American indians had dogs too. Pretty sure those dogs did not originate in Europe 15,000 years ago.
Where did they get their horses?
There is evidence that Europeans have gone to China 15,000 years ago or more, so it’s possible that the ancestors of Indians acquired them from Europeans.
Yup. They're still here too...mostly still living in the wild.
(An article I posted here in 2001)
"Genetic (mitochondrial DNA) testing being performed at the University of South Carolina, College of Science and Mathematics, indicates that these dogs, related to the earliest domesticated dogs, are the remnant descendants of the feral pariah canids who came across the Bering land mass 8,000 to 11,000 years ago as hunting companions to the ancestors of the Native Americans."
