable to Mange mites
Sarcoptes Scabiei  

(Canine Scabies)
Sarcoptic mange is a contagious skin disease in dogs,
caused by the Sarcoptes Scabiei mite. These mites will burrow
into the skin causing intense itching and irritation.
The scratching that results is the causes the of the
hair to fall out. This is a treatable medical condition,
but is highly contagious to other mammals to include human animals.
The animal should be
quarantined while being treated.

Life Cycle
The mites usually spend their life on the host.
The female mite burrows into the skin and lays her eggs
several times as she continues burrowing. These tunnels can actually
reach the length of several centimeters. After she deposits the eggs,
the female mite dies. In 3-8 days the eggs hatch into larvae.
The larvae mature into nymphs.
The nymph then molts into an adult  all while in the burrow.
The adults mate, and the process continues.
The life cycle requires 2-3 weeks.

The mites prefer to live on the host, but can live several
days off the host in a suitable environment.  Cool moist environments
a mite can live for up to 22 days. At room temperature
they will live from 2 to 6 days. The mite's
ability to survive without a host means
a dog can become infected without
direct contact with a infected animal.

Symptoms
The symptoms include hair loss and
severe itching on the elbows, ears, armpits, hocks, chest and
abdomen. The mites like to live on areas  that have less hair.
As the infection worsens it can spread over the entire body.
Small red pustules often develop  with
yellow crust on the skin from the mites burrowing. Because of the severe
itching and scratching the skin soon becomes
traumatized and a variety of surface infections can develop.
If it is mistakenly treated as an allergy
the skin may darken and the surrounding
lymph glands may become swollen.

Sarcoptic mange is a common infestation and
have often been misdiagnosed as severe a allergy.
If your dog does not have a prior history of allergies
and develops severe itching, or if the itching is not seasonal
but year round suspect sarcoptic mange.
The intense itching is from a severe allergic reaction to the mite.

Diagnosing

The standard method is a skin scraping and
then identify under the microscope.
But only  20% of infected dogs
will show Sarcoptes mites on a scraping.
Therefore most diagnoses are made based on
history and response to treatment for scabies.

Treating Sarcoptic Mange

There are several ways to treat scabies.
We watched a veterinarian use a pig wormer shot just under
the skin of a dog and it was completely cleared with one shot.
In the past, the most effective treatment had been to clip the dog
if it had long hair,  then dip the dog with a insecticide.
Lime sulfur dips have also been used effectively.
The animals are usually dipped every two weeks for
two to three times. These dips are very difficult
to apply for both the owner and the dog.
Because you have to get the dip in contact
with the face and ears of dogs,
great care has to be exercised when using.
The dips were toxic to human animals and are not
usable on very young, old, or unhealthy dogs.
There are newer products that are effective, safe, and convenient in treating mange.
The most widely used is ivermectin.
Designed as a cattle wormer this product has
found many uses in dog treatments at lower doses.
Ivermectin should never be used in collies or Shetland sheep dogs
and should be used with caution in the herding breeds
since these dogs are sensitive to the active ingredient.
Milbemycin oxime is used in cases where Ivermectin cannot be utilized.
The only preventative i heard about has been a new product called selamectin (Revolution).
A topical medication that is used to prevent  heart worms, fleas, and some tick protection.

Prevention
Keep your dog away from other dogs and animals.
Follow through on preventative medications
If you think there maybe a sarcoptic Mange problem
in your area a yard pesticide permethrin works well and
also prevents other parasites from living near your home.

Dogs that are well cared for, eat a good diet,
have a healthy skin and coat,
and don't spend time with other dogs
or where dogs are brought together,
are less likely to contract this disease.

Human Animals and Sarcoptic mange

Yes you can get infected from your dog or someone else's
The disease is generally self-limiting,
causing only temporary itching.
Human Animals have their own Sarcoptes, which is transmitted
from person to person. This human animal sarcoptic mite causes
a rash on the wrists, elbows, or between the fingers.
In Human Animal  infants, the rash may appear on the head, neck, or body.
