the tibeten is the clasic tedy cut used on lahsos tibetans sonm bearded collies etc.Looks fine but whenever I look at before and after shots from groomers I often prefer the before look!!!!!!!!!
I would start by asking them to do a very, very light trim or tidy especially since at one point you seemed to be thinking about keeping her quite long and shaggy. Then you can gradually work towards a cut you are happy with.
Take some pictures so they know what you want.
Looking at what they have done to the Tibetan Terriers they seem to do the head/face very squared through the ears and beard. I suppose that's the kind of cut that type has?
Make sure you let them know if you like the shaggy, scruffy look or you may end up with a 'Millie the miniature poodle' look which is what happened when I took Flo.
This is Flo with her poodle cut - I think it was the really squared off ears that bothered me. She has a kind of pityful "what did they do to me" look about her.Poor old Milly - I am going to specifically point to her picture as an example of what I don't want! I don't mind a bit of fluff and I understand about the drying, but a cut like that would make Rosie look like a different dog!
