American Kennel Club (AKC)
According to the AKC standard, the Maltese Terrier should present as a toy dog completely covered from head to foot with a mantle of long, silky, white hair. The dog must be gentle-mannered and affectionate, demonstrating eagerness and sprightliness in action while possessing the vigor necessary for a satisfactory companion despite his diminutive size. The head should be of medium length and proportion to the dog's size, with a slightly rounded skull and moderate stop. The drop ears are set rather low and heavily feathered with long hair hanging close to the head. Eyes must be set not too far apart, very dark and round, with black rims that enhance the gentle yet alert expression. The muzzle should be of medium length, fine and tapered without being snipy, topped with a black nose. Bite should be even edge-to-edge or scissors. The neck must be sufficient in length to promote high head carriage. The body is compact, with height from withers to ground equaling length from withers to root of tail. The topline is level with well-sprung ribs. The tail is a long-haired plume carried gracefully over the back, its tip lying to the side over the quarter. The coat is single without undercoat, long, silky in texture, hanging flat against the body with a center part extending from nose to root of tail. The color is pure white; light tan or lemon on the ears is permissible but not desirable. Weight should be under 7 pounds with 4 to 6 pounds preferred, and overall quality is to be favored over size.
Fédération Cynologique Internationale (FCI)
The FCI standard places the Maltese Terrier in Group 9, Section 1, Bichons and related breeds, without working trial. The general appearance should be that of a small dog with elongated, silky white coat, very elegant and with proud and distinguished head carriage. The size relationship requires that the length of the head equals 6/11 of the height at withers, while the length of the skull must be slightly more than half the total length of the head. The skull should be slightly broader than half its length, flat on top with occipital protuberance slightly marked. The frontal sinuses are well developed and the frontonasal depression is marked. The stop is well defined, forming a 90-degree angle. The nose is in the prolongation of the nasal bridge, seen in profile its front face is vertical. It is black, round with open nostrils. The muzzle is straight with parallel sides, measured from the stop to the tip of the nose equals 4/11 of the total length of the head. The lips are thin, rather spare, and tightly fitting with black edges. The eyes are roundish, with lively alert expression, larger than normal size with tightly fitting black-edged eyelids. The ears are nearly triangular in shape, set high above the zygomatic arch, pendant, in close contact with the sides of the skull, thick, and abundantly feathered. The trunk is 1/3 longer than the height at withers. The tail is thick at the root and fine at the tip, forming a single curve whose tip touches the croup between the hips. Height for males should be 21-26 cm with weight 3-4 kg, while females should be 20-25 cm with the same weight range.
United Kennel Club (UKC)
The UKC standard describes the Maltese Terrier as rectangular in proportion with proud, elegant carriage. The breed characteristics emphasize intelligence, liveliness and very affectionate nature while remaining a docile companion. The head length should equal slightly more than half the height at withers, being fairly broad and measuring a little less than half the total head length in width. The skull is slightly rounded with well-defined stop. The muzzle is straight and fine, measuring 4/11 of the total head length, tapering gradually toward the nose but not snipy. The nose must be black and round. The eyes are large, round, and dark with black rims enhancing the gentle expression. The ears are pendant, set on high, and heavily feathered with long hair. The neck has sufficient length to promote high head carriage. The body is compact and balanced with height from withers to ground equaling length from withers to base of tail. The topline is level with strong, taut loins slightly tucked up underneath. The chest is fairly deep, reaching below the elbow with moderately sprung ribs. The forequarters feature straight, parallel legs with lean musculature but sturdy bone for the size. The hindquarters are nicely muscled with sturdy bone structure, straight and parallel from hip to foot when viewed from behind. The feet are small and round with black toe pads, and hair on feet may be trimmed for neater appearance. The tail is set on high and carried well over the back in a plume. The coat is single without undercoat, silky, straight, and flat, hanging long over the sides of the body from a center part almost to the ground without impeding movement. The long head hair may be tied in a topknot or left hanging. The color is pure white, though ivory tinge or traces of orange are permitted but considered imperfections. Height at withers for males is 8¼ to 10 inches, for females 7½ to 9 inches, with weight of 6 to 8 pounds for both sexes.
Other Organizations
The Kennel Club (UK) maintains breed standards closely aligned with FCI guidelines, emphasizing the importance of the silky white coat, compact rectangular proportions, and gentle yet spirited temperament. The Canadian Kennel Club follows AKC standards with minor variations in presentation requirements. Many international kennel organizations including those in Australia, New Zealand, and various European countries have adopted standards based primarily on the FCI model with regional modifications for local preferences. The Continental Kennel Club and other alternative registries maintain similar standards while sometimes allowing slight variations in acceptable markings or coat texture. Regardless of the specific organization, all major breed standards agree on the essential characteristics that define the Maltese Terrier: pure white silky coat, compact rectangular body proportions, proud head carriage, gentle yet fearless temperament, and the distinctive black points on nose, eye rims, and lips that provide striking contrast against the white coat. These consistent elements across all standards reflect the breed's ancient heritage and the centuries of careful breeding that have preserved these distinctive characteristics throughout the Maltese Terrier's long history as a cherished companion breed.
