The Biewer is, or was, a piebald Yorkie caused by a recessive gene in a breeding of two Yorkshire Terriers. On Jan 20, 1984 a piebald Yorkshire puppy was born in Hunsruck, Germany to Gertrud and Werner Biewer. The puppy was considered beautiful and the Biewer’s fell in love with it and began a process od selective breeding in an effort to breed piebald Yorkies. Based on a friend’s suggestion, they named this group of puppies, “Biewer Yorkshire Terrier a la Pom Pon”. By 1989 the Allgemeiner Club der Hundefreunde Deurschland (ACH) officially recognized the Biewer Yorkie as a separate breed. Today they are recognized world wide as two separate breeds.
Today there have been genetic studies done that have declared the Biewer Terrier to be a separate and distinct breed from the Yorkshire Terrier, not simply tricolored Yorkies. The BTCA (Biewer Terrier Club of America) changed the name and standard to an original one for the Biewer Terrier. Mrs. Biewer has accepted and signed this revised standard and it is the only one she has accepted. This new standard allows the Biewer Terrier to have a black coat and an undocked tail. In 2014 with the new standard the American Kennel Club Foundation Stock Service (ACK/FSS) accepted the Biewer Terrier. Some breeders still want the breed called the Biewer Yorkshire a la Pom Pon, but Mrs. Biewer has objected to this, insisting the dog is a terrier. The Biewer Breed Club of America (BBCA) insists on the breeding of Biewers only to other Biewers. This is opposed by others who are importing Biewers and breeding them with Yorkies. The result is not recognized as a purebred dog. BBCA breeders do not engage in this type of cross breeding or condone them. The BBCA breeds only dogs that meet the standard set by the BTCA.
The first two Biewers were imported to the States in 2003 by Donna Hall. They made history in 2003, when they were accepted by the IABCA (International All Breed Canine Association) and entered their first dog show. Today they are shown in rare breed dog shows around the world. Today there are two standards in operation for the Biewer as the American Biewer and the North American Kennel Club continue to follow the German standard while the BBCA follow the revised standard approved by Mrs. Biewer.
The Kai Ken dog hails from Japan and is both an ancient and rare dog. In fact the dog was discovered in 1929 in the Kai province near Mount Fuji. The dog has the nickname Tora Inu in Japan which means 'Tiger Dog'. Maybe its got to do with the brindle striped coat or his bravery.
He falls into the working class category. In 1931, the Kai Ken Aigokai registry was formed to preserve the dog. In fact in this year Dasuke Adachi discovered these dogs and in 1934 was actually designated a Natural Monument in Japan and also protected by law.
The Kai Ken was recognized in 1934 by the Japanese Kennel Club. It is not 100% certain but it is thought that the dog was brought to the United States in the 1950s.
This long-haired terrier is a neat and compact toy dog. Their hair should be as long as their body is high and hang straight from the bottom of his skull to the end of his tail which is carried upward. He is a well proportioned and powerful little dog. He has no undercoat, but his overcoat is very much like human hair and should be combed. The head is a signature of the Biewer, covered with symmetrical gold, white and blue/black hair. They have flat, small heads and a black nose with an average muzzle. They have intelligent, dark, medium sized eyes and small ears shaped as a V and standing erect. All four legs are straight, and the hips are well formed. They have round feet and an undocked tail.
The Kai Ken has always been used for hunting purposes. He comes as recommended for hunting people and those who are active.
It is a medium sized dog standing at between 43 to 56cm in height both male and female and weighing between 14 and 22kg.
The ears of the dog are erect, the muzzle is fairly tapered and the nose is black. The tail is bushy like that of a fox and curls over the back. The double coat of the dog is of medium length and harsh and is a brindle color in a reddish or black shade.
Puppies are born black and then the brindle stripe-like pattern comes in later. He has an athletic body and is a keen swimmer.
The Kai Ken is an intelligent dog, loyal to his human family while being somewhat reserved around strangers. They are amicable with both children in the home as well as other pets.
He is a friendly, intelligent dog, forming close bonds with his family. Have him trained and socialized and he'll make you a splendid pet who will be willing to guard you if anyone threatens.
One look at that bright face and you can see that he is an intelligent, independent dog. He is also courageous and fearless and makes a great watchdog, especially because he is naturally reserved and suspicious with strangers.
The Biewer Terrier loves to be loved and he returns it in volumes. This is a dedicated, fun loving and charming little dog that you can carry around. They are loyal and friendly, athletic and alert. They are barkers when they need to be, but they are not “yappy dogs”. They love toys so make sure they have plenty. They will carry them wherever they go.
The Kai Ken is a working- and hunting dog, so he is used to being active and will want a home where he can be played with and exercised regularly.
He can be slightly stubborn and independent so training and socialization are imperative. This is also because the dog’s curiosity and his athletic skills can lead to trouble if he isn’t properly trained.
Treat him the way he deserves and you’ll see that he is able to develop a strong bond with you and be altogether an excellent family pet.
The Biewer Terrier is not a cross breed or hybrid and so does have some of the very serious health issues of the Yorkshire Terrier including the bane of small dogs with liver shunts. Liver shunts are fatal if they are not treated. The breed does have sensitive stomach issues as well. They face other small dog issues like floating patella’s, ear and skin infections. Other than this the Biewer Terrier is a very healthy breed.
With a lifespan of 14 to 16 years, and given the genetic purity of the Kai Ken, you aren't likely to battle with congenital health problems with your dog, but it is always good to be aware of certain minor health issues that he could succumb to.
He can suffer from a few common dog diseases such as progressive retinal atrophy or hip dysplasia.
This is a disease of the eye where there is wasting of certain parts, and in this case the cells of the retina develop abnormally. This can eventually lead to blindness. It’s an inherited disease that can occur in pure- and mixed breeds, and dogs with PRA shouldn’t be used for breeding.
It isn’t a painful condition, and the first symptom usually noticed in a dog is night blindness where you may notice him bumping into things at night and being reluctant to walk around in the dark.
As previously mentioned the Biewer Terrier has a very sensitive stomach and intestinal system. He should be fed low protein dry dog food. Watch for signs of food allergies such as scratching or chewing on his feet. Feed 2-3 times a day but the Biewer Terrier is one of the few dogs that you can safely free feed unless you notice substantial gaining of weight.
Health issues are few as mentioned previously. However, make sure your Briewer’s ears are free of debris and wax, make sure their teeth are brushed and they show no signs of allergies. Along with liver shunts, sensitive intestinal and stomach issues and floating patellas, these are the other minor issues that might occur. Watch for diarrhea and off colored stools.
The Biewer Terrier is an active dog that needs regular exercise and walks. He is a speed demon as his ancestor the Yorkie is and needs an outlet for running as well as daily walks. They love to run, and they love to play. They do great in agility but love adventures. They are smart and love to learn tricks. Since they love hunting vermin they would also excel at Barn Hunt.
Even though the coat is thick, the Kai Ken will require basic canine care, so a brush twice a week will be enough to keep the coat free of loose hair. He sheds more heavily a couple of times a year and then he will require more brushing.
He has always been used to hunt so he is a dog that will require regular exercise such as walks, hikes, swimming and ball games.
The nails of the dog should be trimmed regularly once they become long as long nails can be hazardous and can hook onto things, causing injury to the nail area.
The ears of the dog should be checked regularly for fleas and ticks, and teeth should also be brushed with canine toothbrush and toothpaste.
