Prong collars (also called 'pinch collars') are a series of chain links with blunted open ends turned towards the dog's neck. The design of the prong collar is such that it has a limited circumference unlike slip collars which do not have a limit on how far they can constrict on a dog's neck. The limited traction of the martingale chain combined with the angle of the prongs prevents the prongs moving close enough to pinch. The collar is designed to prevent the dog from pulling by applying pressure at each point against the dog's neck.
Money. Therein lies the rub. One of the drawbacks to training competitively is the cost. Between class fees and trial entries, this can be an expensive sport. That doesn’t have to deter you, though. Many clubs offer significant discounts on training and entries if you work at their trials, which was a huge help for me. I earned quite a few free or nearly free classes by working trials. The fees for junior handlers (-18) are also considerably more affordable.
Obedience training usually refers to the training of a dog and the term is most commonly used in that context. Obedience training ranges from very basic training, such as teaching the dog to reliably respond to basic commands such as "sit," "down," "come," and "stay," to high level competition within clubs such as the American Kennel Club, United Kennel Club and the Canadian Kennel Club, where additional commands, accuracy and performance are scored and judged.
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.
The best type of dog training for both you and your dog depends on the outcomes you hope to achieve. If you want your dog to learn agility training, go to someone who specializes in those techniques. Regardless of whether you want your dog to learn basic behavior or competitive-level tricks, the majority of dog training is actually about training the owner how to communicate with their dog. Most professional dog trainers agree that a model of training based on positive reinforcement breeds a happy, healthy, well-adjusted dog. The alternative to positive reinforcement training is using force or aggression techniques like physical punishment or shock-collar training to get the dog to do (or not do) a behavior. While the dog may learn how to behave as you direct, it is also learning to communicate with force and aggression, and will in turn use those behaviors on other dogs (or people) that are smaller or weaker than it is. Before signing up with a dog trainer, meet with the trainer and ask for references. Watch the trainer interact with your dog, and make sure they treat your dog with patience and firm kindness. Ask them questions about their training methods:
Electronic collars (also known as E-collars) transmit a remote signal from a control device the handler operates to the collar. An electrical impulse is transmitted by the handler remotely, at varying degrees of intensity, from varying distances depending on range frequency. It is also done automatically in the bark electronic collar to stop excessive barking, and invisible fence collar when the dog strays outside its boundary. Electronic collars are widely used in some areas of the world and by some dog obedience professionals. This technique remains a source of controversy with many dog training associations, veterinary associations and kennel clubs.
There is an ever-growing list of agility sanctioning organizations. The ones you’ll hear about most often in the US are NADAC, AKC, and the USDAA (see below for a more complete list of national and international groups). Each organization has its own rules and style. For example, NADAC courses are spread out and focus on speed. They often challenge the handler to send their dog through the course at a distance. USDAA courses are “tighter” and more technically challenging.
Dogs competing in dog sports, such as flyball, agility or Schutzhund, must be trusted in an open field, off leash and surrounded by other people, dogs, hot dogs, and flying discs. This requires more focused attention on the owner and a better recall than that found in most household companion dogs, and more advanced training than that required for formal obedience.
Certain breeds, such as Doberman Pinschers, German Shepherds, Border Collies, Labrador Retrievers and Golden Retrievers, have reputations as being easier to train than others, such as some hounds and sled dogs. Dogs that have been bred to perform one task to the exclusion of all others (such as the Bloodhound or Husky), or that have been bred to work independently from their handler (such as terriers), may be particularly challenging with obedience training.
Basic or beginner's obedience is typically a short course ranging from six to ten weeks, where it is demonstrated to the handler how to communicate with and train the dog in a few simple commands. With most methods the dog is trained one command at a time. Though there may or may not be a specific word attached to it, walking properly on a leash, or leash control, is often the first training required prior to learning other commands.
Head halters are an alternative to collars that works similarly to a horse halter. The halter fits over the dog's snout and behind its head (leading it to sometimes be mistaken for a muzzle). Halters reduce the dog's ability to successfully pull on the leash, but do not eliminate it. If the halter is used with a sharp jerk on the leash, neck injury to the dog may result, but used correctly head halters have not been shown to cause harm.
Step one of each run is the walkthrough. If you’ve ever been to an agility trial and seen a group of people walking around in the ring with one arm out and muttering commands to an invisible dog, you’ve just witnessed the walkthrough portion of the trial. These people may look three fries short of a Happy Meal, but they’re actually hard at work memorizing the course and plotting out how they will run it.
The idea of using treats to train is often equated with bribery. Truthfully, dogs do what works. If using treats gets them to do what you want, then why not? You can also use the world around you as a reinforcement. Every interaction you have with your dog is a learning opportunity, so when you think about it, you probably don’t use food very often except during active training sessions. So why does your dog continue to hang out? Because you reinforce him with praise, touch, games and walks. Just remember, the behavior should produce the treat; the treat should not produce the behavior.
"Chris really knows dogs and treated all 3 of ours as individuals. The reason I wanted a trainer at first was because my Sammie (Lab mix) was 1 year old and she was thinking she was still a little puppy ( 47 lbs of arms and legs and stubborn will). Walking her was stressful and she went CRAZY at any distraction. Chris taught me, my boyfriend Carlos, AND Sam what to do to get her to be a positive family member. All three dogs listened in different visits and we have the tools to go forward. Defiantly worth the money. Thanks Chris!"
