All dogs need to be exercised everyday in some form or fashion. The most common method is through the walk around the neighborhood, but is a short walk around the block enough exercise for your particular dog?
Historically, dog shows and other related events were developed with a very specific purpose in mind – to select and recognize those dogs with the best breeding characteristics, in order to guarantee the future health, stability and vitality of individual breeds. The practice of dog breeding is dedicated to this purpose, and dog breeders have a responsibility to do what is best for the breeds with which they choose to work.
For the health and wellbeing of your dog, training should really not ever be considered an option when owning a dog. Well trained dogs are more likely to be behaved and listen, be void of behavioral issues, be good in public, and are less likely to bite. Owners also have a much closer connection with the dog when the time is taken to form a relationship through training.
