Prevent Leishmaniasis in dogs

Canine Leishmaniasis is a serious parasitic disease in the dog caused by caused by a mosquito bite. The veterinarian Jose Rial Cels, responsible for general surgery, traumatology, neurosurgery and endoscopy at the Marina Baixa Veterinary Hospital, tells us more about this disease.


With the spring comes the time of the Phlebotomus mosquito, transmitter of canine Leishmaniosis. This disease is caused by the parasite of the genus Leishmania. It is a disease that affects various organs of the dog’s body and if left untreated can be deadly. The treatment is complicated and long lasting, and sometimes for life. Leishmaniosis has multiple signs:


  • Cutaneous and ocular lesions, such as blepharitis, conjunctivitis, dermatitis, abnormal nail growth, etcetera.
  • Nosebleeds.
  • Inflammation of the lymph nodes.
  • Lameness caused by arthritis.
  • Anaemia.
  • Renal or hepatic failure.


The Phlebotomus mosquito, known with sandflies, are the transmitters of Leishmaniosis. They are nocturnal insects so their activity begins at sunset. They feed on natural sources of sugar, but the females feed on blood to mature their eggs and thus transmit the disease. Its activity begins in spring with a maximum peak in June and July, but in autumn there is another peak of high activity. Therefore, it is advisable not to let your guard down until the end of October.


What can I do if my dog contracts Leishmaniasis?


The main way to prevent Leishmaniosis is to avoid exposing the dog to these mosquitoes. There are currently multiple repellent products based on pipettes or collars. The veterinarian is the only professional that can advise you which is the most appropriate preventive method for your dog. Nowadays, there is a vaccine against leishmaniasis, but it does not avoid the need to use repellents.


Do not forget that cats can very occasionally also be affected by Leishmaniosis. Therefore, we will also have to protect them from possible mosquito bites.
