Im almost certain we will find that Nidhogg's hate goes back further, probably to the Allag. There is no way Dravania was spared from Allag conquest when they were so close to the center of Allag power and that would have almost certainly shaped the views of many dragons.
I also believe it was Hraesvelgr that Shiva had a bond with. If you notice in the biographies Hraesvelgr is the one dragon that refuses to take part in the war. Considering that the two of them were likely working towards peace between their peoples it would make sense that her partner would not vie for revenge. Nidhogg, on the other hand, does indeed seem to have a much deeper hatred. Whether this stems entirely from the loss of his eye I'm not sure. He attacked the Coerthans at the founding of Ishgard (according to the Ishgardian story) so there was likely something even further back that provoked him; possibly something to do with Allag as you suggest.
