Thats the point and dogs do acclimate back to the wild without human intervention. They will stay close to civilization because they are scavengers by nature, not predators like snakes. I know this because i have seen this personally with dogs surviving in the wild with no human interaction or no civilization around....
I think you need to reference the actual definition of "domestication" before you try to argue an invalid point.
The fact is this person broke the #2 rule of snake leeping, never leave it unattended with live prey!
Fyi..
Hogs and cats can turn feral or wild prior to the 1st gen of wild birth. This is a documented fact that hogs have actually changed appearances and re-grown tusks or fur after being bred in captivity and released or escaping to the wild. I know these things because I have spent more time in the "wild" than most humans.
If you think your snakes are "domesticated", rub their dead prey on your hands and convince them not to strike...
Even bred in captivity, they are thousands of years from being remotely close to "domestication"...thats a scientific fact. Exactly why they are kept in enclosures to simulate wild or natural environments instead of domestically running around your house...game...set...match!
