Huh. Pretty clearly a dog/jackal though, right?

Set was the god of Libya and was at war with the "good guy gods" in Egypt, so one has to assume the civilization based in Libya would be were we could correlate the answer -- and we have the contention that the Sahara has grown since the early days of Egypt, so its possible the definitive answer remains buried.

Aardvark to me. Similar snout, long ears. They were probably in the southern reaches of Egypt.

With regard to differences that could be explained by stylisation and the lack of familiarity due to it's rarity in most of Egypt.

Could be a combination of stuff too like a birds beak shoved on a cat shoved on a human body.

They already had a jackal god in Anubis which is represented without the weird down slopping snout and squared ears.
