My dogs loved showing, if they didn't I wouldn't have shown them. They enjoyed the pampering when being groomed before being shown, they enjoyed the time we spent together training for the show and they enjoyed hanging out together at the show. They really enjoyed it when they win one.
Any dog which does not enjoy showing will not "perform" and so will never win anything. Therefore the owner will stop showing the dog as it is a pointless exercise.
Alot of dogs which are shown also participate in activities such as Obedience, Agility, Flyball, Herding, Jumping, Dock Diving, Field Trials, Schutzhund, etc, etc, etc.
In many ways show dogs are far luckier than alot of pet dogs as their owners spend so much more time with them - grooming, training, exercising, showing, etc as well as being pampered with the highest quality dog food, etc.
