...unless you're suggesting there was some sort of Cave Cow, that lived with early man, and helped them hunt and to protect their clan. That would be awesome. And that /is/ clearly what you're suggesting. I mean, there's not one iota of evidence that shows it's not true, so it obviously happened.
My apologies to canines everywhere ... I did not have intentions to offend ... I should have added 'in no particular order' ... please extend my sincerest regrets to the others mentioned too.
I was just too careless, I deserved to be cave walled. I had been preoccupied with some problems of a personal nature.
