Lifespan

In UK vet records, the typical Toy Fox Terrier lived to about 13 years, about average for a toy breed. The group was small, so treat the figure as rough.

Where it comes from

The Toy Fox Terrier was made in the United States by crossing the runts of Smooth Fox Terrier litters, prized for their pluck, with toy breeds such as the Chihuahua and Italian Greyhound. Its first job was killing rats around barns, and later its cleverness took it into circuses as a performer. The United Kennel Club registered them as Smooth Fox Terriers until 1936, when they gained their own name9,10.

The Toy Fox Terrier spent most of the twentieth century as an American farm and household dog, known mainly through the United Kennel Club, which kept its records after it gained its own name. Breeders gradually fixed a consistent type that kept the drive of its terrier ancestors in a much smaller frame. Wider recognition came in the early twenty-first century, when the American Kennel Club admitted it to its Toy Group. It is also known as the American Toy Terrier, sometimes shortened to Amertoy. Long kept as a ratter, it still has the quick reactions and persistence that made it useful around barns and outbuildings.

Breed standard

No FCI standard covers it; its group here is AKC Toy group.

Questions people ask

General guidance for dogs rather than a measured Toy Fox Terrier figure: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later, so a toy breed is most likely at the early end.
