American Dog Tick

Natural Habitat

Tall grass, brushy areas, and wooded edges, popular in areas frequented by dogs and medium-to-large mammals.

Diet & Feeding

Obligate hematophagous; they feed exclusively on the blood of mammals, including humans, dogs, and wildlife.

Behavior Patterns

They exhibit 'questing' behavior—climbing to the tips of grass or shrubs and holding their front legs out to latch onto a passing host. They have a three-host life cycle (larva, nymph, adult).

Risks & Benefits

They are a primary vector for Rocky Mountain spotted fever and tularemia. They can also cause tick paralysis in dogs and humans. They provide no direct benefit to humans but serve as food for certain birds and reptiles.
