[2] The brown dog tick is adapted to warmer climates and is found in both Europe and the United States, especially in shelters and greyhound kennels.

[2][3] In Europe, it is also transmitted by Dermacentor ticks with an increase in infections reported due to people traveling with their pets.

[7] The clinical signs of B. canis infection are lethargy, weakness, vomiting, anorexia, fever, pale mucous membranes, and dark discoloration of the urine.

[citation needed] B. canis is not easy to diagnose on a blood smear, since the chance of finding the parasite is low, due to its small size.

[6] In dogs infected with B. canis, splenectomy (removal of the spleen) or any immunosuppressive drug should be avoided; otherwise, signs of babesiosis may recur.
