In common with most terrier dog breeds, the Airedale is confident, bold and outgoing. They are loyal, friendly, curious, energetic dogs who are fun loving, eager and tireless. They are devoted to their family and will protect them if they feel it is necessary. Airedale Terriers can sometimes be reserved with strangers and may not be entirely friendly to unknown dogs. While mostly kind and docile, they are the kind of plucky, fearless dogs that while they might not start a fight, will always finish one. A typical terrier, they may not be reliable with small furry animals and cats.
