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.
Flat collars are commonly used in clicker training and other non-correction-based training, such as puppy kindergarten. They are also effective in training small dogs, however they tend to lift the dog off the ground when giving corrections while the dog is distracted or in high adrenal mode. They are typically made of nylon or leather, and fasten with a buckle or quick-release connection.
In recent years, a new form of Obedience competition, known as Rally Obedience, has become very popular. It was originally devised by Charles L. "Bud" Kramer from the obedience practice of "doodling" - doing a variety of interesting warmup and freestyle exercises. Rally Obedience is designed to be a "bridge", or intermediate step, between the CGC certification and traditional Obedience competition.
Changing behavior takes time. You need to have realistic expectations about changing your dog’s behavior as well as how long it will take to change behaviors that you don’t like. Often behaviors which are “normal” doggie behaviors will take the most time such as barking, digging and jumping. You also need to consider how long your dog has rehearsed the behavior. For example, if you didn’t mind that your dog jumped up on people to say hi for the last seven years and now you decide that you don’t want him to do that anymore, that behavior will take a much longer time to undo than if you had addressed it when he was a pup. Remember it’s never too late to change the behavior some will just take longer than others.
Seesaw: This obstacle looks just like what you might see on a playground, with one plank supported in the middle, so that either side can be lowered toward the ground. The dog will start at one end and walk to the other, while the plank shifts with the dog’s weight. Some clubs require that this obstacle have grips or treads on them, as a safety measure.
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.
There are many factors that go into choosing the right training school for you and your dog. Certainly distance is a consideration; however, convenience shouldn’t be the only factor that influences your decision. Other things like training methods, appropriate classes for your needs, compatibility of the instructor’s personality with yours, and certifications of the instructor should also play a role.
