A male should reach full zize by a year. If your dog has a smooth coat it will be short. If he is a rough, it should be longer and softer and you'll see the "feathers" or long hair on the front legs and tail. Some rough collies tend to have more hair than others, but you should easily be able to tell a smooth collie from a rough.
