Bichons weigh between 7 and 18 lb (3 to 8 kg) and stand 9 to 12 inches (23 to 30 cm) at the withers. They have curly, soft, white fur that must be groomed regularly and carefully to maintain a neat appearance and avoid matting. Professional grooming is recommended to achieve your best looking Bichon. Their tails are usually left longer in length, and carried curled over their backs. Black eyes, nose, and lips provide a striking contrast to the all-white fur. Often times, Bichons appear to be smiling.
Bichons do not shed. As a result these dogs are one of the hypoallergenic dog breeds popular to people with allergies. Though they are not nonallergenic, it is still possible to have an allergic reaction to a dog of this breed, it is simply less likely than it would be with some other breeds.
