Maybe these weren’t doggies, but coyotes or wolves?

It says they DNA tested them. Dogs are genetically different than wolves and coyotes. Indigenous dogs are genetically different than other dogs.

It makes sense that native dogs would flow over to Jamestown. Straying dogs will try to set up a relationship with any humans they meet.
For instance, the native Tasmanian's never had dogs but when the English arrived, a few of their dogs strayed over to the Tasmanian settlements and set up a relationship with them.

Bagged a yote one fall. Took the precaution skinned him out. I’ll be danged if those hams didn’t look good.
