The evolution of an homogeneous and isotropic dissipative fluid is analyzed
using dynamical systems techniques. The dissipation is driven by bulk viscous
pressure and the truncated Israel-Stewart theory is used. Although almost all
solutions inflate, we show that only few of them can be considered as physical
solutions since the dominant energy condition is not satisfied.
