Which of the following is considered a tick-borne organism found in dogs?

Explanation:
Ehrlichia is a tick-borne bacterium that infects dogs and is transmitted by ticks such as the brown dog tick. It causes ehrlichiosis, which can present with fever, lethargy, and hematologic changes like thrombocytopenia. The other organisms listed are not primarily transmitted by ticks: Toxoplasma gondii is usually acquired from cat feces or undercooked meat; Isospora (Cystoisospora) is a protozoan spread via the fecal-oral route causing canine coccidiosis; Cryptosporidium is a waterborne protozoan infection. So Ehrlichia is the correct tick-borne option.
