Brown Dog Tick (Nymph) - Rhipicephalus sanguineus
I was surprised that we didn't have any photos of this species on JD because it is found worldwide...So, here it is.
Brown dog ticks are easy to recognize because they are brown, lack ornamentation, and have a hexagonal basis capituli. Adults grow to just over 3 mm in length.
It is medically significant in that it can transmit many pathogens to dogs that induce diseases, such as tick typhus, Rocky Mountain spotted fever, babesiosis, and ehrlichiosis.
