Product Backlog is dynamic, so this is a risk?
I'm reading Scrum Guide and says that Product Backlog is dynamic, because never is complete and is changing when new requirements/elements must be added to met the objective.
As you know the customers all of the time are trying to add new features in order to met with the expected result and the environment conditions, so in this point my question is:
What is the best practice for try to avoid big changes that could to impact in project scope or in the project finish? Even knowing that sometimes the end customers thinks that the change is simple, but all of the times this 'little changes' could be big if requires modifications at other elements previously complete ...
Really appreciate your feedback

Scrum practice is to have a Product Owner who is the final arbiter on product value and the content of the Product Backlog. This is an important role, and involves liaising with customers and other stakeholders, and being accountable to them for the Return On Investment.
In addition to what Ian said, it depends on the type of project/organization e.g. if you are working for a service based organization and your company working on the fixed-price model then PO has to make a call between original scope vs new feature by doing the cost benefit analysis. He should not keep building a product which no one wants but he cannot keep adding new requirements into the backlog at the expense of vendor company to keep his/her users happy. That's why PO is a really tough role to play in critical situation.
you are right, the Product Backlog is never complete, same as the product. This means there is no such thing as a project scope or a project end, because SCRUM is not a project management methodology. The idea of product development with SCRUM is rather made for real products, think of facebook, google or ebay. They are never "complete", even if it may happen that a product is discontinued for whatever reason.
You may look at changes as oportunities to make the product better rather than risks for your project or threats for your existing product in which you invested a lot of work.
Thanks a lot for your responses guys
