Jafox Breed History

Because the Jafox is a new breed, they do not have a history yet. Therefore, the histories of the Japanese Chin and the Toy Fox Terrier will be used for this purpose. The Japanese Chin is a tiny dog that originated in Japan during the ancient times but their exact history is not completely clear. Some say they were brought to Japan by a Buddhist teacher in 520 A.D. while others believe the little dogs were given to the Emperor of Japan by the Chinese Emperor in 1000 A.D. Another story is that they were bred in Korea and brought over from there about 1,500 years ago. Whichever story you choose to believe, all agree that the Japanese Chin was revered by the Japanese people and treated as royalty. Until 1977, they were still known as the Japanese Spaniel and are thought to be a mix of the Pekingese and the Pug. They were popular with royalty and were given to Queen Victoria, Princess Catherine of Braganza, and even to Franklin Pierce when he was the 15th President of the United States. The breed was officially recognized by the American Kennel Club in 1888 and is the 108th most popular breed of dog. The Toy Fox Terrier was created in the United States in the 19th century to hunt rats and mice but ended up being even better at hunting foxes. Due to their small size, they were able to get into the fox holes and flush out the foxes for the hunters. They were bred from the Smooth Fox Terrier, Chihuahua, Miniature Pinscher, and Manchester Terrier. They became popular in the United States in the late 1990s and were accepted into the American Kennel Club in 2003 where they are the 116th most popular dog breed. 

Jafox Breed Appearance

The tiny Jafox has dark brown eyes, a black or brown nose, and a slightly rounded head with floppy ears that perk up when listening. They most often have a mask that is white with another color or two such as black, brown, cream, fawn, or sable. The coat thickness and length depends on whether your dog has more of the Japanese Chin or the Toy Fox Terrier but it is usually right in the middle and straight and soft like the Japanese Chin. They have strong but wiry legs and a tail that may or may not be furry and usually curls up over the back.

Jafox Breed Maintenance

The amount of maintenance your Jafox needs depends on the thickness and texture of the coat she ends up with. This is up to the genes, of course, and you cannot really predict how they will turn out unless you get your dog at an older age. However, you should be able to get away with brushing her once or twice a week with a pin brush and maybe a slicker brush. You can trim her nails when needed and clean her ears with a damp cotton ball once a week. Be sure to check for ear mites and excess wax.

Jafox Temperament

While the Jafox is friendly and lovable, they are a large dog in a small package so they are very brave and will sometimes take on more than they can handle. She can be quite bossy and stubborn sometimes too so you may have some issues with housebreaking. Be prepared to use positive reinforcement and a lot of patience. They do have a lot of energy like the Terrier but can also be a good lap dog like the Chin. They should be socialized well at a young age so they are able to go to the dog park without starting fights or need to be caged when your friends come over. 

Jafox Activity Requirements

Your Jafox likes to jump and climb so they are great at agility training and competitions. However, they also like to hang out on the couch or in your lap so you may have to coerce her into exercising by promising her a trip to the dog park or the beach. This breed needs at least 45 minutes to an hour of activity every day to keep from getting anxious or bored. If your Jafox does not get enough exercise, she may develop behavioral issues like excessive barking, chewing on things, or aggressiveness. Try taking her for a walk twice a day and playing a game of fetch or frisbee.
