Second, it’s easiest to ignore unwanted behavior and reward an incompatible behavior. When Rover bites at your hands, he wants attention. He wasn’t born programmed to know that you want him to sit and ask nicely for attention, so you have to teach him. Instead of scolding him, ask him to sit. When he complies, reward him with a food treat, lavish praise and petting on him, or offer a game of fetch or tug.
 I felt that Hilton was able to apply various protocols to meet my dog’s needs due to his extensive background with K-9 training in the military, police, and service dog environments. Hilton demonstrates a firm hand while training, but uses positive reinforcement as well, which was needed for my dog. He ensures that you know the protocols to carry over in the home environment after training is complete. If there was any question regarding Auggie’s behaviors at home, Hilton was available by email, phone, and even conducted follow up sessions at my house. 

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.
Herding breeds like border collies are the masters of this game, which is why you’ll see a ton of them at trials, but they’re not the only players. Chihuahuas, pit bulls, huskies, hounds, even Great Danes. You name it, my dogs and I have probably been shown up by it at some point. Surprisingly, certain toy breeds like Papillons have a real knack for agility.

Tunnels: There are a couple of different types of tunnels used in agility competition. One type is a tube with a U-shaped bend that is made of joined rigid hoops. Another style consists of a stiff collar-like tunnel, usually only a few feet long, that has a length of fabric fastened to one end. The dog goes in through the collar portion and must find its way out from under the collapsed fabric portion.
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.

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.
According to the USDAA, there are over 150 breeds of dogs, including mixed-breed dogs, involved in agility. Some breeds, like the Australian Shepherd and the Dutch Shepherd, are known for excelling at the sport. However, you should not let the fact that you have a Golden Retriever or a mixed-breed dog stop you from trying it. If your dog is playful and energetic, it will probably enjoy agility training.
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:
