What Are Parasites on Animals
Parasites on animals are organisms that live on or inside a host and feed at the host's expense. They range from tiny mites and ticks to worms and single-celled protozoa. These parasites can weaken the immune system, cause discomfort, and spread disease if left untreated.
Common Types of Animal Parasites
External parasites include fleas, ticks, lice, and mites that live on the skin or fur. Internal parasites often include roundworms, hookworms, tapeworms, and protozoa such as giardia. Different species tend to target specific hosts, though some can infect multiple animals or even humans.
Signs, Risks, and Prevention
Common signs of infestation include itching, hair loss, weight loss, diarrhea, and visible worms or eggs. Severe cases can lead to anemia or organ damage, especially in young or immunocompromised animals. Regular grooming, clean living areas, and veterinary check-ups help reduce risk. Veterinarians can recommend appropriate deworming and parasite control products based on the animal's species and environment.
