Permutations and Selection

 
Eight dogs are selected for the final round of a dog show to compete for best of show. how many different ways can they line up to enter the ring. the judge then randomly chooses the dogs to parade around the ring in a circle. in how many ways can this be done?
 
I figured out that there are 40,320 ways for the dogs to line up and 20,160 ways for the judge to pick them.  My question is why is the second answer half of the first?
