The best period for puppy training is between 3 and 4 months old. Basic etiquette and obedience training can be conducted on puppies between 3 and 5 months old, such as sitting, lying, standing, leaning, following, barking, waiting, etc. Shaking hands, urinating at designated spots, refusing to eat, etc. Small-intensity running and jumping training can be carried out at 6-8 months. Some professional obstacle training can be performed between 8 months and 1 and a half years old. Note that the training time should not be too long and should be controlled within 15 minutes. If the time is too long, the dog will feel tired and affect the training effect. In addition, training a dog over one year old will take more time and energy than when it was a puppy, and it will also be a test of the owner's patience.
