Praise your puppy or dog at least twice each hour that you are with the dog when the dog is doing something right. Vary your praise choices, sometimes using voice and touch, other times use food, toys, games, or belly rubs. When your puppy or dog does something inappropriate, remove the inappropriate object, or remove the dog from the inappropriate environment swiftly and immediately replace the object or environment with the appropriate one so that you can praise your dog. 1.Chewing on inappropriate chew item - remove item from mouth swiftly then run to the dog's toy box and encourage and praise the dog to find an appropriate toy, when the dog does, play with the dog and praise. 3.Jumping up on people - swiftly turn your back to the dog until four paws are on the ground, and then kneel down and pet the dog and praise.
Timing is very important.
And let me emphasize that you are not praising your dog for stopping a behavior, but for behaving correctly. This means that you should be praising your dog through normal daily routines as your dog is looking at you, following you, lying quietly, etc. This means that you praise your dog during the good behavior. Timing is just as important in punishment as it is in rewards. Many people have poor timing when they first begin to teach dogs.
