Tick
A blood-sucking acarid parasite. Ticks are larger then their relatives,
the mites.
These bad boys carry Lyme disease, Rocky
Mountain Spotted fever and Ehrlichia
and can cause tick paralysis in dogs.. They just sit on a blade of grass
for a very long time -
just waiting for a nice juicy dog to stroll by..
Earmite
Otodectes is a genus of mites that inhabit the surface of the ear
and
cause the ear infection Otoacariasis.
These cuties can travel back and forth between your pets. Head shaking,
itching and a blackish waxy goo in the ear canals are indications that
ear mites may have taken up residence in
your cat or dogs ears.
