Ticks

This parasite swells to the size of a small pea when feeding
Ticks are eight-legged creatures that are related to the spider family. A dog may get ticks on his coat by brushing against shrubs that are infested with them. The types of ticks that may affect a dog will depend on where he is living.

In the UK,  the most common tick parasites of dogs are the sheep tick, and the hedgehog tick.

These have hairless or short- haired, leathery bodies and spend they're lives in the environment, only visiting dogs or other animals for a few days in the spring or autumn in order to feed.
