Report of Independent Registered Public Accounting Firm

To the Board of Trustees of DWS Advisor Funds and the
Shareholders of DWS Short Duration Plus Fund:

In planning and performing our audit of the financial
statements of DWS Short Duration Plus Fund (the
"Fund"), as of and for the year ended September 30, 2008
in accordance with the standards of the Public
Company Accounting Oversight Board (United States), we
considered the Fund's internal control over financial
reporting, including control activities for safeguarding
securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on
the financial statements and to comply with the
requirements of Form N-SAR, but not for the purpose of
expressing an opinion on the effectiveness of the
Fund's internal control over financial reporting.
Accordingly, we do not express an opinion on the
effectiveness of the Fund's internal control
over financial reporting.

The management of the Fund is responsible for
establishing and maintaining effective internal
control over financial reporting.  In fulfilling
this responsibility, estimates and judgments by
management are required to assess the expected
benefits and related costs of controls.  A fund's
internal control over financial reporting is a process
designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation
of financial statements for external purposes in
accordance with generally accepted accounting principles.
A fund's internal control over financial reporting
includes those policies and procedures that (1) pertain
to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions
and dispositions of the assets of the fund; (2) provide
reasonable assurance that transactions are recorded
as necessary to permit preparation of financial
statements in accordance with generally accepted
accounting principles, and that receipts and
expenditures of the fund are being made only
in accordance with authorizations ofmanagement
and trustees of the fund; and (3)  provide
reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use or
disposition of a fund's assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal
control over financial reporting may not prevent
or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods
are subject to the risk that controls may become
inadequate because of changes in conditions,
or that the degree of compliance with the
policies or procedures may deteriorate.

A deficiency in internal control over financial
reporting exists when the design or operation of
a control does not allow management or employees,
in the normal course of performing their assigned
functions, to prevent or detect misstatements on a
timely basis.  A material weakness is a deficiency,
or a combination of deficiencies, in internal
control over financial reporting, such that there
is a reasonable possibility that a material
misstatement of the Fund's annual or interim financial
statements will not be prevented or detected
on a timely basis.

Our consideration of the Fund's internal control over
financial reporting was for the limited purpose
described in the first paragraph and would not
necessarily disclose all deficiencies in internal
control over financial reporting that might be
significant deficiencies or material weaknesses
under standards established by the Public Company
Accounting Oversight Board (United States).
However, we noted no deficiencies in the Fund's
internal control over financial reporting and
its operation, including controls for safeguarding
securities, that we consider to be material
weaknesses as defined above as of September 30, 2008.

This report is intended solely for the information
and use of the Trustees, management, and the
Securities and Exchange Commission and is not
intended to be and should not be used by anyone
other than these specified parties.
