| What are ticks?
Ticks are parasitic arthropods that feed on
the blood of their hosts. They are attracted
to warmth and motion, often seeking out
mammals – including dogs. Ticks tend to hide out
in tall grass or plants in wooded areas waiting
for prospective hosts. Once a host is found,
the tick climbs on and attaches its mouthparts
into the skin, beginning the blood meal.
Once locked in place, the tick will not detach
until its meal is complete. It may continue to
feed for several hours to days, depending on
the type of tick. On dogs, ticks often attach
themselves in crevices and/or areas with little
to no hair – typically in and around the ears,
the areas where the insides of the legs meet the
body, between the toes, and within skin folds.
Most species of ticks go through four life stages
- eggs, larvae, nymphs, and adults. All stage
beyond eggs will attach to a host for a blood
meal (and must do so on order to mature).
Depending on species, the life span of a tick
can be several months to years, and female
adults can lay hundreds to thousands of eggs at
a time. The following types of ticks are among
the most common seen in North America:
* Deer tick
* Brown dog tick
* Lone star tick
* American dog tick

The Dangers of Ticks.
Though they are known vectors of disease,
not all ticks transmit disease – in fact, many
ticks do not even carry diseases. However, the
threat of disease is always present where ticks
are concerned, and these risks should always
be taken seriously. Most tick-borne diseases
will take several hours to transmit to a host, so
the sooner a tick is located and removed, the
lower the risk of disease. The symptoms of most
tick-borne diseases include fever and lethargy,
though some can also cause weakness, lameness,
joint swelling and/or anemia. Signs may take
days, weeks or months to appear. Some ticks
can cause a temporary condition called "tick
paralysis," which is manifested by a gradual
onset of difficulty walking that may develop
into paralysis. These signs typically begin to
resolve after tick is removed. If you notice these
or any other signs of illness in your dog, contact
your veterinarian as soon as possible so the
proper testing and necessary treatments can
begin.
The following are some of the most common
tick-borne diseases:
* Lyme disease
* Ehrlichiosis
* Rocky Mountain spotted fever
* Anaplasmosis
* Babesiosis
