Breed history may initially seem rather unimportant to prospective pet owners, but looking at history is paramount to selecting the right companion. As pets, Airedales and Welsh terriers have different needs and personalities. Living with and training a Welsh terrier is different than living with and training an Airedale. Both are wonderful examples of everything that is loved about terriers: their intelligence, drive, energy, and hilariously creative ways of thinking. But a quick look at the differing histories of the breeds can give one a good idea of just how unique each breed is.
