The coat of the Russian Tsvetnaya Bolonka is one of the main characteristics of the breed that distinguishes it from other Toy breeds. The coat has a natural curl, and the head has a beard and moustache which create the breed’s charming appearance. To achieve and maintain the curl in the coat, it is recommended by breeders that the Bolonkas are allowed to dry naturally, allowing the natural oils to remain.
From the Standard: “The coat is long, dense, thick, soft, and supple, with a well-developed undercoat. The coat forms large curls (preferred) or may be very wavy. The head has a well-developed beard and moustache. The coat is never deliberately parted.” The coat should not be straight.
The Russian Tsvetnaya Bolonka’s coat comes in any color “except solid white, spotted, parti-color or merle.” A small amount of white on toes and forechest is permitted.
Puppies will begin to change coat gradually over time, starting at about six months. Some puppies do not have an abundant curl prior to this change, but it forms as they get older. By the age of 12 months, most Bolonka have a completely changed coat and have their full curls. There are various levels of curl; large and small ringlets or just big waves. The coat should never be straight or lack undercoat.
If a judge cannot tell if an exhibit has the correct coat due to being blown dry or straightened, it is lacking a key characteristic of the breed and must be faulted for that.
