If you raised your dog correctly and adhered to the rules that were outlined by us above, you should not have problems with training. You just need to have enough patience to overcome the internal stubbornness of the pet, while not losing your temper and maintaining a sense of humor.
When working with this breed, you need to put yourself in the role of a leader, and this should not be done with the help of brute physical strength, which is unacceptable with the Chow Chow, but with the help of various tricks. For example, sometimes it is necessary not to give the dog a favorite toy right away, not to feed it as soon as it demands it. The dog must understand that its food, walks, toys, directly depend on you.
