In 'Greek Myths', Robert Graves remember us that in the Bible (along Deuteronomy XXII - XXIII) they speak of the Sodomites, the dog-men, writing: "To the women was forbidden to dress as man, and also to drop to the treasure of the temple 'the wage of a meretrix' or the fee of a 'dog', this is of a dog-priest. Special quarters were destined in the temple to the dog-priests, or Sodomite, as in Kings XXIII, 7". I'm not too sure how much these Biblical quotations by Graves are reliable. Someone else of English mother-language can control them better.
The dog, as domesticated side of the wolf, was not well considered in the Greek-Roman world and to meet a black dog or a howling bitch was of bad omen, according to Horatius. In the pre-Vedic India the dog was not so unfavourable (Rudra was the 'Lord of the dogs'), but after, that creature becomes impure till the point that if a dog or a pig approached the sacrificial fire, a purification rite was necessary. On the contrary, in Egypt, the dog (Sirius) was the faithful companion of the sunrise, and as Anubis was the advocate of the dead in the final judgement.
As for the cynocephalus, in Egypt it represented the lunar god Thoth, as everybody knows.
I do not know exactly the "infamous" Snake Goddess quoted by Savitar, but always in Egypt we see the white and the red Snake-Ladies, Wuadjet and Nekhbet, the same as the tantric Nadi, also visible in the Caduceus.
Finally, the dog-man under the leash quoted by evola_as_he_is, calls the painting of the symbolist Félicien Rops (even if there is a pig-man under the leash), 'Le pornocrate', that the owner know by heart. Unfortunately it's a bit bold to show here...
