First of all, you should make some preparations before starting training, prepare the tools needed for training, and let the golden retriever adapt to the training in advance. For example, give the ball to the golden retriever to play with, so that the golden retriever can adapt in advance to having something in its mouth all the time.

Secondly, the passwords for training must be specified in advance, such as "pick up the ball", "no", etc. In addition, the golden retriever must first be trained to obey orders, at least absolutely obey the owner's words, so that the golden retriever can be better controlled during the training process.

Then, try to train the golden retriever. The trainer holds the ball in his hand and throws it far away. Be careful not to keep it too far, and then order the golden retriever to pick up the ball. Of course, when training first begins, the golden retriever is unfamiliar with various commands, so the trainer needs to guide it to pick up the ball. Let it develop a habit. After knowing the meaning of the password, let it pick up the ball by itself.

Finally, when the golden retriever picks up the ball, you must order it back. If the golden retriever can successfully bring the ball to you, then you must give it some rewards. For example, petting it, giving it snacks, etc. are all good ways to reward it.
