American dog tick
The American dog tick is a small, flat crawler that drinks blood. It waits in long grass and bushes and climbs onto dogs and people who walk by. It is a cousin of spiders, so a grown-up tick has eight legs.

How fast is it?
Fun facts
A baby tick has only six legs. It gets its last two legs when it grows into the next stage.
A tick has to hold on for hours before it can pass on an illness, so taking it off early really helps.
It likes to feed on the same kind of animal all its life.
Ticks do not like short, dry grass. Mowing the lawn keeps fewer ticks around.
Most asked questions about American dog tick
?How do I keep ticks away from my dog?
Check your dog and yourself after walks in grass or woods, and ask a vet about tick collars or drops.
?Is a tick an insect?
No. A grown-up tick has eight legs, so it is a relative of spiders.
Myth buster
Myth: Every tick gives you Lyme disease.
Truth: No. The American dog tick is not good at spreading Lyme disease. It can carry other illnesses, though, so it is still smart to check for ticks.
