  • RE:

    Other genomic studies show a different result. e.g., "Pre-Columbian origins of Native American dog breeds, with only limited replacement by European dogs, confirmed by mtDNA analysis" . At least the xolo or "Mexican hairless" , the model for many precolumbia ceramic dogs, and likely the chihuahua genome are mostly precolumbian.

  • RE: America’s dogs

    I grew up in southern WV and in my childhood, we had these dogs everywhere that, like the local people, were at least partially indigenous. We spayed them because of movements nationwide to spay and neuter dogs. There are no doubt some still around but they are very few having been replaced by labradors and etc. Our coyotes however are unique in that they are a hybrid of coyote, dogs, and wolves. I suspect that the dog component of these local coyote are from indigenous dogs. It is also likely that some of the dogs remain in more isolated areas but very few. Sadly, we had no idea that we were spaying/neutering the last of the American dogs. We had several as I grew up that just moved in on us. Wonderful albeit independent dogs.
