A miniature Airedale terrier is actually a separate breed of dog known as the Welsh Terrier. The Welsh Terrier typically only weighs about 20 pounds and measures 15 inches tall as an adult.
The Welsh Terrier looks almost exactly like a miniature version of an Airedale Terrier, leading many people to mistakenly refer to these dogs as miniature Airedales. Welsh Terriers were developed in Wales, where they are still used to flush out game animals such as foxes, otters and badgers. They are fearless and lively, but they can be slightly difficult to housebreak. Their roots as hunting dogs make them eager to chase small animals, and they are prone to wandering off when not properly contained.
