How many herps can people purchase without already having years of experience that could turn around in a blink of an eye and attack causing some bad damage? Sure they are both wild animals and even domestic dogs can be viscous but i don't feel a dingo should be something you get without any experience or good knowledge just 'cause you like them'.
Scrub pythons have killed more ppl than dingos as far as i know, some ppl are even silly enough to trust them. Large goannas could also kill if you are dumb enough to hold them near your throat(as some idiots do). A dog on the other hand CAN be trusted if you know it, probably more so than a human in many cases. I agree that they arnt something you should get without good knowledge same as any other animal really. It would be interesting to know if dingo breeders are willing to sell them to idiots who dont know what their getting into, i would suspect they would actually care about their animals and the reputation of the species.
