You Internet Trainer: Training dogs definitely cannot be separated from the stimulation of rewards, which can include toys, treats, and petting. When giving dogs reward stimuli, owners need to do the following: 1. The difficulty of the training differs, so the rewards given should also vary. For example, for low-difficulty training, just some petting stimuli are enough, while if the dog completes more difficult training, they can be given treats that they don't normally get as stimulation. 2. Rewards should not be given too frequently. No matter what kind of reward, if given non-stop every day, eventually the dog will think these rewards are things they should normally get, making new training more difficult. The owner will have to prepare better treats or toys to get the dog to complete new training.
