Can a four-month-old dog change its name?

Yes, 3-6 months is the best time for dogs to learn and cultivate their habits, so the new names, rules and habits established during this period will be well followed.

Dogs will get used to the tone and eyes when you call him, and even know when you need him, even if you don't call him, they will come to accompany you. This seems to be the dog's nature, so it is said that dogs are human's best partners.
