Selective breeding began in 1983. Curls are well balanced, moderately muscled, slender rather than massive in build. They are alert, active, with gentle, even dispositions. Females weigh 5 to 8 pounds, males weigh 7 to 10 pounds. Proper proportion and balance are more important than size.
Allowance is to be made for normal male characteristics.
Size is medium and in proportion to body. In profile the nose is moderate in length and straight, slight rise from bottom of eyes to forehead, gentle curve to top of head, flowing into neck, without a break. Muzzle is rounded with a gentle transition, no pronounced whisker break. Chin is firm, in line with nose and upper lip. Wide at the base and open, curving back in smooth arc when viewed from front or rear.
