Biro Yorkie, Biro Yorkshire Terrier

The Biro dog is a rare breed of dog but is becoming more well known all over the world. The cute innocent face, the alert and cheerful demeanor, and the self-confidence of this dog are traits that make them an ideal companion. They suit any home, even the smallest apartment, as they only reach up to approximately 7 pounds. They get their name from the initial letter fusion of the name of the people who developed this breed; Birgit Rosner and Roberto Krah. The dog's attractive color combination of the dark chocolate on a white background and the addition of gold on the head makes the Biro a truly attractive little dog. Combine that with their appealing size and fluffiness, who could possibly resist them? Sweet, mischievous and dainty, but with a personality that is larger than life, the Biro is set to be a high flyer in the breeder's stakes. But even better is the companionship and loyalty that the Biro brings to its owner.

Biro Breed History

The Biro breed began when during the winter of 2004-2005 two puppies from different German breeders were born, both unique in coloration. They were a rich chocolate on a white background and had a golden color throughout their head. Because the breeders liked the coloration so much, they decided to work together and soon began breeding the Biro Yorkshire Terrier. The breed immediately attracted positive attention, which continued to grow. Careful breeding has been adhered to, with the goal of maintaining that attractive coloration. The owners created an acronym of their names, and so Biro was created and registered. While it is too early to tell whether there are any outstanding health problems, they can be compared to their parent breed the Yorkshire Terrier for information. The appeal of the Biro, apart from that delicious chocolate white and gold color, is their size. They can share even the smallest of homes, they adore children, and make great friends of the resident cat or other dogs. The Yorkshire Terrier was bred to hunt small vermin, so that instinct is still there in the Biro. Pet mice that may reside in the home are going to have a hard time with this little hunter; a prospective owner must be aware of the possibilities and the need for vigilance. The appeal of this little dog is size, personality, and appearance, and with more people moving into smaller accommodation, this pup will fit in really well. As a companion to a single or elderly person they are perfect. Like any small dog, they seem to have a larger than life personality and need to be socialized and well trained early in life to overcome any obsessive behavior. As the breed expands its range of habitation, we can expect to see many more of this rare dog.

Biro Breed Appearance

The Biro is a small, long-haired Terrier type of dog that is exclusively chocolate on a white background with a touch of gold to the head. They have a chocolate colored nose, and dark round eyes that are very expressive. The head is small and slightly rounded with a medium muzzle in length, that is in proportion to their head. Their ears are v-shaped and are held erect. Their teeth can meet in a scissor or level bite. The Biro's body is compact in shape and very neat, with straight forelegs and well muscled hind legs. Their feet are small and rounded, well padded and often hidden by their long silky coat that hangs straight from their body. Their tail has an abundance of long fur and is carried high like a flag, although not sticking straight up. Adorable and attractive, this little dog is carving a firm place in the popularity stakes. Their delightful personality is the final touch that will endear this dog to your heart forever

Biro Breed Maintenance

The Biro has the long silky hair much like the parent breed the Yorkshire Terrier. The coat requires a regular brushing once a week to keep it from tangling and looking its best. Their coat is a single one and they shed very little. Bathe this little cutie about every second week to keep their coat beautiful and shiny, using a special mild dog shampoo made to retain their natural skin oils. A conditioner designed for silky, long dog fur may be required to keep tangles at bay. Bathing is a time of bonding and affection and your dog will love all the attention. You may need to dry off your dog and then pull their hair away and back from the eyes, securing it in a band to keep it out of their eyes. Check in their ears and keep the inner ear dry and clean, being as gentle as you can in this sensitive area. Keep your dog's toenails trimmed, just be careful not to clip too close to the nail bed. If in doubt, get your veterinary specialist to show you how to do it. This small canine will need their teeth brushed a few times a week in order to keep decay at bay. Then, just relax and have fun together.

Biro Temperament

The Biro is a happy go lucky little dog who is very affectionate and loves to be with their owner. They are happiest when they feel useful, so train them to do some chores and they will love it. While most are cuddly and perky, some may be mischievous and outgoing. They will need to have set limits and be kept busy with walks and tasks. A bored dog will always get into trouble, so keep your eye on this little furball and the moment they start getting into something they shouldn't , divert them quickly with a game or a cuddle. They are outgoing small dogs who like to be part of family life; they will join you for movie nights, cuddle when you read, and will follow you around to see what you are doing. They are a true companion dog. The Biro dog loves to play with the children, just supervise to ensure the games don't get too rough or your Biro may get hurt. Friendly, outgoing, companionable and loyal, the Biro Terrier is a lively personality whose antics will keep you laughing and happy.

Biro Activity Requirements

The Biro is active inside but doesn't need a lot of exercise. They keep themselves busy around the house but they still do like to go out for a walk and gather admiring glances. A daily walk will keep them mentally and physically alert, and it is a good way to socialize your dog.  They are very playful and will play contentedly with the children or other pets. It is only pet mice that they still have the instinct to hunt, so if you have a pet mouse, you may have to keep it away from your little hunter. Although small, the Biro still likes to get outside and explore. If you have a secure yard they will love to wander around and explore the garden. Just keep an eye on them so that they don't get into trouble or find a hole to wiggle through and go exploring. They love to be part of the family and will expect to be treated as a family member.
