One issue though is when running the automatic Recalculate Dynamic Hair which, depending on styling of course,  will follow the prop it is attached to. And setting the collision on will be too heavy for most computers I think because mine usually crash or freeze then.
So the hair prop must follow the animal mesh as closely as possible to avoid strange calculations.
Concidering that I figured it may be easier to simply create a new dog from scratch. We are then looking at a 10 year project for me...

And yes, PhilC absolutely have to fix that!
