Discourage him from biting or nipping. Instead of scolding him, a great way to put off your mouthy canine is to pretend that you're in great pain when he's biting or nipping you. He'll be so surprised he's likely to stop immediately. If this doesn't work, try trading a chew toy for your hand or pant leg. The swap trick also works when he's into your favorite shoes. He'll prefer a toy or bone anyway. If all else fails, break up the biting behavior, and then just ignore him.
Once your dog can stay, you can gradually increase the distance. This is also true for the “sit.” The more solidly he learns it, the longer he can remain sitting. The key is to not expect too much, too soon. Training goals are achieved in increments, so you may need to slow down and focus on one thing at a time. To make sure the training “sticks,” sessions should be short and successful.
In competition obedience training, “heel” means the dog is walking on your left side with his head even with your knee while you hold the leash loosely. Puppy training can be a little more relaxed with the goal being that they walk politely on a loose leash without pulling. Some trainers prefer to say “let’s go” or “forward” instead of “heel” when they train this easy way of walking together.
Reinforcement can be anything your dog likes. Most people use small pieces of a “high value” food for training treats — something special — such as dried liver or even just their kibble. Lavish praise or the chance to play with a favorite toy can also be used as a reward. Dogs must be taught to like praise. If you give the dog a treat while saying “Good dog!” in a happy voice, he will learn that praise is a good thing and can be a reward. Some dogs also enjoy petting. Food is often the most convenient way to reinforce behavior.
Just as a child needs a caring parent; an athletic team needs a coach; your puppy needs a leader and a clear social hierarchy. If you do not take up the role of leader, your dog will; and you will end up with an unruly, disobedient dog. Many people try to win their new puppy's love by letting the puppy always have its way. Buckets of affection is a wonderful thing for most puppies, but it must be tempered with respect.
