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.
Food, shelter, exercise and regular visits to the veterinarian are all a part of the basic care package that accompanies dog ownership. However, there is one more important aspect of proper canine care that must not be forgotten or neglected, and that is grooming. In order for a dog to stay clean and healthy, proper hygiene must be maintained, and given that dogs can do little more than lick themselves to remove the occasional annoying substance, grooming of your animal is your responsibility.
Half the battle of dog training is finding the right training class and the right trainer to assist you along the way. Not all dog trainers or classes are created equal! There are a lot of differences among trainers, and you need to be prepared to find the best one for you and your dog.
