In the process of getting along with the owner for a long time, the dog will gradually learn to understand human language and instructions. Although dogs cannot fully understand and speak like humans, they can understand their owners' intentions and requests through sounds, intonations, gestures, and expressions. After training and interaction, dogs can learn some simple commands, such as "sit down", "get down", "shake hands", etc., as well as recognize some commonly used words. However, dogs still have limited understanding and expression abilities and cannot carry out complex conversations like humans.
