I certainly agree with connections with AnubisOh one more thing : if not Anubis, then maybe St Christopher (patron saint of travellers) who was often depicted as having the head of a dog. Or maybe both of these... and maybe even more. I think the layers go deep in the Tarot.

This is a picture of the fool of an Egyptian black and White set; the Fool (Narr) is pictured with the fool (and a crocodile)

Thanks for sharing St Christopher related to the dog on the Fool's card! A patron for a traveller suits very well.
