How can I train a dog to do this? Talk about training methods

First of all, take the dog's favorite snacks in your hand, make them into fists, hold them at the height of its eyes, keep the distance between fists, and repeat the "handshake", which should be clear, definite, decisive and firm. Dogs will smell it. Don't loosen your fist. Then the dog will try to open his fist with its claws and put a paw on your fist. As soon as it does, you loosen your fist and praise him. Then practice over and over again, and finally the dog will shake your hand without food.

Next, let him shake hands with two claws. Then use food, repeat "bye-bye" or other commands, and it will immediately put a paw. You put your other hand on its other front paw, loosen your fist at once and give him a compliment. Repeat this exercise, and it will know what you mean and make this action.

Hope to adopt!
