The Lancashire Heeler is a rare breed of small dog that hails from Great Britain. Bred to be a cattle dog, they are small enough to easily nip at the cow's hooves but quick and agile enough to move out of the way before getting kicked. When they weren't busy keeping the cows in line these little dogs also kept the farm free of vermin such as rats. They are a healthy breed, and they require minimal daily grooming, but they are not hypoallergenic. They tend to be friendly and affectionate with family, but can be wary of strangers, and benefit greatly from early socialization and training.
