7. Bedlington Terrier

With an arched back, a pear-shaped head, and a fleecy coat, the Bedlington Terrier looks remarkably like a small lamb. Do not let the gentle appearance fool you; bred to hunt rats in the copper mines of England, they possess the explosive speed and tenacity of a true terrier.

Their crisp, curly coat consists of a mixture of hard and soft hairs that stand off from the skin. Because the coat grows quickly, you need to schedule professional grooming appointments frequently. The traditional Bedlington trim features a shaved neck and a distinctive tasseled shape left on the tips of the ears.

Inside the house, they act as mild-mannered, affectionate companions who love lounging on soft furniture. Outside, they transform into lightning-fast runners who will happily give chase to any squirrel that crosses their path.
