The recurring cost of a giant breed in a mobile household is not the move itself. It is the rental market at the other end. Weight limits are the most common pet restriction in private rentals, and a 120-to-180-pound dog exceeds nearly all of them. Privatised on-base housing generally sets its own pet policy, typically limiting the number of animals and sometimes more than that, so the sensible order of operations is to read the policy for the next station before the movers are booked rather than after.
In practice that means a household with this breed searches a much smaller slice of any market, and often pays more for the slice it can reach: a detached rental with a fenced yard rather than an apartment. That premium is real, it recurs at every station, and it is much larger than anything on the veterinary side of the budget.
Jacksonville itself is straightforward. Service pricing sits marginally below the national average, Florida's climate makes flea, tick and heartworm prevention a genuine twelve-month line rather than a seasonal one, and the metro's suburban housing stock means a fenced yard is a realistic expectation here in a way it is not in a dense northeastern posting.
