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:

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.
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.
I've dabbled in agility with a previous dog, but this time I want to go to the show. My 10-month old sheltie is only a spectator now, but the look in her eyes tells me she's ready to become a contender. I've learned from the pros that the road ahead will be filled with training and hard work (for me and for Fiona), but the time spent developing our speed and skills will be rewarded by a canine-human bond rarely obtained in any other activity.
If a dog has a clean run without any faults, it’s called a qualifying run or a “Q,” and they’ll get points added to their official record. If they get a good score, they may also receive a placement ribbon. Winning a first place is a lot of fun, but in the grand scheme of things placements don’t matter until you reach high levels of competition. However, the Qs are important – with enough points, your dog will earn a title. A title is a certificate of accomplishment. As you earn each title you stick it to the end of your dog’s name, so Fido’s name can eventually start to look like Jonas’s. Very snazzy.
Martingale collars (also called limited-slip collars) are usually made of flat nylon with a smaller fixed-length section (made of either nylon or a short length of chain) that, when pulled on by the leash, shortens up tightening the collar around the dog's neck, to a limited extent. When properly fitted, martingales are looser than flat-buckle collars when not tightened, and less severely corrective than slip collars when tightened.
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.

A-frame: The A-frame is a pair of planks joined in the middle at an angle so that they resemble the peak of the letter A. There are “contact” areas indicated by contrasting colors which are painted on the frame and dictate where the dog must step. The dog must go up one side and down the other, contacting the plank in the right places on each side.
"Pamela's approach to dog training is one of the only few in Dallas that does not use treats to train. With this approach, your dog not only listens to you better, but longterm wise they won't keep looking at your hand or for the nearest bag of dog treats nearby to determine if they should listen to you. This has taught my dog to fully understand my commands better and build a better relationship and bonding experience between her and me based on praise training. My dog now listens to me without having to have any treats on hand or nearby."
