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."
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.
