Animate mesh with Vertex group

Hi all.
I have a mesh with particles (fur) applied on vertex group. I made armature and assign some bones to this mesh as parent. If i try to pose bones, the mesh is working ok, but vertex group with fur stays on its place. How do i make it follow the mesh?
Thank you very much.

How did you attach the mesh to the armature? With parenting & auto weight painting? I’m thinking all the vertices in the vertex group for the hair will have to also be weight painted to the bones that will control that areas of the mesh. If you are using 2.5x to do this, when weight painting the vertex group that is the hair to it’s bones, turn off auto-normalize (it’s off by default) or that will subtract weight from the hair group.
