Golden Retriever (details)
Two people can cooperate, and each of them can take some snacks, which is the best for training at ordinary times. One person is responsible for holding the dog and waiting in place.
One person goes to a far place, and puts some snacks that he usually trains and feeds on the ground. In a far place, don't let the dog find them.
Then, the dog leader goes over and walks the dog as usual, passing by the snacks on the ground. If the dog eats, it will immediately pull and then reprimand, which must be strict. At the same time, another person will put some snacks on the ground in the distance, and then when he leads the dog and passes by, if he doesn't eat, the dog leader will take out the snacks in his pocket to reward him. If he still eats, he will repeat the above reprimand until he doesn't eat.
This is the most direct way to tell the dog that "if you don't eat anything on the ground, you can reward what's in your pocket."
The number of successful training depends on the intelligence of the dog. Like a golden retriever, I think it can be trained in no more than three times. Pippi only used it once, that is, he was beaten once and rewarded once. So far, he has kept it very well. It is not difficult to train those who are dull-headed.
Usually, when you go out, you should take snacks in your pocket so that you can train at any time.
In addition, it's best to get into the habit of playing when going out, instead of just going to the toilet when going out.
The purpose of going out is to "play". Take toys with you and go somewhere to play for a while, so that the dog's attention will be focused on playing, including on the way. He will know that he went out to play again today, and he will pay less attention to it.
One more point: if the brain seeds are particularly dull and refuse to eat, if the training is not good, buy a short leash about 50CM, and take that leash when you go out. On the one hand, it can keep the dog from eating indiscriminately, and on the other hand, it can also help to refuse to eat. If you want to eat, you will pull the leash, and you will understand it more often.
