AKC Canine Good Citizen (CGC) evaluators are another class of dog-training professionals. AKC CGC Evaluators may or may not be trainers or behaviorists, but are certified by the AKC to evaluate dogs in the Canine Good Citizen test. Training other behaviors and getting a dog used to being alone, for example, can help reduce separation anxiety. The root cause, however, would likely need to be determined by a behaviorist, who could then refer you to a trainer if he or she was not able to help with the training issues.
The training takes place around a set course, and if on a competitive level, training is carried out against the clock. At competition level, the dogs compete against others for the fewest faults in the fastest time. For general exercise, not in the competition arena, the dog owner or handler walks or runs around the course and directs and controls the dog while he’s off his leash.
Even if your pup gets the best start in life, he will still likely develop some “problem” behaviors as he grows up. We put the word “problem” in quotes because most of these behaviors are natural and normal dog behaviors, but they are not welcome in the human world. Behaviors like jumping on you as a gesture of affection, nipping at your hands as an invitation to play, and sniffing you in inappropriate places are all perfectly acceptable behaviors for dogs to do to other dogs.
The fur is flying, the noise is at a decibel I've never experienced before and the desire to win is so thick you can feel it. This is agility competition for dogs and Fiona, my soon to be athlete, and I are on the sidelines of an agility competition taking notes. Dogs of every breed, size and shape are jumping hurdles, running up A-frames, scampering across elevated walkways and diving through tunnels. So as not to get lost on the course, each dog is in constant eye contact with their owner who gives directions through hand signals and one-word prompts.
Prong collars must never be turned inside out (with the prongs facing away from the dog's skin), as this may cause injury against the body and head.  Plastic tips are occasionally placed on the ends of the prongs to protect against tufts forming in the fur or, in the case of low quality manufactured collars with rough chisel cut ends, puncturing the skin. Like the slip collar, the prong collar is placed high on the dog's neck, just behind the ears, at the most sensitive point.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
