The first symbol stands for the first mentioned organism +/-. It is parasitism when ticks interact with dogs (ectoparasite).
Ticks cling to dogs by burying their mouthparts in the animal's skin. Many ticks produce a substance that is similar to glue that helps them stick together. Ticks begin feeding on the blood of your dog as soon as they attach. Where they attach, tick bites can itch and turn red.
This tick is a dog parasite that can sporadically infect humans as well as other hosts. Additionally, Coxiella burnetii, Ehrlichia canis, Rickettsia conorii, and Rickettsia rickettsii are only a few of the disease agents that Rh. sanguineus is a vector for.
