This does not mean there are no concerns about resistance in 2021, resistance in hookworms, one intestinal parasite of dogs, was described. In small animals, where parasites can be a significant public health concern, it is a goal to kill all internal and external parasites.

This may include leaving a small population of worms untreated, so there always are susceptible worms in the overall population and we are not just continually killing off susceptible worms and leaving behind more and more resistant worms. In large animals, there is concern about resistance of parasites to available deworming medications and great attention is paid to minimizing development of resistant parasites. The biggest difference appears to be in overall management between large animals and small animals. This chapter will focus on demonstration of how your understanding of the life cycle of parasites for various species in different environments will help minimize infection or infestation and help with control of the parasite in the environment. Parasites, either internal (for example, worms) or external (for example, fleas and ticks), draw nutrients away from the host, and can cause disease. * Parasite Infection and Tools for Diagnosis
