The height ranges from 8.5–11.5 inches at the shoulder (21.5–29.2 cm) and weight from 3.5-9 pounds. They are in many ways similar to the Miniature Fox Terrier.
Temperament:
Toy Fox Terriers, like many active and intelligent breeds, can learn to respond to a number of words. Toy Fox Terriers were used commonly in circus shows by clowns, and they are said to make great companions for owners with a good sense of humor. As a terrier breed, they are often very active, though perhaps not as active as the Jack Russell Terrier, and are said to be well suited for older owners. They are quite trainable and often cited as making wonderful companions for people with disabilities. They are also very lovable and loyal to their owners. In addition, dogs of this breed tend not to bark very much if they are trained well.
Toy Fox Terriers adapt well to apartment life. They are active indoors and will do without a yard, as they can usually take care of their own exercise needs. They often have trouble tolerating cold weather without careful acclimation. Their life expectancy is about fifteen years (since the breed has only been officially recognized by groups like the UKC and the AKC since 2000, there is little official documentation). Toy Fox Terriers are significantly healthful and resilient, however, as with many toy breeds, some are prone to patellar luxation (slipped stifle). Legg-Calvé-Perthes syndrome and von Willebrand's disease are uncommon. Some dogs are allergic to beet pulp, corn, and wheat. The Toy Fox Terrier is easy to groom, although grooming is generally seen as unneeded due to how short the hairs are (under a centimetre in length most of the time). Sometimes, it is necessary to comb and brush the coat. The hairs shed very frequently.
