Coton de Tulears are small dogs, typically standing between 9 to 11 inches (23 to 28 cm) tall at the shoulder. Their weight usually ranges from 8 to 13 pounds (3.6 to 6 kg). They possess a compact and sturdy build, which contributes to their overall charming appearance.

Coton de Tulears are known for their cheerful, friendly, and affectionate nature. They are social dogs that thrive on companionship and can form strong bonds with their families. Their playful demeanor makes them great companions for children and other pets. While they are intelligent and generally eager to learn, they can also have a stubborn streak, so consistent training and socialization are important.

The Coton de Tulear has a distinctive soft, fluffy coat that resembles cotton, hence its name. The coat is medium in length, dense, and double-layered, providing insulation and protection. The primary color is white, though slight lemon or gray markings may be present. Regular grooming is essential to prevent matting, and they tend to shed minimally.

Coton de Tulears adapt well to various living situations, including apartments and houses, as long as they have regular exercise and plenty of social interaction. They do not do well if left alone for long periods and enjoy being involved in family activities. 

Coton de Tulears require regular exercise to maintain their physical and mental well-being. Daily walks, playtime in a secure area, and interactive games are essential. They enjoy activities that stimulate their intelligence, such as obedience training and agility tasks. They also excel in dog sports and socialization efforts that can enrich their lives and enhance their skills.
