I wouldn't call a moustache (on a poodle) to be the same as a teddy bear face. A poodle moustache still has the sides of the head shaved, and just the moustache left around the nose. A teddy bear face has a full beard. Yeas technically it has the mo' too, but I'd never call it that, it's simply a full fluffy faced beard.
Which is the reason you groomer said you couldn't really have just a mo', cos you won't be able to get a fluffy round teddy face if you are shaving the sides of the face down to create a mo'!!
