Ticks

In Tasmania we have one type of Ixodes tick which can cause paralysis. Though generally not as severe as their mainland sisters, they can still cause paralysis and ultimately death of your pet if left untreated.

Female ticks attach onto the skin and secrete saliva into the bite site to prevent blood clotting so that they can have a nice long drink of blood. The saliva contains toxins which lead to paralysis. The long nerves are affected first – the hind legs and voice are usually the first areas to show change. Over time the paralysis creeps forward from the back legs until the entire body, including breathing muscles, are affected. Sometimes the toxins can directly affect the heart.
