The Toy Fox Terrier is an American breed, developed in the early 1900s by crossing small Smooth Fox Terriers with toy breeds. Farmers kept them as barn ratters, and their quick wits later made them circus favorites. Adults weigh roughly 4 to 9 pounds, with a satiny, mostly white coat, a black, chocolate or tan head, upright pointed ears and a high-set tail.
Many are bright, playful and devoted, with plenty of confidence for their size, and they often keep a comic, busy energy through a lifespan of 13 to 15 years. They can also be bossy, barky and fast on the trail of anything small that moves, which counts in a city full of squirrels. Dogs vary, so spend time with a dog before deciding whether the match feels right.
