Real dog breeders don't accept red envelopes. They will let you buy a tutorial and then take charge of after-sales remote guidance. What cheats you is cheating in the name of keeping a dog. You wronged a dog, because I not only learned to raise a dog, but also joined the kennel division. The members of the Dog Trainers' Union are very ethical. If you don't train, pay the deposit first, then bring the dog for training, and then pay the final payment after training! Buying a tutorial requires the dog owner to scan the code on WeChat and pay attention to the official education platform of dog culture before buying. Others can't buy it instead of the owner, so it's not the dog road that cheats you, but others cheat you in the name of the dog road!
