The entanglement dynamics of an anisotropic two-qubit Heisenberg XYZ system in the presence of intrinsic decoherence is studied. The usefulness of such system for performance of the quantum teleportation protocol \cal T0 and entanglement teleportation protocol \cal T1 is also investigated. The results depend on the initial conditions and the parameters of the system. For the product and maximally entangled initial states, increasing the size of spin-orbit interaction parameter D amplifies the effects of dephasing and hence decreases the asymptotic entanglement and fidelity of teleportation. We show that the XY and XYZ Heisenberg systems provide a minimal resource entanglement, required for realizing efficient teleportation. Also, we find that for the some special cases there are some maximally entangled states which are immune to intrinsic decoherence. Therefore, it is possible to perform the quantum teleportation protocol \cal T0 and the entanglement teleportation \cal T1 with perfect quality by choosing a proper set of parameters and employing one of these maximally entangled robust states as initial state of the resource.
