The brown dog tick is a tiny reddish brown tick that likes to drink the blood of dogs. It is only about as big as a sesame seed. It is special because it can live its whole life inside a house or a dog kennel.

Fun fact: this one is not an insect. It is an arachnid with eight legs, a cousin of the spiders.

Dangerous: look, do not touch
It can carry germs that make dogs and sometimes people very sick. Do not touch a tick yourself. Tell a grown-up, who can remove it safely and check your pet.

It drinks blood. Dogs are its favourite, but it can feed on many other furry animals too.

Ticks: how to stay safe

  • In Estonia, the castor bean tick and the taiga tick can carry Lyme disease and tick-borne encephalitis.
  • Ticks wait on grass stems, from ankle to knee height. Long trousers tucked into socks and light clothes help you spot them.
  • After playing outside, check your body, your hair and your pets for ticks.
  • Found a tick? A grown-up should take it out quickly with fine tweezers or a tick tool: hold it close to the skin and pull slowly. No oil or alcohol on it. Then wash the spot.
  • There is a vaccine against tick-borne encephalitis, for children too from one year old. Ask your doctor.
  • If in the weeks after a bite you get a fever, feel ill or see a red patch that grows, go to a doctor.
