Can I bring my dog into the office?
Sure. Why don't you bring him with you today?
I don't know why not so i'll find out
Make sure you ask your boss and coworkers if they are okay with it. You don't want to bring your pet unexpected and someone gets upset.
What if my boss does not allow pets in the office?
Then you shouldn't bring him in. It is only okay if your boss says it is otherwise you might get in serious trouble.
