I am presuming that you are on separate tickets and are not checking your bags through DFW-INTL DESTINATION.
Under DOT rules, you are subject to at least the baggage allowance for your first segment on a ticket for all segments on that ticket. Thus, if you are assessed a $25 fee for a bag from DFW-JFK, you cannot be assessed more than $25 for your JFK-INTERNATIONAL-JFK-DFW.
