Tick species identification

American dog tick

What to look for

A larger brown tick with mottled cream or gray markings on the shield behind the mouthparts.

Known disease associations

  • — Rocky Mountain spotted fever
  • — Tularemia

Finding this species does not mean the tick carried a pathogen or that transmission occurred.

Photos need context

Feeding, life stage, image angle, and damage can change how a tick looks. A useful identification weighs several visible traits together and states uncertainty when the photo does not show enough detail.
