If you have gone through the steps in the New Arrival and Growing and Learning sections of this site, your dog should be well on the way to proper behavior. All you have to do is remain aware. Keep correcting inappropriate behavior. Nip new problems in the bud with firm but fair discipline.
If your puppy is still acting up or is behaving badly, you may have to back up a few steps. The Behavior page in our Learning and Growing section has tips on promoting good behavior and correcting a variety of common problems. If the behavior issue is more than you can handle alone, ask your vet to recommend a reputable obedience specialist in your area.
Good Routines for Good Behavior
One common cause is a lack of structure or routine. Look at your puppy. Is he being fed at the same time every day? Getting enough exercise? How about enough bathroom breaks? For some pointers, look at our pages on behavior for new arrivals. You can learn some basics such as setting a routine and learning not to jump.
You may need to learn how to earn your puppy's respect to make the lessons stick. But the reward of a well-behaved puppy -- and later, a well-behaved dog -- is well worth the effort.
Once your puppy has learned to obey and act correctly, keep it up. It is a crucial part of becoming mature, and it is important in helping both you and your incredible puppy enjoy your lives together to the fullest.
