χ18Χαλεπὸν χορίου κύνα γεύειν
[it is] dangerous when a dog tastes [the] afterbirth
The covering of the foetus is called afterbirth [chorion]. Once the dogs have tasted this they scheme against the foetuses too, because of greed.
Χαλεπὸν χορίου κύνα γεύειν· τὸ ἔλυτρον τοῦ ἐμβρύου χόριον καλεῖται. οἱ δὲ κύνες γευσάμενοι τούτου καὶ τοῖς ἐμβρύοις ἐπιβουλεύουσι, διὰ τὸ λίχνον.
