The Miniature Fox Terrier is a small, lightweight, working terrier, known in its native Australia as the "Mini Foxie" They were developed as vermin routers and hunters. Its ancestors were most likely smaller Fox Terriers and other terriers, such as the Manchester Terrier. Later, further toy crosses were added, such as the English Toy Terrier. Although its ancestors are English, the Miniature Fox Terrier was developed in Australia. Hunters wanted a smaller Fox Terrier that could be used for hunting smaller pests, such as rats and rabbits. By the 1800's the breed was already clearly identifiable and had earned its worth against rabbits, rats, and snakes on Australian farms. The Miniature Fox Terrier also showed endurance and extreme loyalty to their owners.

    By the 1920's Miniature Fox Terriers had begun to find homes in the urban life, though many are still found on farms today. The qualities that made them valuable in the past are still in their bloodlines. They are fiercely loyal to their owners, and owner's property. They are inquisitive and bold, and make good pets. Generally they do get along well with other animals, however, as with most working terriers, they should never be left with small pets, such as rodents and reptiles, as they will always be seen as vermin to a Miniature Fox Terrier.

    Miniature Fox Terriers have short, fine coats with three color combinations, black and white, tan and white, and tricolor (black, white, and tan). They have a distinctive head with erect ears that stand up or fold only at the tips. Natural bobtails are known to occur with Miniature Fox Terriers.   

    Normally the Miniature Fox Terrier is a healthy, hardy breed. Some are afflicted with a luxating patella, a common ailment with small breeds, and even more so with puppy mill bred dogs. Most reputable breeders will health screen individuals. Miniature Fox Terriers live on average 14 years, and older dogs are not uncommon.
