[@ClocktowerEchos] Yeah, when the events were that recent, there is no reason the Schäferkin would have any good opinions about them.

Then comes the question if the Schäferkin helped defeat them, or if they just said to all the others who were fighting them.
"Have fun with the lizardmen, we're gonna keep to ourselves."

I'd guess my species would just be happy to not have to bother with reptiles any longer.
Seeing how the Quixikotl and the Tak'a'dis were both reptilian in their genetic ancestry, would probably put Schäferkin in the seat that reptile descendant lifeforms are all bad, and have a racial tendency of bad luck and probably harbour racist feelings towards them.

So my Schäferkin would probably dislike the Quixikotl, obviously the Tak'a'dis, also Vesians of all sorts are a sceptical concept.
The Covenant would be a whole pile of WTF for Schäferkin but otherwise not harbouring ill feelings towards them.

I'd need to know of the other species before forming any strong feelings for them.
Schäferkin meeting human domestic dogs would also be.... interesting.
