This
highly contagious condition is also called sarcoptic mange and is
caused by the mite Sarcoptes Scabiei which can also cause the same
condition in humans. The mite burrows under your dogs skin causing your
dog to itch frantically around the area of the infection.
The mites normally focus on burrowing around the face and head leaving
small tunnels as they burrow. Then the clear component in
blood known as serum will then rise to the surface through the tunnels
which causes the thick scabs and lesions on your dog's body.
As previously mentioned scabies or
mange
on dogs is highly contagious and
can be passed from dogs to humans. The mites have claw like hooks on
their legs also known as suctoral cups which helps the mites attach
themselves to their chosen host. The mites can actually live from
anywhere up to 21 days on the host without feeding.
Consequently the mites can be found anywhere in the House, in the
garden or on your dog's bedding.
