Introduction: This tick’s common name comes from the fact that it is only found in North America and that domestic dogs are the favorite host of the adults.

 Recognition: Unengorged adult female about 3/16” (5mm) long, male slightly smaller (about 1/8”/3.6 mm); engorged female up to about 5/8” (15 mm) long, 3/8” (10mm) wide. Body oval, dorsoventrally flattened (top to bottom). Color brown with whitish to grayish markings often with silvery hue.

 Habits: The American dog tick does not survive well indoors. If found indoors, it was probably carried in on a dog and dropped off when fully engorged to seek a suitable place for egg laying.
