Babesia canis is a protozoal parasite which infects red blood cells and can lead to anemia.[1] This is a species that falls under the overarching genus Babesia. Babesia canis is transmitted by the brown dog tick (Rhipicephalus sanguineus) and is one of the most common piroplasm infections.[2] The brown dog tick is adapted to warmer climate, therefore most infections come from the southern and southeastern United States and from California, especially in shelters and greyhound kennels.[2] Babesia canis is also predominately in Europe[3] and transmitted by Dermacentor ticks with an alarming increase in infections due to people traveling with their pets.[4]
