Did Dogs Help Humans Outcompete Neanderthals?

Humans entered a Europe after Neanderthals were already well established. Why did Neanderthals vanish. Given human nature, it’s hard for me to believe there wasn’t a fair amount of conflict between the two groups, but you needn’t assume humans wiped Neanderthals out.   National Geographic offers an alternative explanation consistent with known facts,

Unlike Neanderthals, humans had spears and bows and arrows, weapons that could kill from a distance. And also unlike Neanderthals, humans had dogs, or at least something between wolves and what we think of today as dogs. These wolf-dogs, as the article refers to them, helped humans hunt successfully. As the Ice Age intensified, an edge in hunting gave humans an edge in survival.
