First let the dog sit facing the owner. Then the owner held a snack in one hand and spread it on the floor with the other hand. When the dog sits, the owner says "shake hands" to it, and then taps one of its forefoots with his hands. If the dog's foreleg is naturally raised, you should take the opportunity to hold the dog's foreleg.
What if the dog doesn't respond? Boss, be more flexible, you can move your fingers to attract the dog's attention. Once the dog stretches out its paw and touches your hand, reward the dog for snacks.
You are slightly off the ground and repeat the training process just now. Of course, as long as the dog completes the handshake, you must continue to feed the dog snacks, otherwise it will not do it.
Now you can gradually raise your hands and finally reach a satisfactory height. OK, it's OK too. Handshake training is very simple. Generally, smart dogs can master them in more than ten minutes; stupid dogs can only take 1 or 2 hours. Then, you just need to repeat the process and slowly remove the snacks. Finally, the dog will take the initiative to "shake hands" after hearing the command.
