Puppy Behavior

We are working on trying to get our dogs to behave better, now they are not bad dogs but sometimes they just get a bit too hyper or bark too much. We bought a anti-barking device from the store the other day that sends out a high pitch noise to correct them when they do something bad, it's great and is so high we can't hear it. We are also making them sit and stay when letting them in and out of the house which is making a big differance in their behavior, there is still hope yet.
