It would take several generations and it would still be risky. Dogs originate from wolves but have been crossbred for thousands of years to be trustworthy pets. The instincts that would allow them to survive in the wild has mostly been bred out but a few still have the pack survival instinct.
Wild animals that have been in captivity for only 100 years or so are still mostly wild. Take American Bison for example. People have been raising them in captivity for generations but they still retain a lot of “wild” and can’t be trusted. Wolf/dog hybrids are popular but they are dangerous IMO because they are a very confused animal. You never know part you will see in every situation.
IMO, no animal, domesticated or not, is completely trustworthy during breeding season. Even perfectly raised dogs can be different when breeding or raising pups. I’ve lived on a farm all my life and raised cattle, horses and hogs. You never turn your back on a bull, a boar hog or a stud horse during breeding season. :-)
Thank you for your real-world insights. This is why I always turn to FR’s “Broadband Journalists” for my news and analysis.
