Bond with your puppy. Bring him into your home, into your family, into your life. A puppy can't learn how to behave around people if he's never allowed in from the back yard. An unsocialized puppy too often becomes a shy or aggressive dog. Talk to your veterinarian about when and where it's safe to take you pup out, and then get him visiting.
Puppies are cute chewing on a slipper or jumping up for a slurpy kiss.
Dogs are not. Remember always that preventing bad habits is easier than fixing them. No matter how bratty he is, no matter how tired you are, always reward your puppy for doing it right. If you find you're not getting through in training him, find a trainer and get help before it's too late. Make good manners a part of his regimen from the beginning.
