It has been described before that the occurence of raindeers is strangely low, while this was the main food source. But isn't it even stranger for dogs? Recent genetic research suggest that dogs were domesticated a lot earlier than any other animal, which makes sense for hunters. The distinction dog/wolf may be blurred over long times - and while e.g. chauvet cave pictures a wide variety of wild predators, even owl and hyena, no wolf is pictured either.
Where dogs/wolfes too 'ordinary' to be portaied here, more so than raindeer?
