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.
