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.

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:
In the twentieth century, formalized dog training originated in military and police applications, and the methods used largely reflected the military approach to training humans. In the middle and late part of the century, however, more research into operant conditioning and positive reinforcement occurred as wild animal shows became more popular. Aquatic mammal trainers used clickers (a small box that makes a loud click when pushed on) to "mark" desired behavior, giving food as a reward. The change in training methods spread gradually into the world of dog training. Today many dog trainers rely heavily on positive reinforcement to teach new behaviors.
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.
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.[6]
But wait, there’s more! Agility gives you something cool to do with your dog. This is important if you have a hard time getting your dog to do what you say. It teaches Fido that you are lots of fun and worth listening to. Compare this to another common activity for dogs: the dog park. At the dog park, you let him off leash and he goes off to do his own thing. Returning to you is no fun because it means he has to go home. You’re not Fido’s best buddy. You’re his chauffeur.
Want to attend a trial? This is a good way to check out a club before you take classes. Check their events page to see if they have any trials/shows coming up. Most shows are held in parks and are open to the public. The atmosphere at most of these local trials is fun and casual. Handlers will usually be happy to answer your questions – just make sure you don’t interrupt them when they’re at the ring preparing for their run.

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.

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.
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.
"Training with John gave me the tools to better communicate with my pup. He is very patient, and willing to work on specific problems or challenges with each person with whom he works. My dogs behavior has improved in all aspects, and our bond is stronger because he understands what is acceptable and what is not. Thank you for helping me get there, John."
