Tick for small dogs - Yorkie Guide. What are dog ticks?
Ticks are eight-legged parasites that bite your dog to drink their blood. Although dog ticks are very tiny, they can swell up to the size of a pea once they’ve attached themselves to your dog by burying their mouthparts into their skin. There are several types of tick that can affect dogs in the UK, including dog ticks, sheep ticks and hedgehog ticks.
