kennel tick

Definition

A vernacular name for the brown dog tick, *Rhipicephalus sanguineus*, widely used in veterinary and medical entomology to emphasize its association with domestic dogs and human-made shelters. The name reflects this tick's unusual ability to complete its entire life cycle indoors in kennels, homes, and veterinary clinics—behavior that distinguishes it from most ixodid ticks, which require outdoor vegetation for questing and molting. Kennel ticks are vectors of *Ehrlichia canis* (canine ehrlichiosis), *Babesia canis* (babesiosis), and *Rickettsia rickettsii* (Rocky Mountain spotted fever), making them significant in companion-animal and public health.

Etymology

From "kennel" (dog shelter) + "tick," describing the species' indoor habitat preference.

Example

A veterinary clinic in Arizona experienced a persistent *Rhipicephalus sanguineus* infestation despite pesticide treatment; inspection revealed thousands of kennel ticks hiding in wall cracks and under baseboards, highlighting the species' endophilic behavior that earns it the common name.

Synonyms

• Brown dog tick

Usage Notes

Primarily a North American and veterinary usage; specialists may prefer the scientific name *Rhipicephalus sanguineus* in formal taxonomic contexts. The term emphasizes behavioral ecology (indoor infestation) rather than taxonomy. Not all populations of *R. sanguineus* are equally endophilic—tropical lineages are more strongly associated with kennel environments than temperate ones. The name is sometimes applied loosely to other dog-associated ticks, but in technical usage it specifically denotes *R. sanguineus*.
