Although most ticks are found around the head and neck of the animal as well as inside the ears, they can end up anywhere on the body. It is especially important to search longhaired dogs very thoroughly between the eyes and the end of the nose. The most reliable way to locate the ticks is to systematically run your fingers through your cat or dog’s coat. We find using a tick hook like the green one shown below to be the most reliable way to remove ticks. If the head is left in, don’t worry as the tick will die and inject no more poison. Always assume there is more than one tick and continue your systematic search.
It is true that animals can develop an immunity to tick poison, but it requires repeated mild poisoning and may last only one season. Even those animals that do build up an immunity can still wind up paralysed if they’re bitten by multiple ticks or a particularly toxic one. So it’s not a good idea to count on your pet being one of the lucky ones.
