Rhipicephalus sanguineus, commonly known as the brown dog tick, is an ectoparasite found worldwide in warmer climates. It primarily infests dogs but can occasionally bite humans. This tick is adapted to indoor living, thriving in homes and kennels. It is known for its reddish-brown color and oval-shaped body.

Rhipicephalus sanguineus, commonly known as the brown dog tick, is believed to have originated in the Mediterranean region. However, it is now found worldwide, particularly in warmer climates. Its geographical distribution includes continents such as Africa, Europe, Asia, the Americas, and Australia. It is predominantly present in regions with a subtropical or tropical climate.

The brown dog tick typically inhabits environments that are warm and dry. It is often found in areas with temperatures ranging from 20°C to 35°C (68°F to 95°F), and it thrives in regions with low humidity levels. While it is adaptable to various environments, it is commonly associated with domestic settings, particularly those with dogs.

Rhipicephalus sanguineus primarily targets dogs as hosts, although it can also infest other mammals, including humans. Its ecological niche involves residing in close proximity to its host, often indoors in kennels, homes, and dog shelters. It is well-adapted to human-modified environments and relies on domestic animals for its life cycle, making it a common pest in areas with high dog populations.
