There was a study pointing out that Belyaev’s use of domesticated foxes to deconstruct dog domestication is flawed in that not only did these traits already shown up a few decades earlier (perhaps even earlier in Canada around the late 19th century), but that domestic fox populations are more akin to what dog breeds are to dogs. Another problem that they didn’t point out is anthropogenic usage, while dog meat does exist in parts of Africa and Asia even then it’s mostly pretty niche as it’s nowhere as common as say raising goats and pigs for meat.
Dogs are more commonly kept alive for hunting, herding and guarding even if the way they’re trained to do so differs from Western expectations in that some are even starved or drugged in order to hunt, actually some Cameroonians do the same things to their cats. While cat meat is also a thing in Africa and Vietnam, I don’t think they’re really that as common as Westerners make it out to be since it’s rather niche and that more Africans do keep cats alive both as pets and as pest control. As for foxes, they’re more commonly kept as livestock (especially for the rather odious fur industry) and rarely ever kept as pets.
While it is possible to train or make a fox hunt vermin in the same way people have done with cats and dogs, I don’t think it’s ever going to be mainstream not just because foxes are kept as livestock but also because not too many people even bother making them hunt something. There are people like Joseph Carter who do the same thing with American mink but they’re in the minority and as far as I know about Europe, ferrets occupy this role. Albeit far longer and relatively more frequently since Roman times when it comes to hunting rats and rabbits.
You might argue that one can make foxes hunt animals, but the problem’s that it’s not even attempted yet and there aren’t that many people who own foxes to hunt vermin the way they have with cats, dogs and ferrets for ages. Okay, ferrets aren’t that common globally speaking but there are more ferret owners than there are mink and fox owners together.
Another one would be cultural/social attitudes, which means if foxes are associated with witchcraft in China and Japan not only would fox owners be stigmatised but also reinforce their unpopularity (though times have changed for the better). That is the case with cats in southern Nigeria, although there are some people who associate cats with witchcraft in Cameroon and Ghana they’re more commonly kept there if because more people tolerate them. But this proves my point that fox ownership’s rather unpopular.
Even if it were possible to make a fox hunt vermin, that role’s more popularly occupied by cats, dogs and ferrets. I could say many of the same things about American minks, even if it’s already possible to make them hunt vermin they’re not going to be popular and they’re less popular than ferrets, which in turn are less popular than cats and dogs. Foxes may be the genetic relatives of dogs, which they also share morphological and behavioural similarities with but they’re practically livestock more in common with chinchilla, rabbits and mink when it comes to fur.
Cats and dogs can be and are kept as livestock, but not to the same extent as goats, sheep, pigs, cattle and carabao are as they’re commonly kept alive for companionship and hunting vermin. It’s even like that in many African countries, though it does vary between countries but the shoe still fits. If pet fox ownership’s rare, there aren’t a lot of people who keep foxes for hunting vermin either. The role’s long occupied by cats, dogs and ferrets while it is possible to use foxes and mink to do the same thing, it’s not going to be this popular.
If fox domestication isn’t a good proxy for dog domestication, perhaps a comparison to macaques (both rhesus and pig-tailed) would be a better fit. Much like beagles, rhesus macaques are also used in scientific experiments. Like dogs, there are people who train pig-tailed macaques to do something (well, getting coconuts) and there’s even a monkey training school in Thailand. It’s far from perfect, but it’s more analogous to dog domestication when it comes to anthropogenic usage well to an extent but greater than with foxes.
In terms of anthropogenic usage, dogs have more in common with cats, ferrets and monkeys than they do with foxes when it comes to things like picking up something and hunting vermin. You might argue with me in here, but it’s not going to change facts in any way. If foxes and dogs don’t have much in common when it comes to practical usage, perhaps cats and monkeys would provide a better model even if it’s just as imperfect. The only reason why would someone compare foxes to dogs is because they are genetic and morphological relatives.
But fox domestication isn’t and will never be a good analogy for dog domestication when it comes to anthropogenic usage, one gets killed to be made into fur and the other’s commonly kept alive for hunting and guarding. If people were to continue pushing the fox-dog analogy, why not push the lynx-cat analogy since the former’s also commonly made into fur and the other’s kept alive for hunting. Nobody has ever attempted this analogy before, even if lynxes being made in fur is also there before.
Actually even if lynxes and cats are relatives, they differ in anthropogenic usage which’s why the fox-dog analogy’s not a good analogy when it comes to unravelling the secrets of dog domestication. You might as well be shooting yourself in the foot when it comes to coming up with examples of foxes used for hunting and guarding the way dogs have. An analogy to geese would be better, since geese are also used for guarding premises and livestock.
But it still proves my point that fox domestication’s not analogous to dog domestication.
