In some countries they allow it and more people have started adopting them since theyre cute but from what i've seen though theyre very difficult and hard to keep, a lot more than a bad dog would be.
Tend to be very territorial
and stinky
big yard and fences that go underground would be important since they like to dig
specialist vets maybe, im not sure how many vets will be confident for foxes lol
expensive but cute so worth it if you can afford the makeover and trouble
It took hundreds/thousands of years to create the domesticated cat/dog breeds today, less than the 20-50 years of fox domestication but apparently even wild foxes are becoming braver and entering suburbs for food from people.
