First－time dog owners may encounter many problems getting to know and train their pets. Sometimes a puppy, or even an older dog, will chew their fingers or bite them. Even in play, this can really hurt. Unfortunately, many pet owners tolerate (容忍) this in a young dog. However, when the dog gets larger, it is not fun to be bitten by it. Training a dog never to place his teeth on human skin or clothing is an important lesson. From now on, if you feel your dog’s teeth while you are playing with him, say “Ouch” in a loud voice and move away from him. He will soon learn that when he bites, you will not play with him any more.

Another bad habit that many people tolerate in their pets is allowing them to bite and hold on to clothing. Don’t let your dog do this to you. When he does something you what him to do, praise him and tell him he’s a good dog. You can also give him a treat at the same time he performs the good behavior. Eventually he will learn which kind of behavior is acceptable and which is not. Remember that reward is more effective than punishment. If you reward your dog when he does what you want to, he will become very well behaved. Also remember that puppies need to chew on something. So give him a sock with a knot tied in it or an old shoe. If he chews the wrong thing, take it away while saying “No” and give him something he can chew. If dogs are trained well, they will truly be your friends for a lifetime.
