  • Progressive weight loss and muscle weakness.

  • Skin lesions on face and ears.

  • Hair loss, scabs and non-healing wounds.

  • Abnormal nail growth or nosebleeds.

  • Inflammation of lymph nodes.

If you notice any of these signs, go to a doctor as soon as possible. general practice. At Benivet Benissa we carry out specific laboratory tests to confirm the infection and determine the general condition of your pet.

According to the World Health Organisation (WHO)Leishmaniasis is one of the main zoonoses at a global level, which reinforces the importance of prevention in endemic areas such as the Valencian Community.

When is canine leishmaniasis control necessary?

Leishmaniasis requires a preventive approach and proper veterinary monitoring to detect the disease early and maintain the dog's quality of life.

Prevention of leishmaniasis

In areas where leishmaniasis is endemic, prevention is key even in apparently healthy dogs.

  • Use of phlebotomine sandfly preventive measures

  • Regular veterinary checks

  • Dogs living in or travelling to risk areas

Early diagnosis of leishmaniasis

Early detection allows disease control to be initiated before the onset of severe symptoms.

  • Control analytics

  • Dogs with positive test results

  • Assessment after exposure to the vector

Monitoring of dogs with leishmaniasis

Diagnosed dogs require regular check-ups to adjust treatment and prevent complications.

  • Periodic analytical control

  • Adjustment of treatment according to evolution

  • Improving and maintaining quality of life

What does it mean if a dog tests positive for leishmaniasis?

A positive result indicates that signs of infection or contact with Leishmania, but this does not always mean that the dog has an active clinical disease. Some infected animals may appear healthy, whilst others show symptoms or abnormalities in their test results.

For this reason, a test result must be interpreted in conjunction with the veterinary examination, the symptoms, the antibody level and any possible abnormalities in organs such as the kidneys. LeishVet’s recommendations distinguish between infection and clinical disease, and point out that a single test result may require further testing to assess each case correctly.

What should we do after a positive test result?

The next step depends on the dog’s general condition and the type of test carried out. The assessment may include:

  • Review of symptoms and medical history: Let’s start with a veterinary practice in Benissa to assess weight loss, skin lesions, lethargy, eye abnormalities, nosebleeds or other possible signs.

  • Assessment of general condition: a blood tests It enables the analysis of haematological and biochemical parameters and allows us to check for any associated abnormalities.

  • Monitoring of kidney function: on urinalysis It helps to identify changes that may affect treatment, follow-up and prognosis.

  • Confirmation or extension of the study: Depending on the initial result, the patient’s symptoms and medical history, it may be necessary to repeat the test or request further investigations.

  • Clinical status classification: Not all dogs that test positive require the same management. Treatment and the frequency of check-ups are tailored to the severity of the condition and the progress of each patient.

  • Personalised support: Where there is a clinical condition or organ involvement, we coordinate the management from the veterinary internal medicine.

Does a dog that has tested positive need immediate treatment?

Not necessarily. The decision should not be based solely on a positive test result. Some dogs may need treatment, whilst others require confirmation, regular check-ups and monitoring for any clinical or laboratory changes.

Even when a dog is already infected, it is important to ensure it remains adequately protected against sand fly bites. We can review its plan for veterinary deworming and assess which preventive measures are appropriate for their situation. LeishVet recommends continuing to use repellent on infected dogs as well, to reduce their exposure to further bites.

If your dog has tested positive or you need a second opinion, please bring any previous reports and test results so that we can review the full case.

Estamos muy agradecidos con el equipo de Benivet Benissa por la atención y el cuidado que han tenido con nuestro perro. Llegamos a la clínica después de varias semanas de problemas en la piel y de haber probado diferentes tratamientos sin conseguir una mejoría real. Nuestro Yorkshire, que ya tiene 14 años, tenía heridas, zonas muy inflamadas y pérdida de pelo. En Benivet realizaron las pruebas necesarias y finalmente encontraron la causa: una demodicosis grave con una infección bacteriana secundaria. Nos explicaron todo con mucha claridad y empezamos un tratamiento específico. Aunque el tratamiento todavía no ha terminado, la mejoría ha sido enorme: las heridas han desaparecido, la piel está mucho mejor, las zonas oscuras de las patas están desapareciendo y el pelo ya está empezando a crecer de nuevo. En la última revisión todavía quedaban algunas bacterias, por lo que nos han prolongado el tratamiento una semana más. Queremos agradecer especialmente la profesionalidad, la atención y la paciencia que han tenido con nosotros y con nuestro pequeño. Después de todo lo que habíamos pasado, por fin sentimos que nuestro perro está en buenas manos. ❤️ Muchas gracias a todo el equipo de Benivet Benissa. 🐶❤️

Durante los últimos dos meses hemos vivido momentos muy difíciles y llenos de incertidumbre. Nuestro galgo macho de 5 años se rompió una pata y además tenía un tumor. Para resumir una historia bastante larga: afortunadamente resultó no ser cáncer, pero finalmente tuvieron que amputarle la pata y ha pasado por momentos de mucho dolor. Estamos enormemente impresionados y agradecidos con todo el personal de esta clínica. Tanto el equipo de veterinarios como el personal de apoyo se comunican perfectamente, son muy empáticos y atentos, pero al mismo tiempo proactivos y tremendamente profesionales. Sinceramente, no tenemos ni un solo punto de crítica. Estamos simplemente muy felices de haber llegado a esta clínica y, sin ninguna duda, a partir de ahora serán nuestros veterinarios de confianza. **Gracias por todo, querido equipo de la Clínica Veterinaria Benivet.** ❤️ Willem y Javi

Fuimos el viernes por la tarde porque nuestro gato se comió un hilo largo. Las veterinarias fueron súper pacientes a pesar de que el gato se puso peleón por el miedo. Le hicieron ecografía y luego lo metieron a cirugía casi inmediatamente. El cirujano fue excelente, nos explicó todo el procedimiento y nos avisó por WhatsApp cuando estuvo listo el gatito, se quedó en observación y al día siguiente lo hemos recogido. La operación fue impecable y el gatito está en casa, la sutura está perfecta. Fueron excepcionales.

Lleve a mi gato de 6 años de urgencia porque se había tragado un hilo largo y gordito, y por la mañana vomitó un trozo. Menos mal que lo hice ya que al día siguiente era festivo, y haber esperado más habría resultado seguramente en necrosis y perforaciones intestinales. Mi gatito fue muy bien atendido por todos los veterinarios. Lo sedaron porque estaba nervioso, le hicieron ecografía para encontrar el hilo en el yeyuno, ya medio plegado, y lo operaron. Fue caro pero lo pagaría de nuevo, porque la vida de mi gatito no tiene precio y lo atendieron aún cuando iban a empezar después de su hora de cierre. Además está mañana al recogerlo estaba bien, tranquilo y dolorido, y la sutura se ve super limpia y bien hecha. Mis agradecimientos a Constantino y al resto de veterinarias que atendieron a mi gato.

No tenemos más que agradecimiento para todo el equipo de Benivet Benissa. Llevamos a nuestro perro Dachs para una cirugía de columna delicada —una hernia que le comprimía la médula— y desde el primer minuto nos transmitieron una tranquilidad enorme. Incluso nos avisaron de la dirección exacta para no confundirnos con otra clínica que hay a pocos metros: un detalle pequeño que ya dice mucho de cómo trabajan. Queremos destacar especialmente a dos personas. Al traumólogo, Constantino, que hizo un trabajo impecable: retiró toda la hernia y liberó la médula sin complicaciones. Y a la anestesista, Ana, que cuidó cada detalle —algo nada menor en una intervención así—. Gracias a ambos, en las primeras 24 horas Dachs ya recuperaba movilidad voluntaria en la pata. Cuando surgió un pequeño imprevisto con la sonda, lo resolvieron al momento y con total profesionalidad. Pero si algo destaca por encima de lo médico es el trato humano de todo el equipo. Nos mantuvieron informados con mensajes constantes y cercanos, nos escribían para contarnos que Dachs "se portaba muy bien", que nos deseaba buenas noches, e incluso se adelantaron ofreciéndonos un arnés de apoyo por si lo necesitaba. Se nota que aquí no solo tratan a los animales: los cuidan de verdad. Gracias de corazón a Constantino, a Ana y a todo el equipo de Benivet.

Muy contento con benivet, un buen servicio y mis animales están en muy buenas manos con ellas. De lo mejor de la zona.

How do we diagnose leishmaniasis and what tests may be indicated?

The leishmaniasis requires an orderly approach: assess symptoms, confirm infection and measure the impact on organs (especially kidney and liver) in order to choose the appropriate treatment and follow-up. At Benivet Benissa, after the examination, we recommend the following tests only when they provide useful information:

Veterinary practice in BenissaMedical history (travel, risk by area/endemic), complete examination and prioritisation of the plan.

Blood testsThe basis for diagnosis and follow-up (general condition, inflammation and, above all, assessment of organic involvement).

UrinalysisThe key to assessing renal function and detecting alterations that condition prognosis and treatment.

Microscopy and cytologyin selected cases (e.g. skin lesions or lymph nodes) to complete the study when needed.

If skin lesions, itchiness or alopecia predominate, we also coordinate with veterinary dermatology to treat skin complications.

For prevention in endemic areas, we reviewed the preventive plan with veterinary deworming (protection against sandflies) and, if appropriate to the timetable and risk, with veterinary vaccination.

If the case requires long-term monitoring or follow-up of organs, we coordinate it from veterinary internal medicine. And if the patient is unstable or in need of fluid therapy/monitoring, we can rely on veterinary hospitalisation.

👉 If you want an assessment or a control test, request an appointment here or call +34 622 325 271.

Frequently asked questions about leishmaniasis in dogs and cats

Leishmaniasis is transmitted through the bite of the phlebotomusa small mosquito that is very common in warm areas such as the Costa Blanca. It is not spread directly between dogs or from dogs to people; the insect vector is always involved. Prevention is essential to avoid the disease.

The signs can be very varied: weight lossSome dogs have mild symptoms for months, so regular check-ups are key to detecting it early. Some dogs have mild symptoms for months, so regular check-ups are key to early detection.

The diagnosis is based on blood testsWe recommend a clinical assessment and, if necessary, complementary tests such as cytology or specific profiles to assess the renal and hepatic status. We also recommend performing annual testeven if the dog is protected, for early detection.

Leishmaniasis is often not completely curedHowever, with proper treatment, most dogs can live a long and stable life. The aim is to control the disease, reduce symptoms and monitor for relapses through regular check-ups.

Prevention combines several methods:

  • Repellent collars and pipettes specific

  • Vaccination against leishmaniasis

  • Avoid walks at dawn and dusk.when the phlebotomine sandfly is most active

  • Use of mosquito nets or avoidance of damp and wooded areas in risk months.
    Your vet will advise you on the best combination according to your lifestyle.

Although it is much less common than in dogs, cats can also become infected. They are generally more resistant, but may develop skin or eye symptoms. It is advisable to protect them in endemic areas and to consult if suspicious lesions appear.
