NEVER USE HARSH DISCIPLINE...DON'T BORDER ON MISHANDLING OR ABUSING YOUR DOG!!
Do not play rough with your puppy! Don’t let the puppy develop bad habits such as jumping up on you, biting at clothing, etc. You must remember that your dog will weigh from 65-95 pounds at maturity. Some of the bad habits that he develops as a small puppy will certainly not be desirable when he grows older. Don’t let him get by with anything as a puppy that you won’t want him to do when he is older and much larger!
Bad, unruly dogs are almost always the result of lack of training or inconsistency, neglect, or abuse on the owners part. In as little as 5-10 min per day, you can have a well-behaved, happy dog that the whole family, friends, and relatives can enjoy.
A sharp, loud "no" is a sufficient reprimand for a puppy. The dog wants to please you. You can also grab the pup by the scruff of the neck and look them in the eye to reprimmand . It also establishes you as the "leader of the pack"...use a warm happy voice to praise puppy when he does well. This is importaint but don't overdue it! Never create a "live-wire" puppy by always playing rough, it is important to teach him to enjoy calm, quiet affection. Use this method with a soft soothing voice often. Limit the amount that children "rough house" with your pup!
Dogs need training and limits but so do their human partners..... Training should be the number one investment in both you and your dog. If training is not a normal part of your day to day activity than you are missing the boat.
If you are unable to be gently and firm and patient with your pet, find another home for it before you give up, abuse, or neglect it. Be wise, and kind.
