Training your dog

It is very important to train your dog. It keeps your dog's mind active, and it helps to build an understanding between you and your dog. Often, owners will shout at their dogs or even punish them when what is needed is training. Training your dog should be fun, and basic training can start when your dog is six weeks old. The best method is reward-based training. If a dog behaves in a positive way, it receives the reward of a treat or lots of praise and then it will want to behave in that way again. However, try to keep your training sessions brief as if they're too long your dog might lose interest.
