Known also as the Japanese Mastiff, the Tosa hails from Japan. In fact, these dogs come from the Tosa Province, so the dog was named after the region where they were bred.
It is why they are sometimes referred to as Japanese Mastiffs. The Tosa is a rare dog breed and unfortunately, the dog is still used in Japan for dogfighting.
The breed was developed in the 2nd half of the 19th century, with a number of dog breeds being involved to bring about a more powerful, braver dog.
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.

All four legs are straight, and the hips are well formed. They have round feet and an undocked tail.
The Tosa isn’t recommended for first-time dog owners, as in the wrong hands, they can become aggressive. Care has to be taken around children too especially undisciplined ones.
He also doesn't come as recommended for small, cramped homes in the city. He’s just too big and he will need to get out and be walked often.
You want to create a home for him that ensures he is the calm, gentle dog he is capable of being, If you’re fair, firm, caring, patient and consistent, then this big dog might be for you. With the right care he becomes a gentle, devoted pet.
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 Tosa is a formidable looking molossoid, but even so, this big, calm dog can succumb to illness. Some of these diseases you need to be looking out for include bloat,hip dyslasia and eye conditions.
Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly. Bloat is when gas can't escape, the stomach swells and twists – very dangerous. Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.
To help with eliminating health issues always choose a reputable Tosa breeder. You’re not likely to find one of these dogs in a dog shelter.
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.
These large, strong dogs do well on good quality food. If you opt to buy him commercially manufactured food, make sure it is the top quality one free of unwholesome ingredients such as preservatives, colorants and useless fillers.
Invest in the best quality ones that have nutritious minerals and vitamins. Try and give your dog some home-prepared food too – boiled chicken, brown rice or pasta, spinach, sweet-potatoes and carrots.
Never feed your dog things such as chocolates, peanuts, crisps, grapes, onion and food with spicy flavorings. This will just ensure digestive problems and having to get your dog to the vet.
The Tosa’s short coat isn’t going to require too much attention. A good brush twice a week will keep it free from loose hair and keep its shine and gleam. It’s why the dog is looked upon as being low maintenance.
Beyond that, he will need to have his nails trimmed. When brushing him, check him over for parasites – ticks and fleas, check for unusual lumps and look inside his ears for signs of redness.
These dogs are calm and fairly low-energy. Nonetheless, to maintain good health, he will need to be exercised. Ball games outside are always a good idea as well as nice long walks. Hikes into the countryside will be wonderful for this big dog.
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.
