Four coat colors are recognized for Rough Collies: All have white coat areas, in the collar, parts of the leg, and usually the tail tip. Note that the American Kennel Club accepts white, where the dog is predominantly white with coloured markings of sable, tricolor, or blue merle on the head and sometimes body patches. The males are usually in the weight range (50–70 lbs), and the females are usually 5 to 10 lbs less. Collies in the US are sometimes reported to be over one hundred pounds, but a large collie typically weighs no more than 70 pounds. US and UK standards may differ.
