Relationships between services

In my project I have several services. Example UserService, ArticleService, LogService and so on. Each service contains functions to create, read, updade, delete, etc. Now the question. When I need to add an item to the User, I use UserService. This, in turn, need to create an object in the log. Should UserService create a new instance of the LogService and use this feature. Or should UserService create this object?

UserService should be aware of some LoggerServiceInterface and should not be aware of it's concrete implementation - LoggerService in your case. LoggerService object should implement LoggerServiceInterface and must be injected into UserService via constructor or setter. I believe you should check out some Dependency Injection Container implemented in your programming language.
