How old is Dora's?

Could you please clarify what you mean by "Dora's"? Is it a company, a product, or perhaps a person? Without more context, it's difficult to give an accurate answer to the question "How old is Dora's?" If you're referring to a person named Dora, the age would depend on the individual. If it's a company or product, age typically isn't a relevant factor but rather factors like establishment date or release date might be more appropriate. Could you provide some additional information to help me better understand your question?
