Even if the show ring is not your ultimate goal, the relationship that conformation training forms between you and your dog will be rewarding to you both.
Handling your dog is an exceptional and enjoyable experience. Local clubs also have "Matches" where you and your dog can test your skill in the ring.
While training classes offer the best hands-on way to practice for the show ring, attending shows and observing your breed is also a great way to gain understanding of what judges and other competitors do.
