There are more than sixty million dogs in the United states. Only 10 percent of those dogs have had obedience training. Historically, dog owners have trained their own pets, or they have just let them go. Poor training or neglect allows a dog's bad habits to surface. Mistreatment of dogs often occurs when owners cannot control them.
Dog trainers are often the only ones who can correct dogs of their bad habits.
The field of dog training has drawn criticism recently. Unqualified persons, at the very least, fail to train the dogs. Some hurt dogs by using cruel methods. Unethical trainers may teach dogs to be violent. This field needs qualified trainers.
