What is Ectoparasite?
A parasite that lives on the surface of an animal's body, such as fleas, ticks, and mites, which can cause itching, allergies, and transmit other diseases.
Ectoparasites are organisms that live on the skin or coat of a host, feeding on blood or skin cells, in contrast to endoparasites, which live inside the animal's body. The most common in dogs and cats are fleas, ticks, and mange mites (Sarcoptes and Demodex, among others).
Beyond the direct discomfort caused by bites and itching, many ectoparasites are vectors for more serious diseases: ticks can transmit ehrlichiosis and babesiosis, and fleas can transmit tapeworm (Dipylidium caninum) when ingested during self-grooming. Heavily infested pets can develop flea allergy dermatitis (FAD), an intense allergic reaction to even a few bites, as well as anemia in cases of severe infestation, especially in puppies and kittens.
Control is achieved with regular antiparasitic products (collars, spot-on treatments, chewable tablets) prescribed by a veterinarian, who will also recommend the ideal frequency based on the pet's region and lifestyle. See a veterinarian if you notice intense itching, redness, hair loss in specific areas, or visible fleas and ticks on the pet, especially if there are signs of anemia, such as pale mucous membranes and lethargy.
