Dragons, Dogs & Amadillos?

[VViews]

Following discussion on the Ladies with Rings thread, I thought it would be better to continue posting here about what else the creature might be.
Has it already been suggested that this could be a hedgehog?
The myth that hedgehogs carried grapes on their backs led to the convention of representing them like this:


British Library, Royal MS 2 B. vii, Folio 97v, England, c 1310-1320


Morgan Library, MS M.81, Folio 10v


Bodleian Library, MS. Laud Misc. 247, Folio 147v

I think the first image in particular, where the hedgehog is shown with a tail, could make a good candidate.
