Canine leishmaniasis

Leishmaniasis is a zoonotic parasitic disease transmitted through the bites of the phlebotomine sand flies and is the third most important disease worldwide. Travelling abroad, especially to the Mediterranean, might expose your dog to this severe, often fatal disease.

How is Canine Leishmaniasis spread?

The disease is carried from dog to dog by a microscopic parasite called Leishmania infantum, which is spread by sand fly bites. When an infected sand fly bites a dog, parasites are deposited on the skin.
A tiny skin lesion - called a chancre - appears at the site of the bite, usually in the muzzle or the ear. The parasite then invades the dog's cells, spreads into the internal organs and may begin to damage the immune system.








What are the signs and symptoms of Canine Leishmaniasis?

Signs of the disease are highly variable and in some cases, may take several years to manifest. Affected dogs may have a fever, show signs of hair loss (particularly around the eyes), lose weight and develop skin sores and nail disease. Unfortunately, over time, many organs may become involved leading to problems like anaemia, arthritis in many joints, eye and kidney disease.

How do I stop my dog getting Canine Leishmaniasis?

Treatment of Canine Leishmaniasis may be complex and often non curative, so prevention is best. You can help protect your dog from sand flies for the whole of the sand fly season, by using a collar containing deltamethrin, which also controls infestation with ticks for five to six months.
