External parasites

External parasites are organisms that live on the skin or coat of our pets, feeding on their blood or tissues. The most common in dogs and cats are fleas, ticks, mites and mosquitoes. Although they are often associated with mild discomfort, they can be responsible for significant health problems.

One of the most important aspects is their role as vectors of disease. Fleas, in addition to causing intense itching and allergic dermatitis, can transmit Dipylidium caninum (a type of tapeworm) and, in some cases, bacteria such as Bartonella. Ticks are particularly concerning, as they can transmit serious diseases such as ehrlichiosis, babesiosis and anaplasmosis, which affect the blood system and may cause fever, anemia, weakness and even more severe complications if not treated in time.

Mosquitoes, on the other hand, act as vectors of major diseases such as leishmaniasis or dirofilariasis (commonly known as “heartworm disease”), a condition that affects the cardiovascular system and can seriously compromise the animal’s life. Mites, although they do not usually transmit systemic diseases, are responsible for conditions such as mange or parasitic otitis, causing intense discomfort, inflammation and skin lesions.

Symptoms of an infestation may include excessive scratching, redness of the skin, scabs, hair loss or the visible presence of parasites.

Prevention is essential and should be maintained throughout the year. There are different options such as spot-on treatments, collars or oral antiparasitic medications that protect against various types of parasites. It is also important to regularly check our pets, especially after walks in areas with vegetation.

At Hospital Veterinari Costa Brava, we help you choose the most suitable antiparasitic plan for your pet. Prevention is the best way to protect their health and ensure their wellbeing.
