You change the tenses when you change talking into the present, past or future. For example, I have a dog. "Have" is in the present tense. If you want to talk in the past you would say "I had a dog" That means you dont have the dog anymore. If you talk in the future. "I will have a dog" That means you dont currently have a dog, but you will in the future. You change them based on when you are talking. If you are talking about right now, use present. You want to say something that happened yesterday or before right now, use past. You want to say something that will happen tomorrow or after right now, use future
Present - I/you/we/they go. He/she/it goes. Past - Went. Future - Will go.
