Verbal Statements - Correct your dog verbally with short, sharp statements. Simply say no and direct them to what you want them to do instead. Also speak with authority so they understand you mean it.
Proper Grooming - Some dogs require a small amount of grooming, while others may require meticulous grooming each week. When the dog is well groomed, it is happy and healthy.
Be Consistent - When you are home, take your dog outside hourly. When he does use the bathroom outdoors, give him lots of praise. If your dog has an accident in the house, never harshly reprimand it. After your dog finishes drinking or eating, take him out for 15 to 20 minutes. Also, be sure to take him outside after he has exited his crate.
Training Time - Training sessions should be no longer than fifteen minutes at a time to help ensure success. Always reward your dog with praise and attention after a training session.
As you can see, dogs are trained for a variety of different reasons and applications. Since dogs are eager to please, most breeds are easy to train.
