The Biewer terrier is a charming toy dog that boasts a lush, silky hair. A tiny dog by nature, it weighs 4–8 pounds and stands no more than 22 centimetres at the withers. It has slightly round head, short and neat muzzle, square jaws with a perfect scissor bite, and a long neck. It has medium, almond-shaped eyes that exude intelligence and hairy, v-shaped ears. It has a compact body, which is longer than it is tall.
Like the Yorkie, its long and flowing coat is its crowning glory. It is not only silky and luxurious, but it is also really soft. The long hair on its head is usually tied up in a knot. It comes in these colour combinations: black and white with gold and tan, blue and white with gold and tan, and white with blue or black top lines. Unlike most dogs, its hair grows the way human hair does, which is why it is hypoallergenic and virtually does not shed.
Maintaining its lush hair comes with a price. To keep it neat and free from tangles and mats, daily brushing is needed. It also needs to be professionally groomed because its hair continuously grows throughout the year. Owners that do not show their pooches and prefer shorter hair may trim and clip its hair to make it more manageable.
The Biewer is prone to dental problems, so make sure to start brushing its teeth whilst it’s still a puppy and provide chew toys. To complete its grooming regimen, trim its nails, clean its ears, and inspect its skin for red spots and bumps.
