Any organism that lives in or on another organism without benefiting the host organism; commonly refers to pathogens, most commonly in reference to protozoans and helminths.

In general there are two different groups or parasites: ectoparasites and endoparasites.

 Ectoparasites live on the host, affecting skin, fur, or ears. The most common ectoparasites of companion animals are fleas and ticks.

Endoparasites live inside the host, affecting the gastrointestinal tract, liver, or other internal organs. The most common endoparasites of companion animals and livestock are worms.
