Obliquely propagating dust ion acoustic solitary waves and double layers in an external magnetic field is studied by using Sagdeev's pseudo-potential technique. Anisotropic ion pressure is considered, which is defined by applying the Chew-Goldberger-Low theory. The Sagdeev pseudo-potential is derived considering the Poisson equation instead of the charge neutrality condition so that the length scales of the solitary waves and double layers may be shorter than the Debye length. The ranges of parameters for which solitary waves and double layers can exist are studied in detail.
