What type of animal primarily benefits from deworming?

Deworming primarily benefits animals that are infested with parasitic worms. These parasites, which can include various types of nematodes, cestodes, and trematodes, reside within the host's gastrointestinal tract or other tissues and can significantly harm the host animal's health. Infestations can lead to a range of health problems, such as malnutrition, weakness, anemia, and even death if left untreated.

By administering dewormers, the parasitic load on the animal is reduced, allowing for improved nutrient absorption and overall health. This is especially critical in young, immature, or immunocompromised animals that might be more susceptible to the adverse effects of these parasites.

While other options mention conditions related to animal health, they do not directly address the need for deworming as effectively. For example, animals with strong immunity and healthy, active animals may not currently be facing issues with parasitic worms, and those with skin infections require different treatments that focus on dermatological conditions rather than addressing internal parasites.
