To unlock this achievement, you will have to be located in Tommy’s Dam, the hydroelectric dam.
Walk down the path with Tommy as he speaks to you and you will find a dog lying down on the ground playing with a ball.
You will have to get close to him until your character has a command to click. Once you get close enough and in the right direction facing the dog from the front you will see on your screen that you can pet the dog like in the picture down below.
Once you have done that, Tommy starts talking about the dog, he tells you that the dogs name is Buckley and the isn’t good for protection, but he is a great company.
After your character stand up you will see in the top right corner a PS4 window that shows you have unlocked the “Who’s a good boy?” achievement.
