Breed Profile:

Also known as the Amertoy (short for American Toy Fox Terrier), the Toy Fox Terrier is a descendant of the Smooth Fox Terrier which originated in England. He is a true American developed through a cross of small Smooth Fox Terriers with various types of toy breeds, including the Italian Greyhound, Miniature Pinscher, and the Chihuahua. Although smaller than the Smooth Fox Terrier, he is still a working terrier.

The Toy Fox Terrier remains playful all of his life. He is spirited, determined, easily trained, alert, loyal, fearless and very intelligent. He is a fast learner, eager to please, and adapts well to almost any situation. He makes a wonderful companion and is said to anticipate his master's moods and thoughts. He posesses the terrier's keen intelligence, courage and animation as well as the toy's devotion and loyalty to his family.

The Amertoy's appearance is athletic, graceful and agile, giving an impression of effortless movement, strength and stamina. His coat is short, satiny, fine in texture and smooth to touch. He is usually white with black and/or tan markings with the head mainly black or tan.

Health Issues

Though generally a healthy breed, the Toy Fox Terrier is susceptible to certain health problems, including:

  • Demodectic Mange — A skin disease caused by microscopic parasitic mites.
  • Patellar Luxation — A dislocation of the kneecap (patella). This may result from injury or from congenital deformities. All breeding dogs should be screened for Patellar Luxation.
  • Legg-Calve-Perthes Disease — Generally a disease of small breeds and often confused with congenital hip dysplasia.
  • von Willebrand's Disease — An autosomal recessive genetic disease. Affected animals suffer a condition which makes them more likely to bleed abnormally, similar in symptoms to Hemophilia in humans.

If you are considering the adoption of a Toy Fox Terrier puppy, or any breed, it is very important to be selective in choosing a responsible and reputable breeder. Ensure that the prospective puppy's parents have all health clearances. Breeding of any dog should not be done until after they have been proven to be free of evidence of significant hereditary diseases. (For more information on selecting a breeder, see the articles on the main Breed Listing and Breeders page.)
