Patterdales are a type rather than a breed though they’ve been around since the late 1800s as a hard-working terrier. Their original job involved fearlessly going to ground, down tight holes underground, as well as following quarry above ground. This meant they needed a tough weather-proof, thorn-proof coat, a decent length of leg, narrow chest and powerful jaws.
Today’s Patterdale is typically a robust terrier, with a smooth hard coat, or a tight rough coat, or occasionally a mix between the two. They are brimming with mischief - and are lightning-fast at decision making and reacting which can make them a challenge to train and live with.
